A shot of the bunks in the back end of Pennsylvania Railroad caboose (# 477947), built in 1942 at the Altoona shops, on display at the Railroad Museum of Pennsylvania in Strasburg, PA.
The role of the caboose on trains was to provide a shelter at the rear of the train where the crew could sleep and eat and get out of the elements. At stops the crew would exit and inspect the cars for hazards like overheated axle bearings, broken or dragging equipment and loose couplings. In each caboose was a desk, like the one you see here where the crew could eat and the conductor could do his paperwork and record keeping for each run of the train. For public safety reasons, cabooses were mandatory on all U.S.. freight trains up until the 1980s when they were phased out and their functions replaced by improved technology and monitoring systems.
