Good evening,
Firstly, congratulations to Hyronymus and co for a truly superb train set. I have loved playing with this, and I find that, when combined with the Dutch station set and a suitably flat (!) landscape, my games have a real Dutch flavour to them when I use the Dutch train set. See screenshot at the bottom for an example!
A couple of questions regarding this set though.
1. Why is the ICE-3 restricted to a maximum speed of 220kph? Is this the maximum it can go in the Netherlands? If so, I would have thought the Thalys ought to have the same restriction (although I do realise that the Thalys runs at full speed on the new Dutch high-speed line [if this has now been fully commissioned: I am a bit behind with the railway news]).
2. There are a number of passenger trains / locomotives which do not allow you to include mail vans in the formation, or, when you do, the train is restricted to the mail car's speed, rather than the car assuming the speed of the rest of the train.
Eg. the 1990s double-decker EMU, all high-speed trains and the TRAXX locomotive (which accepts passenger-haulage, but without mail cars).
I'm guessing this is for realism, in that, these days, mail is transported using dedicated trains (or by lorry: pah!). But, in terms of OTTD, I find it only makes sense to have dedicated mail trains when cities get
really big.
But as I say, overall a fantastic set.
