Production:
The 621 Jersey witcher.

History
The 621 Jersey Central diesel switcher was produced for two years, 1956 and 1957. Lionel's version of the NW2 is an excellent representation of a real-life diesel switcher.

The plain blue exterior plus limited decals has made the 621 a less than exciting diesel, especially when compared to its cousin -- the 611 Jersey Central diesel switcher produced in 1957 and 1958. Although collectors and operators prefer the 611, the 621 -- along with its original box -- is actually harder to locate than the 611 diesel.

Features
Standard features of the 621 include: unpainted blue shell, orange decal and numbers, single axle Magnetraction, three-position E-unit (with the lever accessible from underneath the frame), dual operating couplers plus a gold ornamental bell and silver ornamental horn. The 621 did not include an operating headlight.

The frame was always black with a center skirt. End railings, as well as sheet metal steps, appeared at each end of the frame.

Additional Detail, Photos & Box Information
The blue shell can be located in various shades of blue -- none of which can be considered rare. Additionally, the center window support is fragile and is frequently found either cracked or completely missing.

Only Known Variation - All 621's were produced with an unpainted blue mold and orange decals and numbers.
