caption_attribution_description: Diagram of Chicago and North Western Railroads's GE-Ingersoll Rand diesel-electric locomotive with road number 1200 delivered in August 1930. The locomotive pictured was the last built 600 hp unit and was 1957 scraped.
context_page_description: The GE boxcabs, sometimes also GE IR boxcabs, were diesel-electric switcher locomotives succeeding the ALCO boxcabs. The locomotives were built by General Electric and Ingersoll Rand without ALCO. Production lasted from 1928 till 1930. These boxcabs were often termed oil-electrics to avoid the use of the German name Diesel, unpopular after World War I.
context_section_description: All models have chassis and running gear, generator, traction motors and controls from GE, and Ingersoll Rand provided the diesel engine. The principle of operation was the same as modern locomotives, the diesel engine driving a main generator of 600 volts DC with four axle-hung traction motors. In contrast to the ALCO boxcabs having a design with side doors and ladders the GE boxcabs have front doors and end platforms with steps. The underframe was cast iron. The radiator system was sitting on the roof of the locomotive. At each locomotive end a GE Model CD65 motor with a Sturtevant multivane fan was pressing air through the radiators.
  Two models were in series production and two versions were only produced once: 
  a 60-Ton locomotive with a six-cylinder four-stroke in-line engine of 300 hp
  a 100-Ton locomotive with two of the same engines as the 60-Ton model
  a 120-Ton locomotive with a single six-cylinder 800 hp unit (1 prototype built for Erie Railroad)
  a 120-Ton locomotive with two of the same engines as the 60-Ton model (1 unit built for CN)
