Lackawanna484, Yeah, that is so true about speeding. On my one and only ride in the cab of the Southern's Crescent in 1977 we noticed a cop car with full lights and sirens on some of the roads that were near the track. We were northbound out of Salisbury, NC with High Point being the next stop. We didn't think anything much about it. At High Point a cop climbed up into the cab and asked which one of us was the engineer. The guy at the controls said he was. The cop asked for his license and registration. We laughed. He didn't. He gave the engineer a ticket for speeding more than ten miles an hour over the speed limit of some town (either Sepncer or Linwood -- I don't remember). The guy delayed the train leaving, because no one could produce a registration and insurance document for the locomotive. He finally wrote down some things off the safety inspection form that was behind glass on the wall in the cab. He had a radar capture the train and ours was the one he targeted.
After we left we commented on the guy acting more like Barney Fife (sp?) in Maybury RFD (which was fictionalized not too far away northwest of Greensboro).
I never found out if the engineer was fined or what. But, speeding within the town limits of that town was interpreted as applying to trains, too.
