So, I'm trying to use the tram to go to different floors in my building and need it to stop at certain places not just the bottom and the top. I already have. I'm trying to place "Rail Tram Stop" 's on my rail and it won't let me. I'm certain you van do this as I just watched a video on how to work the trams, but for some reason I can't do that. Can someone please help me ASAP?
