I remember when one could see a caboose at the end of a train. The end of the caboose came in the 1980s when technology and reduced federal regulations on train crews made the caboose redundant. This B&O caboose stands on a spur near US 231 as it leaves the north end of Greencastle, Indiana.
The caboose marked the end of the train and housed a crew that monitored the train’s condition from that position. The bay windows and tower aided crew members in seeing the train. The conductor’s office might be in the caboose which also might house a small kitchen.
