The Lionel Erie NW-2 Switcher No. 610 used a BLACK body with YELLOW heat-stamped lettering and railroad herald. There is no skirt on the sheet metal frame. Most copies are found with one-axle Magnetraction.
This engine has 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. Produced only in 1955, it is amazing that there are five variations:
Variation A: BLACK painted chassis, with light.
Variation B: YELLOW painted chassis. No light.
Variation C: Chemically blackened sheet metal chassis. This is the most common version.
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.
