The Operating Searchlight Car No. 6822 was built on a RED No. 6511 flat car chassis with WHITE heat stamped lettering between 1961 & 1969.

The searchlight superstructure that was placed on top of this car was lettered "TRACK / MAINTENANCE" and also had simulated shovels, oxygen tanks and wire rolls. There is a BLUE attendant that most often is found with a painted face.

This car has AAR trucks that has either two operating disc couplers, or one operating, and one solid non-operational coupler.

There are three variations:

Variation A: GRAY superstructure with BLACK searchlight housing and AAR trucks with one disc and one solid coupler.

Variation B: BLACK lighting unit with a GRAY searchlight housing. This variation has AAR trucks with disc couplers.

Variation C: Is a scarce 1966 version that was heat-stamped "6828" in error.

MPC released this car in the Modern Era without the attendant.
