GP40PH-2, GP40PH-2A, GP40PH-2B
In 1991-92, NJ Transit sent its ex-CNJ GP40PH units out for rebuilding. The units were rebuilt as GP40PH-2 locomotives and, with the exception of 4101, renumbered out of order. At this time, the units were restricted on the Newark Division and primarily kept to the Hoboken Division. By 1999, the units were often used on the Pascack Valley Line service, as they were the only units equipped with the Speed Enforcement System equipment needed on the line. They are now found mainly on the Hoboken Division.
New Jersey Transit would later order two more sets of GP40PH-2 units; these units were rebuilt from former freight GP40 units, not from GP40P units as the first order has been. The first order (GP40PH-2A) in 1993 consisted of six units, numbered 4145-4150, and were rebuilt by Morrison-Knudsen. These units, with the exception of 4148, which was rebuilt as a GP40PH-2B and renumbered after a collision, are classified as GP40PH-2A, though the units lack the "A" designation on their stenciling. The second order in 1993-94 was rebuilt by Conrail, and was for 19 former Penn Central units, numbered 4200-4218. These units are classified as GP40PH-2B. A twentieth unit, the GP40PH-2A numbered 4148 wrecked in 1996, was also rebuilt into this class and renumbered 4219 in 1997.
Metro-North ordered a single GP40PH-2 unit; numbered 4190, it is officially classified as a GP40PH-2M. 4190 was rebuilt by Conrail in 1992. The current number of this unit is 4906
A GP40PH-2 is being used on Amtrak's Piedmont train. It is owned by the North Carolina Department of Transportation rather than Amtrak itself.
