How about I just ask the questions? Is there a train to train channel? When a train is stopped and waiting for another train to pass on the next track what is this called? Why do I see trains stopped before the crossing and the crossing arms are down and functioning and a train will just appear to be waiting for 3-5 mins before it proceeds? Do engineers or conductors ever use FRS or GMRS or MURS or HAM to communicate with eachother without the company knowing? Is there 1 or 2 specific channels that are always in use?
