So how do I use this thing? I've never used LTN, but I want to. It is so complicated I haven't figured out how to do the configuration although I understand the general concept. It seems this can make it easier to setup, but I don't know how to use it. I wired it to the lamp and setup a Requester, Provider and Depot stations, but the trains are not moving from the Depot. I get an error that there are no trains to service the request even though there are trains sitting at the depot. All the lamps are green.
