As much out in uncharted territory that I am, there are several gated RR crossings. I'm about 1/3 mile from the tracks, so pretty much, to go anyplace toward civilization, I need to cross one of those crossings. No big deal, usually. Car/truck traffic is mostly really light except for that 6am and 5pm slot when folks are trying to get to and from work spots. So here's the thing. I have begun to notice really strange timing of the gates. All the crossings have big gates on the oncoming side, and little gates on the opposite side of the tracks. When a train approaches, usually at about 65mph, we get 20 seconds of "bell, flashing lights, then gates down" before the train is at the crossing. The large gates go down first, immediately followed by the small gates. But, when the train passes, it takes a full 40 seconds after the train has left the crossing area, before the small gates go up, and then another 15 seconds until the big gates go up. Yes I've timed 'em. So last nite, I happened to need to go to the bank to arrange cash and checks and such, and a train came by just as I was walking over (different) tracks. Same 20 seconds of "warning" before the train was at the crossing. This crossing had "big gate" only, on the approaching side, and nada on the opposite side. When the train passed, it was 5 seconds before the big gate lifted. I was thinkin'... well that's more like it! Anybody RR savvy and can 'splain this all to me?
