The Bombardier ALP-46 is an electric locomotive built in Germany by Bombardier between 2001 and 2002 (and 2009–2011 for the ALP-46A) 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 locomotive model, which is used across the electrified NJT system, specifically on the Northeast Corridor, North Jersey Coast, Morris & Essex, and Montclair-Boonton lines. These locomotives replaced the ALP-44 locomotives, which were all retired by 2012.

NJT ordered 29 locomotives: the first 24 ALP-46 locomotives in December 1999^{[citation needed]} and an additional five locomotives in September 2001.^{[citation needed]}

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 Newark-Elizabeth Marine Terminal, New Jersey.

In February 2008, NJT ordered twenty-seven 125 mph (201 km/h) top speed ALP-46A locomotives from Bombardier, which were to haul Bombardier MultiLevel Coaches. The estimated value of the order was €155 million (approximately $230 million).^[2] In June 2009, NJT took up an option for a further nine locomotives, and spare parts, at a cost of $72 million.^[3]

On November 12, 2009, Bombardier ceremonially handed over the first two completed ALP-46As to New Jersey Transit over at their Kassel plant in Germany.^[9]

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.^{[citation needed]}

All locomotives were delivered by April 5, 2011, and by of May 7, 2011, all locomotives have entered regular revenue service.^{[citation needed]}

In October 2019, as part of New Jersey Transit's 40th Anniversary, locomotive No. 4636 was wrapped into a Pennsylvania Railroad scheme.^[10] In September 2023, locomotive 4640 was wrapped in a heritage disco stripe scheme, in preparation for the 40th Anniversary of NJ Transit Rail Operations.

Both the ALP-46 and ALP-46A have been used to haul NJ Transit's Comet IIM, IV, V, and Multilevel fleet.^[11] The ALP-46 was also used to pull Amfleet consists on Amtrak's Clocker service in its final days of operation.^[12]
