The Progress Rail PR43C is a 4,300 hp (3,210 kW) C-C genset diesel-electric locomotive built by Progress Rail Services Corporation. It is the result of a conversion of existing EMD SD50 locomotives. This involves replacing the original EMD 645 prime mover with a pair of Caterpillar engines, a 3,600 hp (2,680 kW) C175 engine and a 700 hp (522 kW) C18 engine.[1][2] The locomotive was jointly designed by Progress Rail and Norfolk Southern Railway. Development began in 2008.[3]
Three locomotives have been built: two are operating in revenue freight service on Norfolk Southern, while a third is operating as a demonstrator unit for Progress Rail.[2] Norfolk Southern has four more PR43Cs on order.[3] The locomotives operating for Norfolk Southern work on freight trains in central Illinois, leading to speculation that they are being tested, as Caterpillar's headquarters are located in Peoria, Illinois.[1]
All three locomotives were manufactured at Progress Rail's Mayfield, Kentucky factory.[1]
The process of converting an SD50 to a PR43C alters the external appearance of the locomotive; the original radiator section is replaced with a larger one that is similar in appearance to that of an EMD SD70ACe or SD70M-2.[1]
