You are right saying that one can pack more trains tightly together on a track with signals every centimeter, but if you are that desperate in adding trains on a track, maybe it’s more valuable to invest in parallel tracks and get those trains running again in stead of having them packed one after the other?
Just a reflection. So, literally, you are right. I have to rephrase and argument my statement a little clearer, I think. 😉
thank you for your feedback.
