TENSHODO SPUDS

(Self Propelled Universal Drive)


Units are available in a variety of wheelbases and plain or spoked wheel sizes. A small square, open frame motor is geared to the axles and pickup tabs on all wheels provide a self contained unit. Lugs are mounted on top for wiring lights and dummy truck pickup.

With some weight added over truck, one or two trailers may be pulled. Speed will vary with wheel size, but is typically less than 80 smiles/hr @ 12v. MUing several units works very well. Although units are available for road diesels, even a pair does not have enough power handling reasonable trains. However these may handle lighter industrial switchers .

Stock number WB-31 = 31mm / 3.5 = 8.857' = 8'- 10.286" not 9' as listed. 287 = 28.7 / 3.5 = 8.2' = 8'-2.4".
On the GT-126 = 26.2mm = 7.486' = 7'- 5.83".

Measure side frame wheelbase and pick the closest. A few scale inches are hardly noticeable, since pedestals cover most of the wheel..


Note: Adjust brightness and contrast for optimum viewing.
