The Lionel Erie No. 610 Switcher used a BLACK body with YELLOW heat-stamped lettering and railroad herald. This engine had operating disc couplers at both ends, and some early production units would have a light. It was equipped with a three position directional unit whose control lever was adjustable from the bottom of the sheet metal chassis, and either one or two axle Magnetraction. Produced only in 1955, it is amazing that there are five variations:

Variation A: BLACK chassis, with light.

Variation B: YELLOW chassis.

Variation C: Identical to Variation A, but this version doesn’t have a light.

Variation D: Identical to Variation A, but this version has two axle Magnetraction and no light. Probably the first production.

Variation E: This variation has a service-station replaced body (Part No. 600-3) that has a nameplate on the sides similar to the Jersey Central No. 621.

Lionel issued this diesel for use on O27 gauge track, but it will operate equally well on the larger radius curves of O gauge track.
