does anyone have a video tutorial on how to lay signals down in Trainz Sim 12 ? Sorry dont mean to flood everyone with questions but really dont understand the signaling process as far as where to put them and which ones to use. There's only about 10,000 signals in the menu to choose from...lol. anyway, i tried laying down some., and sometimes it would give me a green light then other were red or flashing yellow. Just cant figure out where im going wrong. Thanks again
