I’m sorry, chakotay68, but if you imply that the signaling in TF is good I have to disagree with you. You are very limited by the signals. You can use only path signals, no presignaling. In my opinion the best signaling was in OTTD, followed by Locomotion. The only advantage in TF is that you can have two trains in the same block if their paths don’t intersect. But that’s about it.
