[edit] Service

The ALP-44 was originally ordered for the New Jersey Transit, with fifteen units (numbered 4400 through 4414) delivered in 1990. A second order for five more units (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.^{[citation needed]} SEPTA received a single ALP-44M unit (numbered 2308) from Asea Brown Boveri (ABB), which was part of a damage settlement for a lawsuit stemming from the late delivery of N5 cars for SEPTA's Norristown High Speed Line. ABB gave SEPTA an ALP-44M, instead of the AEM-7, which make up the rest of SEPTA's electric locomotives, because the manufacturer 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 7000hp (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 are to be overhauled for a cost of $2 million during a two year period by Philadelphia-based Interfleet Technology. A car builder is yet to be 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 excercised an option of 9 additional ALP-46A's to enable the replacement to take place. ^[2]
