The Lionel Seaboard NW-2 Switcher No. 6250 was produced for two years in 1954 and 1955. Created on a painted BLUE and ORANGE body with WHITE "SEABOARD" lettering on the sides and the road herald decal on the cab, it was equipped with a three position directional unit whose control lever was adjustable from the bottom of the die-cast metal chassis, vertical worm drive motor that powered two axles with magnetraction, interior lighting at both ends, and electronic couplers. This engine was an excellent runner. There are three variations:
Variation A: The "SEABOARD" closely spaced lettering on the side is a decal. It is difficult to find this version today with the decal intact (1954).
Variation B: The "SEABOARD" lettering is smaller and is rubber-stamped on the sides. The spacing of the letters on this stamp did not take into account the details cast into the body. As a result the stamp was damaged during the manufacture of these shells. This is the first production of this diesel using a rubber stamp (late 1954 - early 1955).
Variation C: Rubber-stamped "SEABOARD" with widely spaced letters to account for the side panels cast into the sides of the diesel (1955).
Lionel issued this diesel for use on O27 Gauge track, but it will also operate on the larger radius curves of O Gauge track.
