The ALP-46 is an electric locomotive built in Germany by Bombardier between 2001 and 2002 for use in the United States. It is derived from the German Class 101. New Jersey Transit (NJT) is the only railroad to operate this model locomotive. They can be found all over the electrified NJT system, but are primarily used for service to and from Penn Station in New York City.

[edit] Orders

NJT ordered the first 24 ALP-46 locomotives in December 1999 and an additional five locomotives in September 2001. They were built by Bombardier (formerly ADtranz) at their Kassel, Germany plant. The first two locomotives were built as preseries locomotives for testing—4600 was tested on the TTCI test plant in Pueblo, Colorado, 4601 was sent to Kearny for testing on the NJT network. All locomotives were transported via road to the port of Bremen and shipped on Roro-ships of Wallenius Wilhelmsen Logistics to Port Elizabeth (NJ). The ALP-46 is compatible with NJ Transit's Comet IIM, III, IV, V, and Multilevel fleet. It was also used to pull Amfleet consists on Amtrak's Clocker service in its final days of operation.

In February 2008, NJT ordered 27 ALP-46A locomotives to ensure they have enough motive power for their multilevels when they are all delivered in 2010, an order for 45 more multilevels having been exercised at this time. These new engines have newer technology than their older sisters, being 6–10 years younger, that will allow for increased acceleration and operating efficiency. The ALP-46A's have a top speed of 125 mph (201 km/h). This contract included an option for an additional 33 locomotives, 9 of which were exercised on June 10, 2009 to begin replacement of the ALP-44.^[1]^[2] These engines are numbered 4629-4664. On November 13, 2009, Bombardier ceremonially handed over the first two completed ALP-46A's (4629–4630) over to New Jersey Transit over at Kassel plant in Germany. They arrived on NJT property on December 13. Locomotive 4629 was shipped by rail to a testing facility in Pueblo, Colorado, while 4630 was placed on the rails at the Meadows Maintenance Complex in Kearny for testing on property and maintenance training. As of April 5, 2011, all locomotives have been delivered.^[3]^[4]^[5]^[6]^[7]

On June 2, 2010, 4629 entered trial service on the Morris and Essex Lines, coupled to an ALP-46 in case of failure.^[8] As of May 7, 2011, all locomotives have entered regular revenue service.^[9]

Commuter rail operator GO Transit is considering the use of the ALP-46 for some or all of the operator's current lines. GO Transit has performed a study on electrification of their current diesel operations.^[10] Currently all GO rail lines use diesel locomotives with some that fall under US Tier 2 requirements.

[edit] ALP-46 Specifications

The ALP-46 locomotives produce 7,100 hp and are powered by overhead catenary. They can reach a top speed of 100 mph (161 km/h). Compared to its ancestor, the more powerful German Class 101 locomotive, the ALP-46 is about 10 short tons heavier since the carbody has been adapted to the crashworthiness standards of FRA. A polyol-ester cooled transformer reduces the catenary voltage and feeds two polyol-ester cooled traction converters in GTO technology. Each traction converter feeds the motors of one truck.

ALP-46A 4629 at Convent Station.

HEP transformer on ALP-46A 4637.

The ALP-46A locomotives are similar to the ALP-46 locomotives except that the traction converters are from a newer generation in IGBT technology. The converters are water cooled and have individual inverters for each motor. This generation sports the 7,500 horsepower (5,600 kW) output similar to the latest versions of TRAXX locomotives, as well as the ability to handle 14 multilevel cars without the assistance of a HEP helper locomotive. These locomotives are certified to run at 125 mph.
