The Operating Horse Car No. 3356 would unload horses into the corral and the vibrator located in the corral would load them back again into the car. Lionel liked "things" that "vibrated," and they used this mechanism on many of their accessories and operating cars.

Produced in 1956 until 1960, this car came with bar-end trucks and tabbed couplers (Variation A). Again manufactured from 1964 to 1966, and this version has aar trucks with disc couplers (Variation B).

The easiest way to tell these variations apart is that the B Variation has no built date, while Variation A has "BLT 5-56" imprinted on the sides. The B Variation is slightly harder to find today.

The car came with nine horses that were operated with the use of a 6019 or UCS track section that was located in front of the platform.
