NRE has just completed and delivered two APU Locomotive Control Units to Ontario Northland. These units were remanufactured from converted Amtrak F40PH Locomotives 317 and 394.
The APU Locomotive Control Unit is a complete self-contained mobile electric generating plant capable of supplying all electrical power required for the heating, lighting, air conditioning, and other hotel power needs of up to 12 connected passenger cars.
The units contain twin alternator sets, each capable of operating independently or in parallel. The set nearest the “front” end of the cab car is the master set, and adjacent to it are the control devices for functions common to both power plants.
