I'm pretty new to this game and I've only played a few UK and DE routes and timetables so far, but I find that they're pretty boring if every signal I go by is green. I have no idea if that's true to life, but I was wondering if it's possible to add other trains to the lines in some way so that I get a different signal aspect every once in a while to add some excitement and the need for vigilance.
Related question, are there groups that do realistic multiplayer games with the possibility to actually contact the signaler and coordinate routes?
