Loco Servicing at Chadwick Model Railway | 109.

[@markpini3945]

Hi Charlie another great informative video I might be wrong but I think your the only one that has covered loco maintenance and thorough wheel cleaning well done your video has certainly answered my questions.

[@ChadwickModelRailway]

Thanks Mark, what a heartwarming comment.

[@filip78channel15]

Yes, indeed. My comment is similar.

[@motorheadmalc]

@@ChadwickModelRailway That bit about inverting the rolling road to allow wheel cleaning is just the best, thank you. I have one of those for N Gauge. Btw, those brass rollers also need periodic cleaning. I think some of our cleaning issues arise from contacting two differing metals ie; brass or phosphor bronze pressing on stainless steel or nickel silver with current passing though it. We might be back to chemicals only the other way round, with electrolytic oxidation occurring to producing high resistance points between the differing metals.

[@custardo]

Isopropyl alcohol and water form an azeotrope, which means they form a mixture that is unable to be separated with a simple distillation. As such, the IPA and water portions of any strength of IPA evaporate at the same rate, but the higher the percentage of water, the longer the drying time. Prolonged exposure to IPA can degrade/stain some plastics like PVC or styrenes.

[@ChadwickModelRailway]

Great info Custardo, many thanks.

[@tomd2917]

Yes unless the bottle is very well sealed the 99.9% Propan-2-ol (IPA) will soon end up as 91% by volume the rest water absorbed from the air - can remove it by storing the IPA over molecular sieves but may be over the top of model rail use.

[@ChadwickModelRailway]

Wow, what a great comment.

[@TigerDude333]

From a chemistry standpoint, a water-alcohol mixture forms what is called an azeotrope. This mixture acts like a single liquid, not like sand and rocks mixed together, which will separate out (this is why mixed drinks don't turn into alcohol at the top and water at the bottom). It boils at a single temperature. As such, the alcohol & water evaporate simultaneously, so you'll never have the corrosive properties of water to worry about. No harm using the pure stuff, but really no need, either. By the way, your videos are brilliant, well done.

[@ChadwickModelRailway]

Great comment TD. Regards Charlie.

My first subscription ever on the WWW. I've invested in an 0 gauge model railway that hasn't been used in more than twenty years. Four hundred foot of track, too many rolling stocks to count and eight (?) locomotives. I'm seventy-four years old and, yes, it's for my grandsons (Ha Ha!). A great adventure coming up. Thank you for your excellent website.

I have many locos some over 10 years old that have never been serviced and they run just as well as when I purchased them . Taking things apart will eventually cause something to break or fall off.

Happy new year Charlie, hopefully we will get through this pandemic soon. I wish to compliment you on your superb videos, they are excellent in terms of content, detail and you “explain as you go”...... You also give candid opinions on products, which you substantiate with evidence.....this is what we all need. You said that in a “previous incarnation” you worked with helicopters, well the methodical detail of your profession is well and truly evident in your videos. My own layout is 12ft x 40ft. DCC, with 131 points, all mechanical, “hand from the sky”, operated, and I have no intention to electrify as I love the chance to run up and down checking track etc. Please continue your marvelous videos....

[@ChadwickModelRailway]

What a truly heartwarming comment Brian. However, I would like to see you dashing around changing the points by hand! Stay safe mate, regards Charlie.

[@Zebrails]

I echo the good supportive comments. Um, cleaning the wheel treads and then running the loco's on the uncleaned track is undoing the the tread cleaning and vice-versa. The points and frog tend to collect gunk (where there are wheel power gaps and reconnections causing tiny arcing), any place the loco wheels spin lays gunk on rail sides (not the tops), and finally you will find that where the loco sits (especially on electrified track) over time, is another place where the gunk accumulates. The removal of axles... stick in your "prybar" and once a tab is dislodged, you stick in a corner of your business card to keep it from relocking. And I have found that releasing one "end" at a time puts enough force to bend that axle retaining plate. I pry one side, stick in flat object and pry the other side. On some wheel pick-ups, it's the end of the axles that serve as electrical connections 'as well as' bearings to keep them rolling nicely-but that sometimes requires more dismantling of the bogie/truck assembly (which is also on some tender locomotives' tenders)... to which if there isn't electrical pick up, could be installed with simple brass sheeting and wiring-for those savvy with fine dcc soldering. Arcing is a great gunk accumulater... until you wanna clean and have your loco's running top notch. John BC, Canada

[@willp358]

Hi Charlie thanks yet another top notch video. I think your maxim of " if it ain't broke don't fix it" is a really good one. I think monitoring loco performance and watching for the degradation of performance is the best way of deciding when to intervene. I too have noted less performance when I've serviced which also reinforces the stand off approach. Thanks for the vid its all enlightening. Shame its two weeks to the next but it'll be worth the wait!!!

[@ChadwickModelRailway]

What a heart warming comment Will. Stay safe. Regards Charlie

[@BerlinCardYard]

Dear Charly, there are some points I'd to add to you for your layout to help you. I. Detailing can give some extra dot we do long for So if you like to give your loco drivers a last touch you could add some wash (thinned colour of darkee tone) to the face. A very thinned dark flesh to imitate the shadows in the face making them alive. Also on the uniform a deeper blue/antrazith colour highly thinned will run into the grooves stuck there giving some imitated shadow and bringing the figure a last touch - it is allways easily done at maintenance your locos. Also you could pronounce the detailing on the bulkhead and dashboard, too, if you like. II. The sad guy with the sound issue To reduce the cello body sound of the viaduct you can fill it with styropour balls (may be easiest to bring in through a drilled hole from the "backside") to minimize the acoustic volume of the physically empty but acoustically active body? III. Night shift guy for the 24h journey? I am a bit irritated, because - why were there TWO guys in a loco on a BR diesel loco placed in the cabin? Best wishes to you and thanks you from Berlin, Chris

[@ChadwickModelRailway]

Interesting points Chris, many thanks. However, during this period in time, there were always 2 crew unless the loco was running light. Regards Charlie

[@going2thedogs]

Thanks Charlie, very educational. I have a couple of noisy diesels that I am going to have a look at with a view to lubricating them.

Hi Charlie great video the moto if it aint broke dont fixit i use to run a Preventive maintenance system which cost more than the equipment being maintained unless it was a timex item i.e seals etc, 100 pecent IPA if not avalible you can still use 75 iIPA if you run it through a molecular sieve which is not avalibel from your local supermarket so the next best thing is common tabel salt.poor half a cup of tabel salt into you week IPA the sailt will not desolve,the salt will remove the water from the IPA in about 30 min draw of the IPA just above the salt 100 persent IPA the salt can then be dried out and used again.

[@ChadwickModelRailway]

Wow, what a great tip Ken. Regards Charlie

[@thegrowler-blackwoodngauge]

Another great and informative video Charlie. Agree about the problems you can come across in actually getting into a loco for maintenance. A bit more thought from the manufacturers wouldn't go amiss. Cheers Euan

[@ChadwickModelRailway]

So true Euan.

[@terryflynn8830]

Another interesting video. My experience with lubrication of model trains is you can do as much damage over lubricating as you do not lubricating a model. Modern models use plastics designed for bearings and gears that need no lubrication, so for plastic gears no lubrication is required, irrespective of what the instructions say. Small electric motors have pre lubricated sintered bearings an will normally last the life of the motor brushes. Motor carbon brushes can be softened by excessive oil and the carbon oil dust mix can cause the motor to short out. On the other hand, metal bearing require lubrication, and will wear out if left to dry out. The worm bearings on top of gearboxs should be checked, as these wear quicker than metal main axle bearings. On steam locomotives my experience is the siderods wear out first if left dry. My prefered product to lubricate side rods is graphite grease. Graphite grease is electrically conductive and shold not be used for anything else except lubricating electrical pick up wipers on the backs of wheels.

[@ChadwickModelRailway]

Some sound advice there Terry, many thanks. Regards, Charlie

[@DJ_K666]

Hi Charlie. One thing I noticed was how encased the worm gears on the class 25 are. Maybe the manufacturers ought to have put an access hole in so that the worm drive is accessible through the side of the plastic casing rather than having to poke it in at the ends like you did there. Ditto for the Hymek, the gears train is right inside the bogie so maybe a hatch that the nozzle or needle might go through would be useful.

[@ChadwickModelRailway]

I’m sure that you’re right, they might propose a maintenance regime, but it’s very hard to carry out. Regards Charlie

[@pgcroc8484]

Another god one Charlie. Yes, track cleaning video would be great. I use guitar plectrums, (picks), to prise locos apart. You can get very thin ones, (0.71 mm), and they are all chamfered so no hard edges. Plus they come in pretty colours! Pete

Great suggestion Pete, I'll look into getting some. Regards Charlie

[@ChadwickModelRailway]

It's a nightmare Alastair.

[@ThePeejRR]

The accessibility to the gears of modern model locos is a pet peeve of mine. Older locos you just popped the shell off and there is it's guts for all to see. Now a days you pop the shell off (if you can figure out how) and it's chocked full of stuff and the actual moving parts are hidden away under weights and/or cowling. Infuriating... I suspect it's mostly done to void your warranty if they see you've moved anything when you inevitably send it back for a fix. Another great informative video Charlie, good job!

[@ChadwickModelRailway]

I’m so pleased that you enjoyed the video, and you’re on my side regarding manufacturers!

[@chriscohlmeyer4735]

Chadwick Model Railway yes, it seems that the manufacturers prepare the "oiling diagram" without speakers and DCC chip then expect you to figure out how to "oil and grease" without removing the extra bits. Too late for the older locos but new ones should plan for cleaning and lubrication even if it is a few more screws or tabs and warnings on the instructions.

[@paulbeard49]

Hi Charlie, very informative. Spare a thought for us poor N Gaugers, all the problems you encountered are far greater, the locos are even more delicate. Something does not go as easy as it should and suddenly your careful handling goes out of the window while you concentrate on the problem in hand and serous damage can occur.

[@ChadwickModelRailway]

So very true. I regularly break stuff even when trying to be careful. For you guys Paul, it must be dreadful.

[@jimmydotcom6078]

Very informative as ever Mr C.. luckily I refrained from using some light glue .. !! Re servicing, it is surely vital that owners can get into the locos, and it's not impressive when when we can't.. the Hornby standard diesel shunter has 2 plastic clips to take the cab off the chassis and away from engine cover.. have wrecked 3 such locos now!! Hidden bluetack helps...!

[@ChadwickModelRailway]

Yes it’s a shocking situation Jimmy.

[@nigelduckworth4419]

I have 11 locos (only sadly) but they are all run regularly to a timetable for 5 months each year. Some, Airfix, Hornby and Mainline were purchased in the early 80s, used for a year and then put away until 2018. Some new ones have been purchased after that date. The old ones were serviced by me in 2018 before being converted to DCC. Since then they have never has a service except an annual oiling, since they are all steam. All except 2 are hard wired and so servicing is a particular pain. They all still run perfectly after 5 years and I do not intend to service them until they start to misbehave. I have been worrying about the lack of servicing but no longer thanks to your video.

[@ChadwickModelRailway]

That sounds like a good reliable strategy Nigel. Have a great Christmas, regards, Charlie

But does the oil in the grease dry out over that time, perhaps if it’s in a warm environment it might?

I did find it very useful to put a small Neodym-Magnet on my screwdriver (near the handle, so it is out of the way). It helps pulling out the screws, and of course putting them back in.

[@ChadwickModelRailway]

What a cracking idea Andreas.

[@gibsonethirty2836]

Not trying to be a smart arse but you are aware that one can magnetise any steel screwdriver to do this permanently! Get that magnet and in one smooth motion rub it down the full length of the metal shaft of the screw driver (steady now, no silly comments! :D ). Now lift the magnet clean off the screwdriver at the end of the motion. Do NOT under any circumstances rub it back up the shaft the opposite way! Now comes the tricky bit, with out letting the magnet slam into/onto the shaft, connect it at the top again exactly the way you did at the beginning (North - South as before of the magnet), and draw it back down the shaft like you did the first time. Repeat this at least 10-20 times until the magnetic field in the screwdriver is strong enough to pick up and hold any screw sizes your inclined to be using with said screwdriver. When this effect starts to wear off (many months to years later depending on treatment of screwdriver) just reapply like you did the first time. Things that will effect the induced magnetic field are, dropping it/slamming it into onto things, throwing it into a tool box full of other metallic bits an bobs, placing it next to any magnetic fields stronger than that induced into the screwdriver...... you get the picture, look after it.

@@gibsonethirty2836 Yes, of course, I know that, I'm an electrician. But I'm also a bone-lazy guy. When I want to get a screw out, then I want it now.

Yet another good little film. Something of interest for you is something you may of may or not know is that in the factory where Bachmann model locomotives are assembled they grease the cogs and sprockets which is fine. But quite often on some of the Bachmann steam locomotives they over do it with the greasing lead to locomotives not preforming as well as they should. I was told this years and years ago and not long after I brought a Bachmann steam locomotive snd it did not preform very well so someone from the model railway society I used to belong to offered to take my loco away and remove the grease and then oil it instead. When I got my locomotive back I found it worked a lot lot better. I haven't had any trouble with any other Bachmann locomotives I have brought since wich I am glad but my friend who is in the know said it would be wise to remove the grease on all my Bachmann steam locomotives and oil them instead which I have not got around to do but I will one day.

I've now watched all 109 videos over the last two weeks in their entirety, yes, even the hand sanitiser ones! I have learned so much, and though my chosen gauge is 'N' gauge, most of the content can be applied to my basic modelling skills which have no doubt benefitted from this superb channel. As for DCC, I was never a fan of the sound as I thought it was always too quiet, especially in 'N' gauge but I appreciate all the extras and especially the computer integration with block control. I think the manufacturers have missed a trick with DCC sound. Last year, I visited the Hornby centre down in Margate and met the CEO (sorry, forgot his name) and mentioned an idea I had. His reaction was one of interest, and it would not surprise me to see my idea come to fruition in the next few years. As for the idea, well I'm keeping that to myself for now as it may well be the 'next big thing' ???

Then washed the grease away with methelated spirit. Then put a dab of light grease on the gears and oiled any bearing etc. with Singer sewing machine oil.

So that's what business cards are good for. I will use that tip. Also there's a developing conversation about track cleaning products used. Some like alcohol actually work against keep track clean over time. Gleaming seems to be becoming a way to take out fine scratches . I have noticed over the years that new track seems to stay cleaner until I used a "bright boy" track cleaner. Then I had to clean more often. More investigation needed. Years ago on my DC layout "Wahl" hair clipper oil saved my layout. It even worked on brass rail so we didn't have to clean as often. Hummm!

Hi Charlie, Another informative video. One thing worth mentioning when refitting locomotive bodies is best practice when refitting the self tapping screws into plastic, you should always slowly back the screw up until you feel it drop into the thread that's been cut other wise you can cut another thread.

Hi Charlie. Such a useful video - many, many thanks. By pure coincidence today I unpacked a Bachmann Class 25 which I'd bought at auction last month so it was good to see how you serviced it. Especially as mine is an earlier incarnation, without DCC/sound and with no notes about how to service it on the exploded diagram of parts. I think mine (D5211) was produced in 2007. It has an extra equipment box modelled below the underframe taking up all the space where yours has a gap; I presume this represents an earlier prototype.

Hello again Charlie. Another great video. My layout is an end to end gwr branch layout so my locomotives only run for short periods of time. All my locomotives are bachmann steam. The problem I have found is that it's not a good idea to lubricate the motor bearing at the commutator end of the motor. It does not matter if you use a minute drop of fine lubricant or gear oil (applied using a pin) the commutator always gets contaminated causing arking and smoke. I then have to remove the motor and soak it in isopropyl alcohol, let it dry and clean the slots in the commutator. The cleaning of the commutator is a real pain as you can't see inside the end of motor. Some of my locomotives are 15 years old and still have the original motor and brushes and still perform well on my gaugemaster contoller on my dc layout. I say if it's not broken then don't fix it. As usual another superb and informative video. Stay safe and keep well. Cheers Chris.

Hi Charlie nice to see you back at Chadwick another informative video of how to service our locos the amount of time we do this task to keep our trains in tip top condition it’s like doing an apprenticeship at crewe works I did something similar to my class 43 midland mainline hst ringfield motor that is now dcc fitted the grease from woodland scenics is a handy maintenance tool to have as well as the light oil where do you buy your cleaning alcohol from finally I have got trains running again at Beighton Parkway that used to be in my loft but after my knee replacement loft ladders are abit tricky so I have set up a layout in my shed I would like to thank you for all the inspiration from your great videos talking about and sharing your experiences to help modellers like myself and others to create our great hobby as I said to my wife it’s not just toy trains it’s a combination of computers,electronics and trains keep making these great videos Charlie. Kind Regards Kev (Beighton Parkway) Sheffield

What a heartwarming comment Kev, many thanks, regards Charlie

[@paulrivitt7728]

27:38 Missed one! Thanks Charlie. Another thoroughly informative video. Yes, I'm a "if it ain't broke..." guy. But in my line of work I do do preventive maintenance on industrial machines and am mindful of the risk of making things worse. The Hymek has a well thought-out serviceability, which appeals to me, which shows in the running tests. For the slower result of the 25 I'd suggest that metal gears are more "sticky" than nylon ones - the excess grease that you wiped away was not needed anyway - I doubt there was no grease at all on the gears, just enough for wear protection purposes. The new grease just bunged it up again. Obviously if you reduce the speed of the Hymek to match the original lap time then the current will be lower indicting the effectiveness of the wheel cleaning (would have been interesting to separate the effects of greasing and oiling but hind sightedness is 20-20). I am into steam but you are starting to call me over to the D side. Cheers Paul

[@ChadwickModelRailway]

What a great comment Paul. Yes the whole dilemma of loco servicing is a nightmare! Regards Charlie

[@SteveS3667]

Hi Charlie, I had my N Gauge 40141 die on me couple of months ago, bought it in Sept 2018 off ebay for £279 so naturally was devastated, It was a DCC sound version, sent it to a friend "Deltic Napier" and it was the motor, he replaced the motor and it now runs better than it did before.

[@ChadwickModelRailway]

Please reply in a new comment Steve, but I’d like to know how many hours it had run before the motor burnt out, regards Charlie

[@terrycharleslewis7565]

Great vid Charlie, I've two Gaugemaster wheel cleaners that just sit on the track, put the power through then sit the loco on top of the wire brushes, really simple. Regards Terry

[@ChadwickModelRailway]

I have them too Terry. They scratch the wheels clean which promotes more carbon built up.

[@Poliss95]

Re the IPA with 30% water. I don't know if it means, but when I worked in the pharmaceutical industry we used to dry the stainless steel vessels with alcohol on the principal that alcohol makes water evaporate very quickly. The alcohol we used had an ingredient that stopped you drinking it. Without that additive Customs & Excise would charge duty on it.

[@ChadwickModelRailway]

That sounds highly likely mate.

Always important to clean the contacts to wheels for reliable running and sound.

[@mysticrailroad]

@@ChadwickModelRailway and by the way i had to look up "taking the mickey"- never heard that one. i'm learning all kinds of useful British phrases from your channel! ("top shelf" was my fave lol)

[@tomlawton7087]

Charlie, most entertaining. When using the superglue, I note you pour out some and then reach across that to work on the loco; as a matter of process, it seems better to have the glue beyond your normal reach! For alcohol, the free ions are only released when there is water present (like soap); hence an amount of water is needed to make the magic work! Four cleaning functions; the chemical route splits into two, for surfactant and for solvent. Surfactants allow polar solvents (like water) to be effective (as soap removing oil and grease). Solvents dissolve the item directly (like petrol dissolving grease until it is so runny that you can wipe it off). When you remove the excess grease from the end of the worm, the best place to put that grease is back onto the worm, within the working area of that worm's thread. For the contacts inside the bodyshell, using contact cleaner and contact grease ensures the contact area is clean and maintains contact. I like the idea of inverting the rolling road with books; cheaper than the commercial versions, and potentially more learned! The Hymek does show the pickups more clearly, so allows these to be cleaned before reassembly; again, you might want to clean the wheels inside before stripping down, so the contacts are then put back into a clean environment. All a matter of how dirty the system is! BTW, when we first saw the Atlantic, it was sparking as it paused; it appears the rear axle of the front bogie was causing the momentary short, which paused the operation. (Not sure why the running-in would improve that, but...) Thanks for the entertainment!

[@ChadwickModelRailway]

Hi Tom, The Atlantic was a complete nightmare and the sparking soon disappeared without trace. I'm pleased that you found the inverted rolling road interesting. I've been told that a commercial adapter is available for this. Regards Charlie

[@tomlawton7087]

Charlie, Yes, James lists the inverted rolling road. (www.dcctrainautomation.co.uk/marrion-zeller-upside-down-system-kurt-h0.html). There is a KZbin clip that shows the use, with elastic bands to hold the loco against the rolling road. Obviously pony trucks, etc, are not supported, but they don’t need the rolling road. kzbin.info/www/bejne/rXndYYqbZ5uAe6M is the KZbin clip; it’s in German, but you get the gist by watching the pictures.

[@ericcraig8205]

Ive been thinking about this,ouch but i am intending to add the current and voltage gadgit you have from DCC. The trick i guess is to document,you like that kind of thing,the current draw of each of your locos once run in and keep a log,if its climbing over time then somethings going awry and needs a deek into,but other than keeping the track clean you have the job covered with you having a constant view off current with your concepts gauge on the job.

[@ChadwickModelRailway]

Great idea Eric, we love our documentation.

[@frankhellman6879]

Great advice. One more thing about disassembly/assembly tools. Please no "special" tools. K.I.S.S. My guess is that PECO employees don't maintain locos because the company pays for new ones. We don't have that luxury. And last but not least, maintenance too often, and too much lube, is worse than no maintenance at all. Always nice to see your vids!

So, surprise, even in H0 you have to service your Trains once in a while... especially when they where hidden in teh attic for about 12 years. Turns out that prying open the gearbox on the Mehano Thalys PBKA can lead to a broken off Coupling... - and no chance of repair on that one. luckily i found the same trainset with a faulty motor for just over 20 euros (including shipping). Now I have spear parts for some things if i manage to break them again. cheers, Sarah

[@ChadwickModelRailway]

Yes Sarah, maintenance is a nightmare.

[@stephennelmes5246]

Hi Charlie very informative video, I had never thought of using the rolling road upside down to clean wheels so will definitely try that. When I remove screws from anywhere on a loco I pop a neodymium magnet on the screwdriver shaft and the screw will stick and can be withdrawn. Also makes putting them back in simple as you can stick the screw on the end of the screwdriver and easily guide it through fixing holes.

[@ChadwickModelRailway]

What a fascinating tip Stephen. I must confess I have never heard of putting a magnet against the screwdriver in that fashion. Regards Charlie

[@gibsonethirty2836]

Not trying to be a smart arse but you are aware that one can magnetise any steel screwdriver to do this permanently! Get that magnet and in one smooth motion rub it down the full length of the metal shaft of the screw driver (steady now, no silly comments! :D ). Now lift the magnet clean off the screwdriver at the end of the motion. Do NOT under any circumstances rub it back up the shaft the opposite way! Now comes the tricky bit, with out letting the magnet slam into/onto the shaft, connect it at the top again exactly the way you did at the beginning (North - South as before of the magnet), and draw it back down the shaft like you did the first time. Repeat this at least 10-20 times until the magnetic field in the screwdriver is strong enough to pick up and hold any screw sizes your inclined to be using with said screwdriver. When this effect starts to wear off (many months to years later depending on treatment of screwdriver) just reapply like you did the first time. Things that will effect the induced magnetic field are, dropping it/slamming it into onto things, throwing it into a tool box full of other metallic bits an bobs, placing it next to any magnetic fields stronger than that induced into the screwdriver...... you get the picture, look after it.

[@christopherbarton6770]

Keeping up the high standard - excellent. Just thought to mention that you should have put the cap back on the Roket and put it in the fridge to stop it going off. Also Hob-e-Lube gear oil is available separately - it is the only one of the seven in the pack that I use. Model Rail had an article some two or three years ago on lubricants and cleaners which I found very useful. Thank you - I look forward to the next video.

[@ChadwickModelRailway]

Christopher I'm so pleased that you found the video useful. Regards Charlie

[@gibsonethirty2836]

G'Day Charlie. I always give your video's a thumbs up matey! :D Over the years I have found that using grease and oils in our Loco's/rolling stock leads to a gunk build up that will eventually cause some serious issues with our Loco's/rolling stock. As your quite aware its because the lubricants we use are wet and sticky by nature. So I have stopped using them altogether. Instead I now use a dry lubricate - Graphite Powder. In fact its the same stuff that Kadee use for their couplers. Works a treat on all moving parts and is not a dirt magnet. All you need is a little puff of powder onto any moving surface and your good to go. Lasts an incredible amount of time between applications, the only down side is it can get everywhere and make for dark smudges if your not careful. As to getting items clean before re-lubricating, I use contact cleaner in a spray can and blast the crud right off.

[@ChadwickModelRailway]

Great comment G130, but what are you using as your contact cleaner?

[@gibsonethirty2836]

I have learnt over time to be cautious oiling connecting rods - especially if the retaining lugs are a friction fit. Very light oil can penetrate into the friction fit socket and the retaining lug loosens and will not stay inserted. N scale in particular. Screws can come loose as well but they can be cleaned and put back. Have you had any experience with Labelle lubricants? They have a lubricating powder which looks interesting (Labelle 134). I for once would be interested in seeing a comparative video on lubricants. Thanks for all the great videos - I always enjoy them.

Great video Charlie. Had to take apart my only two non-running n-gauge trains, painful to do. So much dust, fluff and gunk inside. One of them is still in pieces as the wires were so old between the tender and engine they crumbled. Waiting on parts to finish the repair, terrified of destroying the locomotive with my soldering iron. The foam mat is not something I thought of, had to hunt for springs and screws that bounced away. Will be investing in one! And that rolling road, so useful.

HI Charlie, whatever you do when carrying out maintenance on your locos make sure before putting the body shell back on the chassis, that there is no super glue on hands after using it. I,not so long ago, got super glue on my thumb when putting a class 33 body shell on to its chassis and the result was nasty un-removable glue stain. The air will turn blue with a vocabulary of swear words.(I speak from experience) Enjoy watching your videos,5*.

[@raymondsommerfeldt769]

A really good, informative video. Is the class 25 a Bachmann loco? It looked likely the way the loco is\was over lubricated. There's a line of products from a company called Aerocar Products that I've used with really good results. I don't know if they're available in the UK, but it might be worth your while to try them if you can find them. Also, if or when you do a track cleaning video, you might want to try rubbing your track with a graphite stick after you clean it. This helps keep the rails clean longer and improves the electrical contact between the rails and the loco wheels, assuming that the wheels are as clean as the rails.

[@ChadwickModelRailway]

Interesting points Raymond, and I will certainly be mentioning graphite.
