Prototype Info:
Based on prototypes that were built during the 1960s, these cabooses were popular on railroads from coast-coast.

With the advancement of the End-of-Train device, cabooses slowly began to fall out of favor. However, in the early 2000's, "shoving platforms" began to appear as a place to safely house a crew when a reverse move was required. Instead of riding on the side of a freight car, the crew member now has a safe place to stand, while guiding the rear of a reverse move.
