Heading home from running errands, Mitchel and I caught the one of the RPRC's SW1200's and caboose easing into the three track yard off Wright Ave to pick up some tank cars. The caboose is used for long backup moves during switching to protect the crew on the end of the train. It's always a pleasure to see the caboose. It seems so unexpected these days. Most of the time though, they keep it close to the engine except when doing the backup move.
