[edit] Service
[edit] New Jersey Transit
The ALP-44 was originally ordered for New Jersey Transit's electric lines, with fifteen units, designated ALP-44O's(numbered 4400 through 4414), delivered in 1990. A second order for five more units, designated ALP-44E's (numbered 4415 through 4419), was delivered in 1995, and the final order was for 12 ALP-44M units (numbered 4420 through 4431) and was delivered in 1996.
As of December 18, 2010, locomotives 4400-4404, 4408, 4410-4420, 4422-4423, 4426-4427, and 4419-4431 have been retired. Units 4405-4407, 4409, 4421, 4424-4425, and 4428 are still in service. All units have been retired with the delivery of the remaining ALP-46A locomotives, except 4405 and 4409, which are assigned to ACES. As of June 15, 2011, units 4402,4403,4408,and 4410 have been leased by Amtrak for work train service through the Hudson river tunnels.
[edit] SEPTA
SEPTA received a single ALP-44M unit, #2308, from ABB, which was part of a damage settlement for a lawsuit stemming from the late delivery of N5 cars for the Norristown High Speed Line. ABB gave SEPTA an ALP-44M, instead of the EMD AEM-7, which make up the rest of SEPTA's electric locomotives, because EMD had discontinued the production of the AEM-7.[citation needed]
[edit] Specifications
The ALP-44 based on the Rc6 model and designed specifically for New Jersey Transit as a variant of the EMD AEM-7 electric locomotive in use by Amtrak, MARC, and SEPTA. The ALP-44 is powered by overhead lines through one of the locomotive's two pantographs and can produce up to 7000 hp (5.2 MW) with a top speeds of up to 125 mph (201 km/h). In commercial use however, both New Jersey Transit and SEPTA ALP-44s are cleared for speeds up to 100 mph (161 km/h).
[edit] ALP-44M
The ALP-44M is a variant of the original ALP-44 design. It includes a microprocessor control for functions such as braking and the EPIC brake controller.
[edit] Overhaul
NJT's ALP-44's were to be overhauled for a cost of $2 million during a two year period by Philadelphia-based Interfleet Technology. A car builder had not yet been selected to carry out the overhaul.[1] However, as of June 2009, NJT has decided that it would be more efficient (economically and physically) to replace the ALP-44's rather than overhaul them, and has exercised an option of 9 additional ALP-46A's to enable the replacement to take place.[2]
