From 1925 to 1928, GE and Ingersoll-Rand built engines, Alco assembled bodies, and GE furnished the electrical equipment for a series of small industrial locomotives. GE began building small, diesel electric, 20-25 ton locomotives in 1938. Between 1938 and 1974, 550 locomotives in the 20-50 ton size range were built. In 1956, GE sold the under-25T business to Rogers Brothers of Albion PA; but continued to offer 25 ton and larger industrial locomotives developed specifically for tight radii to move heavy local loads. The prototype of the SEARAILS PowerMAX! GE25T is found in Petaluma, California across Washington boulevard from the Southern Pacific Railroad Station.
GE25T N SCALE (1:160) DIESEL SWITCHER AVAILABLE IN BOTH 6.5MM (NARROW GAUGE) AND 9MM (STANDARD GAUGE)
CONTINUOUS PRODUCTION QA/QC TESTING TO ASSURE MARKET ACCEPTABLE PERFORMANCE.
The assembled loco weighs 22.2 grams (.78 ounces.) The 15'6" LOA prototype is 1.1625" in Nn3 scale. Wheelbase 11mm, 6.5mm gauge. Runs smoothly on Micro Trains and Rokuhan sectional test track, with a radius of 197mm (7.75"). It is tested with PRMLOCO throttle with a maximum 10V output.
The loco runs smoothly with some noise which sounds like a diesel sound unit! The loco pulled eight standard Micro Trains box cars, Gondola, and Caboose at the 2011 NMRA/NTS with little effort and no wheel slip. It experienced severe wheel slip in reverse or pushing twelve cars.
It pulls ten cars more easily, but is most comfortable pulling or pushing eight cars - still quite a bit more than the prototype would probably have handled, and quite impressive for Nn3 or N.
