Hornby Dublo Class 28 Co-Bo : Repair Request

[@stephendavies6949]

Always been fascinated by the Co-Bo. Great to see one being brought back to life with those healing hands of yours.

[@richardc674]

Thanks for this Bill. I have the three rail version of this loco, it has the running number D5713 and different contact arrangements, but otherwise appears identical. I have had mine for over 50 years so it is probably overdue a service so very pleased to see this instructional video! I don't have any 3 rail track laid at the moment, so I can't run it but it does still work with a 9 volt battery across the wheels. It is Hornby Doublo model number 3233, it was bought from Beatties of London for a sale price of 15/- probably around 1965. On the box it claims to be fitted with a "ring field peak-power motor"

These old models are so well engineered - no plastic seems to have been used n the important parts of the mechanism, no plastic clips ready to break off! Joy of joys. Well done Bill and thanks fo the video.

[@callumk5]

So satisfying to see all the clean parts going back together. If you squint a bit she could have been hauling the Condor again. She’s definitely outlasted the prototype!

[@stuartburton1167]

The loco body amplifies the sound. You can add foam to deaden the sound a bit I used dishwashing sponges cut to size and glued in place with spots of Black Tack which is a very tacky version of the familiar Blutack.

[@ScreamingLordStokes]

Great video. I love the quirky character of the CoBo with its sad face and unconventional wheel arrangement. It looks good pulling the grain wagons Bill - you'll have to model a distillery on your layout! 😊

[@NTSCuser]

For added authenticity he should sample some their output while running the wagons.😉

[@BanterousEngines]

It’s BoCo! (it literally is, that’s his exact number in the Railway Series) Great video!

[@johndrew3202]

Very interesting Bill. I don't have any of those but I admire your ability to take them apart and rebuild them in much better state. Thanks for you work and good to see it running again.

[@7649angel]

Nice one Bill! I love those old Hornby locos.

[@shedhead00]

Bill, ultrasonic cleaning is marvelous, I bought mine stainless steel but made sure that the internal dimensions were suitable in size for loco bodies .

[@TheDaf95xf]

Great lease of life for such an old loco 00Bill 👏🏻

[@roberthocking9138]

You will love an ultrasonic cleaner bill. I’ve got a 10L one, it’s stainless steel, works extremely well, but holds a lot of fluid, if I had my time again I would buy a 5L model. The smaller plastic ones are no good, only meant for cleaning jewellery and as you said they fall apart. Another nice job 👍

[@petersmith4455]

hi Bill. had one of these locos in 1962 as a child, it never ran great then, hence my dad bought me a Triang Railways train set, had no problem with it, great days back then

[@eddierools]

Very interesting model you worked on here, it's certainly crazy to think that these old Dublo models and the SIlver Fox resin kit were for a good time the only options we had for a Class 28 in this scale, at least until we got the Hattons/Heljan model 12 years ago. All in all, very nicely done on this repair Bill!

[@modelrailroader5619]

Something a little different, awesome! Thanks for sharing, Bill.🇨🇦

[@guyclark2975]

It's fascinating to see you working on these old models. They have character, Quality and pretty much bomb proof unlike the models of today. Yes the modern super detail models are impressive but nothing beats an old Dublo or Wrenn.

[@johnstephens649]

Got to see you working on another Dublo loco. Really got to pluck up the courage and service my old “deltic.” As for being noisy, great. Bet the real thing was too!

[@roberthill6216]

And smokey!

[@viking1236]

I use an ultrasonic cleaner for rifle cartridges and it does a pretty good job. It’s a Lyman and I got it from my local firearms dealer along with some cleaning fluids for different metals . Not particularly cheap but it works, struggles with black powder stains but that’s hardly likely to be an issue for you! Edit Keith Appleton has one for is miniature steam engine parts and has a few videos on his KZbin channel and website.

[@lesbird2074]

Many years ago, Hornby Dublo used an advertisement to demonstrate the power of their locomotives by showing a few Co-Bo's pulling a trolley with a young lady sitting on it. I can't remember off hand how many they coupled together for this feat. I still have one of these which I use regularly to pull a track cleaning wagon. Every other locomotive I have has a problem pulling it!

[@MickCampin-jp9kb]

It was only one class 28 with a small child on a special track. I've got the catalogue I think it was no 5. I will look the catalogue out and confirm when I can.

[@ChobertonJunction]

Great to see old stock given a new lease of life.

[@playpaulbee]

A former colleague of mine used an ultrasonic type jewlery cleaner for getting the gunk off Shure microphone grilles, seemed to work pretty well.

[@MrJayb988]

This is the exact model of locomotive that boco from Thomas is based on this model even has the same running number that boco has in the original series.

[@stillstanding123]

I really love this old loco, so worthwile preserving. Also good to see the close up shots at the end, keep these coming 😊

[@MickCampin-jp9kb]

Mine also growls but then again it always has growled since day one but it runs well.

[@harrygleed423]

Bill another wonderful repair on a beautiful old loco. I love the old loco they sound proper model trains. Could you work on my car😄😄

[@keithwreyford999]

I have to agree with Stuart that the crood mechanism, together with a metal body, is the main problem over the running noise. It's still very interesting to watch

[@Mike-kc8rl]

I love these old Hornby dublo locomotives! Had a co bo for about fifty years and still runs great! There is also a wonderful selection of aftermarket spares for them! They are also getting very good value used now as it seems the market has fallen off on them? Made in Britain! That makes them worth buying alone?

[@peterm7548]

What a weird loco! It looks like half a Bo-Bo and half a Co-Co welded together! Never understood the logic behind the Class 28. But a great model.

[@johnmiller-pb8ne]

thanks for the video very enlightening regretfully mine will go into reverse any thoughts please

[@tankmicr00man]

In the Hornby Railway Collectors Guide, it dates to 1966! R2233, only made as class 28 type 2 for one year. Wow, great improvement on this one Bill!

[@MickCampin-jp9kb]

It came in a freight set with a couple of wagons and a brake van with a circle of track. I've still got mine in its box.

[@keithfisk5641]

The Co-Bo came on the market in December 1961. Hornby Dublo went bust and was taken over by Lines Brothers late 1964. The Co-Bo and a few other Hornby Dublo locos survived a little longer being listed in the Tri-ang-Hornby catalogue while Tri-ang tried to sell off the large stockpile of unsold Hornby Dublo locos. My brother was given one of these Co-Bos about 1963 and it is still a runner today well outlasting his comparatively cheaply made Tri-ang locos of the same era.

[@robinforrest7680]

Nice! Good diesely sound too 😂

[@nicholasbishop3300]

Well done Bill Nick Australia

[@ModelRailwayShed]

Nice one Bill

[@ThewhiteE12]

The class 28 Has The Same number as the Thomas character:Boco

[@User-3O3]

It's Bo-Co. :)

[@Cthulhu1970]

It is indeed. It even carries the correct number. :)

[@MickCampin-jp9kb]

I've got one of those Hornby Dublo class 28. It was the worst selling model Hornby Dublo ever made

[@peternorris6438]

Running well if but a bit noisy

[@nevillepowell7502]

Off topic but you were talking of automatic train operations without dcc,I can reccomend a new system! I watched the demo layout recently at an exhibition,do watch this video"" Fascinating invention,Automatic analogue model railway"

[@NTSCuser]

I'm baffled as to why a die-cast locomotive would need traction tyres?

[@sanspareil3018]

I dont know if you are familiar with these old Dublo locos but that particular motor bogie is extremely powerfull and when introduced in the early 60s two models fitted with these bogies hauled a small child on a trolley as a publicity stunt. Another stunt showed one of these bogies fitted to aloco pulling 28 Dublo coaches which dont roll anywhere near as freely as modern 00 coaches. So the traction tyres were a way of transmitting the ample power of these bogies to the track. Another reason is that the wheels on these models had a shiny nickel surface to improve electrical contact so there was very little “grip” from the wheels

[@rhiwderinraytube]

Just like the original - noisy and unreliable!

[@brucebigglesworth9532]

At least the windows didn't fall out of the model.
