Roundhouse 2771 Factory Painted Brown Climax Locomotive Kit w/Universal Drive Fix

Excerpt from MRRHQ Collectible Roundhouse 2771 Factory Painted Brown Climax Locomotive Kit documents:

"The Climax Locomotive was produced by the Climax Manufacturing Co. in Corry, Pennsylvania. Designed in the late 1800's, the Climax was designed as a logging locomotive with a 1:1 gear ratio and attained a maximum speed of 12 mph. Also of interest is the fact that the Climax locomotive was also used for passenger service utilizing a 2:1 gear ratio, giving it a whopping 20 mph top speed! The early styled Climax design was a virtue of simplicity: one flat car with a 2-cylinder tug boat steam engine in the center, enclosed by a cab: a boiler at one end with a fuel bunker at the other end! The Climax was powered by a transmission and spline shafts, coupled with universals located below the superstructure and centered between the geared trucks..... much like today's automobile."

The Climax, along with their other iconic Box Diesel and 2-Truck Shay locomotive kits, have become synonymous with the Roundhouse name over the years. Though admittedly noisy, finicky and often problematic, they are a must have for all model locomotive aficionados.
