ABB ALP-44

The ABB ALP-44 is a class of electric passenger locomotives that Asea Brown Boveri built between 1989 and 1997 for New Jersey Transit and, with a single unit, for SEPTA in Philadelphia. NJ Transit bought 32 of them in three batches, the original ALP-44O, the extended ALP-44E and the microprocessor-controlled ALP-44M. The design was based on the Swedish Rc6 and was a variant of the EMD AEM-7 used by Amtrak, and the name stands for ASEA Locomotive Passenger 4-Axle 4.32 MW. It is fed from overhead lines through pantographs, can produce up to 7000 horsepower and has a design top speed of 125 miles per hour, though commercial service was cleared only to 100. All NJ Transit units had been retired by 2012 and most have since been scrapped, with one donated to a railroad historical society.
