I was out of Santa Fe territory by that time. I covered areas from El Paso and Silver City to Raton, Gallup to Albuquerque, and Belen to Clovis.
Too bad. They were very effective.
No blinking on any CSX, NS, Conrail, Amtrak locomotives or NJ Transit MU units that I have seen. Perhaps in the denser populated areas of the East, the blinking feature, if available, is not used. Most grade crossings are guarded, but I have seen plenty of drivers go around the gates, fortunately with no catastrophic result. To those drivers, it would not matter what kind of lights were in use on the train. They just like to gamble with a 79 mph locomotive.
I also did not see any blinking ditch lights on Amtrak’s Vermonter. There were plenty of unguarded grade crossings in rural Vermont – at least one per mile on average. Motorists are warned primarily by the blare of the locomotive’s horn.
