Person…. – When you say vehicles are spacing themselves, are they just putting x amount of distance between them and the vehicle in front, or are they spacing themselves so that they arrive at each station along the line at regular intervals. I know the former of those 2 is correct for me and I even posted a thread with screenshot illustrating my point.
Azrael – that is an option but I like having tracks in both directions, especially on long routes. I might give it a try on my longest route when I next play though to see how it goes, I guess i could use it on a double track but just remove all signals except for at stations. Have to say thought that it seems a bit silly having to judge where to put passing points, or signals so that vehicles space themselves evenly. It would be different if the train could load at the station until its path was clear, then it would be worth doing
