ABB ALP-44
The ABB ALP-44 is an electric locomotive which was built by Asea Brown Boveri (Sweden) between 1989 and 1997 for the New Jersey Transit and SEPTA railway lines. As of 2014, only SEPTA still operates the ALP-44 in revenue service, as New Jersey Transit has retired its fleet.

New Jersey Transit
The ALP-44 was originally ordered for New Jersey Transit's electric lines, with fifteen units, designated ALP-44O ("O" denotes Original) and numbered 4400 through 4414, delivered in 1990, with prototypes 4400 and 4401 in late 1989. An option order for five more units, designated ALP-44E ("E" denotes Extended) and numbered 4415 through 4419, were delivered in 1995. The final order for 12 ALP-44M units ("M" denotes Microprocessor) numbered 4420 through 4431 were delivered in 1996 and into early 1997 for the new Midtown Direct service.
As of late 2011, all NJ Transit ALP-44 O, E, and M locomotives have been retired. All units were retired with the delivery of the remaining ALP-46A locomotives, except 4405, 4407, and 4409, which were assigned to ACES; however, these remaining units were also placed into retirement with the cancellation of ACES service in early 2012. Units 4402, 4403, 4408, and 4410 were leased by Amtrak for work train service through the Hudson River tunnels for a period of time during summer 2011, but have since been returned.
