Rotary Snow Plows
After steam locomotive construction ended, Lima-Hamilton built four steam operated rotary snow plows. The three cylinder Pacific Coast Shay engine design was used, this time two banks of 3-13x15 engine assemblies were installed. The boiler shop was activated for the last locomotive boilers and construction was carried out in the locomotive erecting shop. A number of men who had built the Shays were brought back to handle machining and setting the valves. The fling was short-lived, The first going out of the plant in December 1949 and the last in February 1950. The Union Pacific took the first and third units while the Soo Line took the second unit and the last went to the Rock Island. It was the last application of Shay technology in the railroad industry.
