It would seem the pull-by's would have worked, had you been able to just run the power around, and get on the hind end. We used to build the train backwards, for what was needed going into Bingo. The size of the siding for the pull-by didn't allow for a single move. Somewhere along the way, the "powers that be" decided that if the train was going that way, anyways, why not add freight, to the hind end? Another bit of switching, when pulling-by. I thought we had the "Super Unleadeds" to run the freight, but what did I know? (I was the night TM, for a while until I got tired of watching everyone else run....) One night, the train went into emergency, coming around the "new connection". The cndr walked back, at 2 in the morning, and found the marker missing from the last car. He walked a ways back, then gave up, and the train ran sans marker. Imagine the suprise, of the next train coming by the connection, when they saw 10 LPG tank cars, still coupled together, laying at the bottom of the hill, along the outside of the curve. The marker hadn't fallen off, but the last 10 cars in the train did!!! I had the unpleasant task, of running those cars back to WS, with a pair of SD's, one engineer on each end, and no air, or brakes, on the train. No dynamics, and an engineer who thought I was yelling "faster" on the radio, made for a harrowing trip, down the mountain, at speeds exceeding 60 mph. At one point, we slowed to below 40, and I saw a wrecked ATV sitting beside the track. MTV had plugged the air, upon seeing the ATV on the tracks, but never told me. He recovered the air, for his engine, without stopping, and we kept on rolling, all the way back to WS. The FRA woulda had our asses, on that one.......
