I've been watching trains with a scanner/receiver in my hand/vehicle since about 1980, and the comments by the dispatcher are much more useful than just about anything else. I was watching last night and I normally search the whole VHF Railband and I heard the NS dispatcher tell someone who I couldn't hear, "There's a bunch of Eastbounds coming in the next hour or so, so if you need to do something, get it done, or you have to wait!". About 45 minutes later a bunch of Eastbounds started coming, along with a couple of Westbounds. Only real thing that stood out was a stack train passing me at MP 297was going about 40 and slowed down in a hurry with some banging and clanging. They were told to creep for a while until some train crossed ahead, but they never said what the other train was and where it was crossing.
Back when my dogs were alive, I would base my going out to the tracks in Holland, Oh by what the dispatcher said. If they said anything like, "It's about to get busy pretty soon!", I would make my dog(s) very happy and say the magic words, "Choo choos?", go out to the kitchen and pack some stuff to eat, ignoring their glares and spinning insanity, and load them up and go. Most of the train crews back in the Conrail days knew my dog Gus by name, but after the tracks went to NS, they knew him as the "Border Collie" (He wasn't, he just looked like one), or the "black and white guy". A few knew him by name, and it always made him happy when they yelled it as they passed. But if the dispatcher told a MOW crew it was going to be slow and they could take the track, I would make my dogs very unhappy and tell them we were staying home, resulting in a lot of dirty looks and sighing. Gus would be so put out he would pretend to ignore me. This was taken just as I was about to tell him we were staying home. I wish I had taken a pic of him with his head turned away and puffing his cheeks out sighing:
