    This comes with the Kiel to Lubeck route which I picked up in the recent sale bundle. Can anyone say whether the physics are accurate, as although we are used to DMUs not having accurate performance this unit seems to take it to the extreme. Put it in Notch 1 and it accelerates to 17 km/h and sticks there. Each subsequent increase of the throttle simply adds a few more km/h to the top speed, there is no progressive or analogue effect whatsover. Haven’t tested it up or downhill yet but wouldn’t be surprised if the speed cap continues to apply, i.e. coasting downhill at 80 km/h put the power in Notch 1 and the train would slow to the capped speed.

    Sorry, I don't know it - is this an electric train? I know many EMUS have Notch 1 as "shunt" - basically suitable to get you going slowly, and you have to move to Notch 2 - series to accelerate further, then parallel, WF.

    It’s a DMU...

    You would be better asking on a German forum as the people there would know how realistic on not the performance is
    Try Railsim.de
    If the performance is wrong somebody might have done a patch

    Or I might try and sub with the 218 and Dostos.

    I suppose that is easier than asking a question where somebody has a better chance of knowing an answer

    I asked a question in english as I needed to find something out - no problem at all

    Pegnitztalbahn BR648 seems to have two gears, switch at about 24.5km/h.
    After accelerating to 25, move "Power Handle" to Notch 1, otherwise train will accelerate crazily.
    Does it work like reality?

    I don't know about the physics themselves although if I'm thinking of the correct train, it is incorrectly set up as a diesel electric rather than a diesel hydraulic. I can't say for certain is the 648 (and if the Lubeck to Kiel version has the same error) but around that time DTG did get some flack for doing that on a German DMU.
