    Hello everyone, I have a question about the classic BR101s. They lose power when reaching 200km/h, and it's very difficult to do so. It happened to me with a Steam Workshop scenario. Is there a solution?

    Thanks

    The loco is limited to 200km/h.... Thats his maximum top speed i dont know why you should be faster?!

    I wanted to say that I can reach 200, but it struggles to reach them, it stops very often at 194km/h, while with others as soon as I accelerate I reach 200 at a speed

    Just the way the model is made to cut power to stop it exceeding 200kph.

    Try a run with the AFB turned off - that might make a difference

    AFB is off, surely the author of the scenario will have used this locomotive as a limit, because the other trains reach 200 quickly like the ICEs and also the DB101s

    Actually the type had a max speed of 220 km/h: https://en.wikipedia.org/wiki/DB_Class_101
    In practice they operated at max 200 since coaching stock was limited to that

    No! The safety systems does not allowed that. Only the Metropolitan trains had a higher speed (back in the days) but the LZB prevent you from running faster than 200. The train has a data input thats connected to the limited speed so under normal operation you cant

    I was talking about the game, some of us struggled to accelerate to reach 200 while others with the lever at 50% easily reach 200, but can this be adjusted?

    No only by Developers or maybe modders but i guess here is the wrong place here.

    The models are made to be realistic and different models have different characteristics.

    You are mentioning the loco is a DB 101 but is it the old Kuju model from about 2009 or a different one.
    You want to know if it can be adjusted but if we don't know which actual loco it is difficult to say.

    No matter what 101 you are driving, if you are driving the train yourself you are not allowed over 160km/h in real life.

    It’s a game and you can ofcourse disregard real life rules.

    I understand, what I mean is that the locomotive struggles to reach 200km/h while accelerating it struggles to reach 200 and as if it were held back by something, could it be the heavy consist?

    DB Class 101 are passed for and run at 200kph on a daily basis - in real life

    The consist you are pulling will make a difference
    10 coaches of one make, like Kuju, might be heaver than 10 coaches from a different maker, say RSC or VR

    Set a test run of on one of your German routes - it needs to be a fast one like Munchen - Augsburg
    Put a 101 on 10 coaches and see how long it takes to reach 200 kph
    Then swap the 101 for a different one with the same coaches and see how long that takes.

    And what loco gets to 200kph quicker - pulling how many coaches?

    Just done a test run on Munich - Augsburg with the Class 101 and coaches that come with the route
    Having cleared the 60 crossing near Augsburg Hochzoll the line speed goes to 100 then 280
    On full power I'm up to 222 kph before slowing for the 200 near Mering

    Not sure why you cannot reach 200?

    “If you are driving the train” is what i said. Above 160 you are not driving the train. The train drives itself on LZB.

    I don't think the Kuju/RSC DB 101 has LZB?
    Nothing activated in the cab.

    It doesn’t even have PZB afaik. Just some wierd very basic aws implementation masquerading as PZB. There isn’t even a brake curve.

    Anyway, driving manually on trackside signals above 160 is against regulations. For good reasons.

    Is that because German/Austrian railways are not as good as UK Railways?

    We run a lot of different trains at 125 mph/200 kph with nothing more than AWS :)

    It’s not considered safe in Germany. On heavily trafficked lines the signal blocks are too short and too plentiful. The considerations are: brake lenght and driver reaction times.

    I don’t think i’m qualified to explain what is best, i am only a guitarplayer.But what certainly is not very good, is the Kuju 101.

    Agreed - the vR version is much better

    I think you know the answer :)

    The colour signalling system in Germany is practically three aspect across main and advance: clear, warning, danger.
    On British higher speed lines you definitely have four aspect signals - the double yellows.
    Also, on British lines you can have signals further apart, whereas the German warning is considered 1.00 km ahead. Stopping from 160 in just a km is actually quite impressive and not even possible with all train weights - 160 is only allowed for agile stock (passenger in general).

    Instead of complicating Pzb with further speed signs and dynamic magnets with dynamic expectations, there is Lzb instead. In theory you can drive over Lzb manually (in-game you often have to) but real stock just does it for you. Except you can still manage throttle and brakes I guess, so it's mostly about respecting the brake curve.

    ---

    As for the OP, a lot of trains are designed in-game to fizzle out at specific speeds, whether it's supposed to be computer controlled or a simplification, no idea. Usually that's just a gradual loss of power, so the practical speed limit depends on the consist drag and the grade. You can also have an assist loco that pushes yours once above the power limit.

    Except the OP mv75 has not replied which locos are giving him the problem - he just said he had both.

    Maybe one of the RSC locos has LZB which is why it does not reach 200kmh but the old Kuju will reach 222 or faster.
