Process Locomotives are “green” by design and employ twenty-first century technology along with features comparable to those found on new multi-million dollar locomotives at a fraction of the price. They are industry-proven from Alaska to Mexico and Eastern Virginia with all units sold to date still in continuous service, some for as long as 11+ years.

 Features include patented high-adhesion traction control, EPA emission-certified engines, radio remote control, remote maintenance monitoring, video and data event recorders, etc. They are rugged, highly dependable, and automated for safety, fuel efficiency, and simplicity of operation.

 Process Locomotives are built from the rail up using a frame, trucks, and traction motors obtained from cores. These are carefully inspected and reconditioned to OEM standards. Other systems and components are new, and incorporate the most advanced technology available to provide reliability, efficiency, safety, and economy.

 Process Locomotives are available in Yard-Switcher or Road-Switcher models, with 4 or 6 axles, from 400 to 3000 Horsepower.

Models Available:

·          PL Series Diesel Electric

·          PL-ZSE Dual Mode Operation

·          PL-ME Multi-engine
