DMU Diesel Train Driver Part 2, Driving The Train

[@derrickgreen9020]

I either overshoot the station or stop 4 miles early.

[@patton303]

God bless the people who upload these glorious historic artifacts. I could watch old films like this for days. *Sometimes I do*

[@ChoppingtonOtter]

What a fascinating film. Not only for learning how they drove them, but seeing the engineering of the time and the footage of the lineside equipment, crossings etc from that time - absolutely fascinating.

[@MittyNuke1]

My thoughts exactly. What a look into the past. I think stuff like this often conveys more history than any official "history" films, since at the time this was just made as an instructional film for the people of those days, not with any intent of conveying a specific message.

[@lewisner]

I looked on Google Earth and Wickenby signalbox (13.51) still exists but the station closed in 1965 and is now a house.

[@c2757]

Start the two diesel engines up in a shed with the doors closed. Walk round and do your checks, put destination indicators right and then ring for an ambulance to get treated for carbon monoxide poisoning!

[@MrDavros-qb2lj]

Yes it must have been hell in the colder months, presumably the roller shutter doors were opened first (hopefully!). I have great memories of the class 114s in South Yorkshire. Did Skegness station have any platform seats then (1956), it certainly hadn't by 1992! Thanks for putting this series of films on.

[@neildahlgaard-sigsworth3819]

c2757 the exhausts are abot 13 ft above rail level and the sheds had good ventilation systems above the trains to remove the fumes.

[@jacquesblaque7728]

Diesels are not serious generators of carbon monoxide. You must be thinking of Otto-cycle (gasoline) engines.

[@andybray9791]

Different era

[@c2757]

@@jacquesblaque7728 From time to time I work in an ex. RAF WW2 full size aircraft hanger - say 150ft by 200 ft by 24 ft high. It's a big building. If someone starts a dmu size diesel engine up in there, as they regularly do, it becomes very unpleasant fairly quickly, even in that size of place. I will admit I put carbon-monoxide in my original comment without specifically thinking about it in detail. Regardless, being in an environment where the air is that thick with diesel fumes can't be good for the health.

[@Mercmad]

I worked on those Self Chasnging gears transmissions when serving my Apprenticeship . It didn't take much for a driver to kill one. Common problems were melting the fusible plug in the fluid flywheel from overloading in top gear. . Engine damage was caused by drivers using the trans to slow down in a hurry, going from 4th to 2nd for example. The engines we had were Fiat (Mussolinis revenge) and Leylands and the Fiats would throw conrods if over revved to any degree too often .

These old DMU always fascinated me changing gear on a train the sound and smell of the diesel in the cabin

[@paulanderson79]

I used to watch these in the mid 1980's at Slough station. Operating between London Paddington and Reading.

[@KempSimon]

I remember back in 1981 sitting behind the driver on a DMU train from Guildford through the Surrey Hills to Dorking. It was fascinating to be able to look ahead and see the lineside signals as well as the frequent changes of gradient on this hilly route. Unfortunately with the modern Class 165 units which work the North Downs line, you can't see where you're going any more!

[@lowercherty]

Interesting transmission. Pretty .uch the same concept as the Cat Powershift transmission that came out in the 50's.

[@with2ells]

I believe that the line is Lincoln-Grimsby (GCR) as it goes through Wickenby at 13:55

[@hugebartlett1884]

Using a cloth or rag was standard practice for most of the railway men,the signal box operator rarely touching levers without the cloth. The driver has to be familiar with every part of his route along the way,speed restrictions,crossings,every signal,and incidental repair or maintenance work being undertaken. A big responsibility,rarely appreciated by most of the passengers,but absolutely vital for everybody's safety.

[@thedrwatson4363]

[@DannyPRobinson]

Thanks for uploading this, it's a fascinating video. Like 055Deltic, I used to sit behind the drivers and watch (usually this was on the push'n'pull between Greenford and Ealing). This explains really well what was going on. What's obvious is that driving these isn't just a case of point and squirt... the starting procedure in particular looks really complicated.

[@andrewbutler6477]

Remember these units in the valley lines by the late 80 s they were knackered when departing stations remember the blue exhaust and the fumes but were fun to travel on with the rattles and the engine on full power traveling on the steeply graded valley routes

[@shuttlebug468]

Thankyou diesel railcar sim :) awesome game - learn how to drive exactly by watching this

[@johnsmith-be3wt]

I notice the instruction on starting a cold engine, the narrator says "don't race the engine" yet the driver does exactly the opposite... Leyland engines do require a fair bit of throttle to start, but not full revs...

[@CreatureOfTheVoid]

Most likely to protect their hands from any grease or muck or more likely just to add a bit more grip like using a tee towel on a jar lid

[@HORNEBEEDUBLO]

The engines fitted to the unit in this video are Leyland 680s.

[@DoctorBastardo]

Albions actually but renamed as Leyland B.U.T. engines. The later upgraded engines lost the Albion designation completely.

[@vikingsmb]

@@DoctorBastardo you are right, as the class 114's depicted in the film originally had 150hp leylands x2, however they were underpowered so they fitted 230hp leyland albions x2 instead which were much better.

[@arthurmatthews9321]

Common problem with these cyclic boxes was the traction bands ripping off if a driver did a racing gear change , ie changing gear with the throttle still open. You were supposed to wait a few seconds before taking power or it would cause terminal damage. Also coasting in neutral is a no no .

[@ReallyTinyShoes]

There's no mention of a clutch, yet the gears have to be selected manually.

[@ericssmith2014]

Somewhere on KZbin there's a video of tips for bus operators that talks about this same style of transmission, with its "brake bands," and the necessity of giving it a moment before pouring on the power again.

[@filianablanxart8305]

They mentioned a " Fluid Coupler " , massively oversimplified , think of it as a simplified version of a torque converter in an automatic transmission .

[@herzglass]

When the throttle is set to idle the clutch automatically disengages. railcar dot co dot uk has a great site on "DMU Technology - The Basics". If you want to know these worked percisely that is the place to go. Later models, not too soon after this film was made (1959) were basically automatic versions with hydraulic torque convertors.

[@mikecawood]

The driver using an old rag on the controls would be to prevent blistering of the skin etc., a habit from driving steam locos.

[@welshpete12]

no , that is not the reason .

[@JohnSmith-vi5pz]

I remember these trains, as the engine accelerated when pulling away there was a peculiar rasping sound from the exhausts at a certain RPM. You can't but help think that the transmission would be very efficient, I bet they do more MPG's than modern DMU's?

[@gwsrdmu5690]

we get 11mpg

@@exb.r.buckeyeman845 Claggy, though. Round about 1970, I remember a stock movement at Reading which consisted of 12 cars, all single or two-car units. It would drift into the station laying down a smokescreen across the entire western endf

Why does it say 50009 on the satchel (1:52), and 56009 above the window (1:45)?

[@PeterTOrganist]

50009 is the vehicle number of the motor car (DMBS) and 56009 is the number of the trailer (DTCL). Both form the two car set. As 50009 is the motorized vehicle I presume that that would be the more important vehicle number and the number on the satchel. What happened when units were reformed as was regular practice or if both driving vehicles were powered, I don't know!

[@neildahlgaard-sigsworth3819]

Peter Thomson there is no difference in the importance between the 2 vehicles in this set, or any other for that matter. The driving motor vehicles were given numbers in the series 50000 to 52105 (inluding the hand full of non-driving motor cars from the Trans-Pennine units), driving trailer vehicles were given nembers in the range 56000 to 56504. Intermediate trailers were numbered between 59000 and 59832. Single car units were numbered between 55000 and 55999 (including the parcels units). The pre-production units were numbered between 70000 and 79999, and the Blue Pullmans were numbered between 60090 and 60749 There were many 2-car power-twin units (ie 2 power cars) as well as 3 and 4 car units. The operation was exactly the same as shown here, but with 4 engines to worry about instead of 2. The highest number of engines a driver of a single unit would need to keep an eye on is 8 on the Trans-Pennine units.

[@c2757]

Single cars. YES. That's what we used to call them. Never heard of bubblecars until about late 1990s! Damn silly name.

[@RWL2012]

@@neildahlgaard-sigsworth3819 the 4 engines per higher powered 2-car unit was to make up for the fact that they didn't have turbos I'm guessing...?

RWL2012 correct. They were typically used on routes with steep inclines, such as in the Pennines, or on services with swingers (parcels vans attached at the end of the train).

[@paulanderson79]

A moot technical point - diesel engines do not have throttles.

[@COIcultist]

Can't argue with you, but having driven Diesel cars for years they still have an accelerator. OK Diesels are always supplied with excess air, so they don't have throttles. I thought I was a pedant and all I ever want to insist on is the difference between mass and weight.

The toolbox contained detonators, a red flag and “presspahn shields” which should used if the train was being coupled to another in an emergency while the wrong way round. (Older LT stock had different couplers each end)

[@johnnycats5157]

is it just me, or does it seem like these locomotives weren't engineered very well? 4th gear to stop? wait two seconds when switching gears or you'll wreck it? what what?

[@herzglass]

They were engineered cost effective for the time they were made in.

[@JintySteam1]

i don't understand the gears part where they show the cut away view

[@TheMrduuk]

It was on a complicated gearing described as as planet type as u chsnged gears diffetent cogs engaged to go up down gear there are pictures i guess on internet discription or get hold of a old br dmu manual

[@jammin023]

So many ways to damage the engine... yet the controls were electrical so it seems to me (from my probably naïve modern perspective) they could have designed circuits to avoid most of the potentially damaging scenarios without relying on the driver doing the right thing. For example if you can only coast in 4th gear, it could automatically engage 4th when the throttle is moved to coast, and then go back to the previously selected gear when throttle is applied. And when changing gear it could ramp down the throttle (via something like a capacitor), change gear, then ramp it up again, to save the driver having to do that step by step. But maybe this was viewed as more likely to go wrong than a well-trained driver.

[@herzglass]

Electronics at the time were very pricy and you would need quite a few of computing or measuring devices to achieve that. Way too fancy stuff for a diesel railcar at that time. The switching these levers do is pretty easy stuff, but knowing speed, revs, load and gear and making sense out of that was a bit too much to pack into those. I assume that was theoretically possible, yet not too short after that the Class 127 for example was basically completely automatic with an hydraulic torque converter, switching gears automatically depending on speed, introduced in 1959.

Having been a Locomotive Engineer (Train Driver) in the "Yewess" (U.S.) since 1988, most of which has been in Passenger Service, this is quite interesting! I first learned about vacuum braking while on a "Busman's Holiday" in Ireland in 1997 (I think they only used vacuum brakes on their sugar beet trains); I wonder if vacuum brakes were used on the Continent, or if it was just limited to the British Isles?

[@DanielsPolitics1]

Seán Thomas Bickerton My understanding is that they were very widely used, as the engineering was much easier to create vacuum rather than pressure with steam as an ejector could be driven directly by steam, while pressure would have required a seperate pump.

[@welshpete12]

The vacuum brake is not as harsh as the airbrake going in , it is more sensitive in use . It also has the advantage of starting to operate from the rear of the train, not the middle or front, so drags the train to a stand .

[@dkbmaestrorules]

The vacuum brake is essentially a thing of the UK and its sphere of influence. It was used to an extent on the Continent, but the air brake has been standard there - at least, on the standard gauge - for about 100 years now.

[@fordlandau]

Distant is just a warning for home. Pass the on distant ready to stop at on home. Home came off on approach so driver continued. Distant not a stopping signal.

[@BenDover-wu7ed]

And in English?

[@frankney8284]

There are two signals interconnected, called "home" and "distant". Think of them as a traffic light with a "RED SIGNAL AHEAD" sign you might see on some roads. When the home signal reads "stop" the distant signal will read "stop" as well, telling the engineer to be prepared to stop at the next signal, so slow down. If the train had reached the home signal while it was still at "stop" the engineer would have had to stop the train. This is actually a simple signalling system. If you want to see something more complicated there is a channel here named "Distant Signal" that has a series of instructional videos about how CSX here on the east coast does signals.

[@austinshackles549]

On the modern railway the distant is a yellow light, means next signal is at red. Same system though - and semaphores had lights for night time with coloured glass lenses to show red and green etc.

[@gwrdriver1660]

Modern colour light signalling (MAS), is not the same as semaphore. With MAS, a single yellow signal means the next signal is red. You can also have a double yellow signal before the single yellow to give a longer braking distance. With semaphore signals, they work on an absolute block system. Each signal box has an area they control which has a number of home signals (Stop signals), only ONE distant signal and ONE section signal (The boxes last signal). This area is called station limits (There may not be a station thou🤔, it could be a level crossing for example). The area from one signal box's section signal to the next signal box's first stop signal (Home), is called the block section.There can only be one train in the block section at a time (Absolute Block). If the block section is double track, then you can have two trains (One on each track, normally travelling in opposite directions). With the semaphore signal system, the big difference from MAS is that when the semaphore distant is ON (The arm is horizontal or showing yellow light. Modern distant signals in semaphore areas are often coloured light signals), it means that at least one of the signal box's stop signals is ON (stop, red). It may not be the next stop signal, it could be the section signal (That box's last signal). This means that you may have several stop signals displaying proceed (Green) before you get to the one showing stop (Red). If the distant signal is OFF (Showing green or arm up/down), it means that all of that signal box's stop signals are showing proceed (Green), so you can go all the way through that box's station limits and into the next block section. Sorry for the long reply, hope it's of interest. Cheers, Rich

Excellent Description of AB signalling, As a mainline train driver we only have a few areas of AB left most areas are now TCB. The only thing I would add is that some block sections can be divided up by the use of an Intermediate block home (IBH) Signal that always has a related distant signal.

Takes me back to 1975 when, for a few weeks, I also used to sit behind the driver on the "pushmi-pullyu" between Greenford and Ealing (Broadway).

Tbh there's far too much a driver needs to do to restart. No one should be crawling around under a train twisting knobs and pushing buttons other than in the cab. Poor design.

That was only when full preparation needs to be done, ie on depot at start of the day's turns or if left stabled for several hours during the day in a platform or yard. Otherwise, control system air pressure is sufficient (75PSI) for the cab controls to work.

That gearbox mechanism is also used in automatic gearbox on a car nowadays.
