Das Boot was a 1980's movie about German U-boats and U-boats were the nickname of GE's U-series of engines that started in the 1960's. They were followed up by the C and B series which were subsequently nicknamed C and B boats (their body style was similar.) The Finger Lakes Railway has at least one U-boat and a number of B-boats. They are one of the last operators of these beasts and I spent most of the day shooting them!
