C&O DM-1, Dynamometer Car - Chesapeake & Ohio RR  Contributor's Pick!       
The dynamometer produced an "EKG"-style paper printout of engine performance, except the paper was nearly 4 feet wide as you can see on the table below! A video by Harry Eck, former superintendent of Locomotive Operations (who just passed away July 12, 2012), explains in detail how the car worked. Well worth watching!!!!
