    When buying a car, people always look at the engine size and other specifications as this can dictate insurance group and fuel efficiency and other things, but it is not so widely talked about with trains. The engineer in me was curious about the engine sizes and other specs. of the diesel engines in passenger trains so I have made this list from info I remember and have found on the internet. Please add to it, and I hope you find it interesting. If anyone know anything about things I have marked with question marks then that would be great :D

    Locomotives

    37 - English Electric V12 ???

    43 (HST) - MTU 4000 V16 or Paxman VP185 V12 ???

    47 - Sulzer V12 ???

    57 - 2,750hp EMD 645 126.8L V12 2-stroke turbodiesel

    67 - 3,300hp EMD 710 139.6L V12 2-stroke turbodiesel

    Multiple Units

    142/143/144 - 225hp Cummins LTA10-R 10L straight-6 4-stroke turbodiesel (per carriage)

    150/153/155/156 - 285hp Cummins NT855R5 14L straight-6 4-stroke turbodiesel (per carriage)

    158/159 - 350hp Cummins NTA855R1/400hp Cummins NTA855R3 14L straight-6 4-stroke turbodiesel or 350hp Perkins 2006-TWH ??? (per carriage)

    165/166 - 350hp Perkins 2006-TWH ??? (per carriage)

    168/170/171 - 422hp MTU 6R 183 TD 11L straight-6 4-stroke turbodiesel (per carriage)

    172 - 485hp MTU 6H1800R83 ??? (per carriage)

    175 - 450hp Cummins N14 14L straight-6 4-stroke turbodiesel (per carriage)

    180/185/220/221/222 - 750hp Cummins QSK19 19L straight-6 4-stroke turbodiesel (per carriage)

    (Note: I have only included passenger trains (i.e. no 57/0s), and have not included things with non-standard engines (i.e. 57601, a very few ScotRail 170s)

    It is interesting to note that despite the massively different power outputs, Classes 150/153/155/156/158*/159/175 all effectively have the same engines, Cummins N-series 14 litre engines.

    (*Not counting the Perkins-engined 158s)

    Displacement: 4811 cu in (78.9 l)
    Compression ratio: 13:1
    Idling speed 750 R.P.M.
    Maximum speed 1500 R.P.M.
    Piston speed @1500rpm: 2125 ft/min (10.8 m/s)
    Maximum H.P. 2250 at maximum R.P.M.
    Overspeed trip operates at 1700 R.P.M. approximately

    Direction of rotation Clockwise looking on free end
    Firing Order: A1, B6, A5, B2, A3, B4, A6, B1, A2, B5, A4, B3
    Valve Settings: Inlet open - close 60° B.T.D.C. - 45° A.B.D.C.
    Exhaust open - close 65° B.B.D.C. - 60° A.T.D.C.
    Valve Tappet Settings: 0.005” 0.127 mm (cold)
    Injection Timing: 23° B.T.D.C. (nominal)
    Timed on No. 6 cylinder A bank
    Timed on No. 6 cylinder B bank
    Injector - C.A.V.: Pressure setting 4000 P.S.I. (288 kg/cm²)

    Engine Speeds (RPM)
    Idling 750
    Notch 1 750

    Have you tried the manufacturers websites where there is usually quite a lot of info on the specifications of engines which are still in production?

    Harder of course for the older engines which are not manufactured anymore but a search of the internet often reveals preservationist sites with lots of info. For example if you want to know about marine Deltic engines there is an American group restoring a Vietnam War MTB/Rescue/Patrol boat which has an awful lot of info. Try under "Nasty Boats".

    Does this mean that when a set is stabled at a station for long periods and they switch one power car off, that the other car is set to notch 2 to keep the lighting on in the carriages?

    IIRC one is always idling higher regardless, presumably unless you switch the ETS off. I had some sort of technical doc about it somewhere, I'll attempt to dig it up. With ETS on and both engines running the back( I think ) powercar never goes below 1k RPM irrespective of where it's throttle control is.

    Now THAT is an engine specification - the OP suggested a list of engine models!

    PS can i have one in blue?

    Really, didn't know that. Always assumed they were 2-stroke like the EMD V12s in 57s/67s. Are the Perkins and MTU engines in the DMUs listed 2-stroke or 4-stroke?
    I will update the list.

    Adam :D

    4 stroke. I think I am correct in saying that the only 2-strokes are the EMD engines.

    Thanks :D

    You don't happen to know the total displacement of the MTU engine in a 172 or the Perkins engine in a 158/165/166 do you?

    37s were/are powered by an EE 12CSVT (12 cylinders, intercooled, turbocharged, V-formation, Traction use)
    Based on the specs I've been able to find of a 10" bore by 12" stroke, I reckon its about a 185 litre displacement.

    About right. The 16CSVT in the 50's is 247 litres

    May seem like an idiot, but is this for an actual class and if so which one?
