    scott#5725 thank you. I think I might be expecting every run to be a flat out one. I couldn't see any trains further up the line anywhere and it was perplexing me and wasn't sure if it was connected to above.

    More recent update on this situation is that if you are using DB BR406 from Schnellfahrstrecke Köln-Aachen on this route you are stuck to 200 kmh instead of line speed 250-280 kmh.

    I just finished one run each with the 401 and the 403, and each got (briefly) 280 km/h limits

    Some services in timetable mode are limited in max speed, as irl, they are run by other types of ICE, that can't run that fast.

    Did they ever announce a resolution for this? I was running ICE 537/782 north (BR403) and having the same issue even after restarting and using clear weather conditions. Seems inconsistent as previously pointed out as the southbound service had no issues. This is the first time I've seen the issue, even though I have ran this route multiple times since the OP.

    Any information on how this is proceeding ?
    it’s been 6 months since this thread came about.

    I have not have this problem (except, obviously, 101-hauled ICs are limited to 200). There are however occasions where the limit is somewhat less than line speed- which may well be a scheduling matter. (It's a waste of fuel to rush down the line at 280 and then wait for half an hour). It's also my understanding that the speed is dropped across certain bridges and viaducts because of crosswind issues.

    I think the speed drop is for other than ICE1 only due to weight, I could be wrong on that

    I still think you should be operating at what’s done In reality, as far as I know on what reality is, is that it’s 280km since sometime after the Eschede Disaster. I’ve heard this caused the speed to be temporarily reduced to 250km before rising back to 280km, I’ve seen no further info it’s back down to 250km.

    I’m not sure whether the schedule is real or if it’s one of the routes where the timetable is only correct for start stop, which if that’s the case then the timetable would have been calculated wrong if the issue of 250km has caused an extended length timetable

    from what I’ve seen of this issue the problem is with LZB as the route seems to recognise the 280km speed but LZB locks down to 250km

    For anyone who's interested how it works IRL and how the LZB "knows" how fast the train can go, check this german Zusi 3 tutorial video.

    At least with 401s I frequently get 280- although only rarely does the train have time to accelerate all the way up to it before another reduction)

    I have a similar problem on one if the IC services. There is one IC Service driving at night (without the autorack car) that is limited to 160km/h instead of 200km/h. Clear track of course as the problem with those night services is still present so you have almost none AI traffic anyway.

    There are a few reasons why LZB might be restricted:
    For ICE:
    - The train you drive uses a different ICE type irl, which is not allowed to run as fast. (Like ICE1 standing in for ICE4)
    - wind speeds. If it is too windy, speed is restricted on several bridges like irl

    For Night-IC:
    - speed is restricted due to freight trains on the line. They are not allowed to pass other trains in tunnels, if they are faster than 160. To reduce this issue, and due to being able to better fit, passenger trains are usually limited to max 160 km/h during these times
