The only case where I can see that happening is when the train in front is slower that the train behind it.Mchl wrote:The distance will be longer, yes.
But it often happens in my games, that when the signals are too close to each other (and so do trains) then on heavily used tracks,trains have problems reaching their maximum speed, because they constantly run into train ahead of them. Not once I was able to solve that by removing some signals.
A question of balance as usual
Signals every two tiles works flawlessly for me.
