I currently have a world, where after a Train Station, the Railroad track only goes downwards and after that almost immediately reaches the next train station. The problem that I saw with that was the trains being way too fast to be able to break in time for the train to stop, resulting in a funny immediate stop as if it hit a wall at the station. My suggestion to solve issues like that would be to be able to add speed limitations which will make the train brake at such passages. The Idea would be to be able to set up a sign at the railroad and drag the end point to any point behind it but only to the next switch, so problems like trains on the other railroad suddenly abiding to the speed limit would be avoided. Also it looks rather stupid when a train goes to a full stop from over 100 km/h so if the train isn't able to stop at the station, it should just shoot over it and then disply an error message like when it can't navigate to the train station.
