GP40FH-2
In 1987, New Jersey Transit and Metro-North ordered a set of GP40 locomotives called GP40FH-2s which were completed by Morrison Knudsen between 1987 and 1990 and combine the standard cab and frame of a GP40 with the cowl from an ex-Burlington Northern F45. A total of 21 units of this type were built; 15, numbered 4130 through 4144, were delivered to New Jersey Transit, and the remaining six, numbered 4184 through 4189, were for Metro-North.
New Jersey Transit's units are slated to be retired eventually, replaced by new PL42AC locomotives from Alstom. GP40FH-2s 4130-4134 were sent to MotivePower Industries to be rebuilt into switcher units. Metro-North has begun sending their units out for significant maintenance and upgrades. Metro-North sent units 4184-4189 to MPI in 2007, when they were rebuilt as GP40FH-2Ms 4900-4905.
