The MPI MP33C is a model of diesel-electric freight locomotives designed and built by MotivePower in Boise, Idaho, USA. To date[when?] all orders have been for Australian operators.

In April 2011, five were ordered by CBH Group, in Western Australia.[1][2] In May 2012, ten were ordered by Railfirst Asset Management[3][4] followed by a further six in June 2013.[5][6] The latter six were delivered in February 2015.[7]

Specifications

The MP33Cs are hood unit locomotives with a single cab at one end, and ride on three axle bogies of C-C (Co-Co) wheel arrangement (33 signifying 3,300 hp and C, three driven axles per bogie).[2]

The locomotives are equipped with a Cummins V18 QSK78 prime mover rated at 3,300 hp (2,460 kW).[2]

The engine blocks for the prime movers are cast in Germany and sent to the Cummins engine plant in Daventry, England, for the final machining and assembly process. They are then fitted to the locomotive in Boise, Idaho.[8] All are fitted with 1,435 mm (4 ft 8+1⁄2 in) (standard gauge. CF locomotives are fitted with D87 traction motors.[2] CBH Locomotives are fitted with D77/78.
