The ALP-45DP is a dual-mode locomotive currently being built by Bombardier Transportation. It was unveiled to the public on September 21, 2010 at Innotrans 2010.[1]

[edit] New Jersey Transit

New Jersey Transit has ordered 26 of these locomotives[2][3] to bridge gaps between non-electrified lines (the Raritan Valley Line and the southern section of the North Jersey Coast Line) and electrified sections of track into New York Penn Station,[2][4] which has an ordinance prohibiting locomotives from emitting diesel smoke within its tunnels.

They are to be numbered 4500-4525 with possible options numbered 4526-4588. The purchase of an option for ten additional locomotives was approved on July 14, 2010, as part of NJ Transit's 2011 capital budget.[5][6]

Unit 4501 arrived in the United States on March 13, 2011 at Port Newark, N.J., from where it was sent to the Transportation Technology Center in Pueblo, Colorado (over CSX by way of Selkirk Yard) for testing. 4500 arrived in late April 2011, and was officially unveiled on May 11, 2011 at Newark Penn Station.[7] This unit will test on NJT property pending FRA approval, prior to an anticipated start of commercial usage in spring of 2012.[1]

As of January 13th, 2012, locomotives 4500-4507 have arrived on property. [8]

[edit] Agence métropolitaine de transport

Montreal's Agence métropolitaine de transport (AMT) has also ordered a batch of 20 locomotives (with an option for 10 more) for the Repentigny-Mascouche Line (AMT).[2]. This new line is mostly un-electrified, but joins the existing electrified Deux-Montagnes Line to access the Central Station through the poorly ventilated, 25 kV AC electric only Mount Royal Tunnel.[2] They are to be numbered 1350-1369.

AMT 1350 arrived in Montreal on June 9, 2011, after being shipped to Newark and then moving north to its new home.[9] An ALP-45DP has been recently spotted working on the Mont-Saint Hilaire line in diesel mode.

As of January 2012, locomotives 1350-1360 have arrived on property.[10]

[edit] Specifications

The ALP-45DP electro-diesel locomotive is derived from Bombardier's ALP-46 electric locomotive that has been used by New Jersey Transit since 2002,[2] although it started production after the uprated ALP-46A. Its two Caterpillar 3512C-HD engines are arranged symmetrically around the transformer and traction converters to keep the weight balanced. As a result of the additional engine-generators, the ALP-45DP is approximately 2 m (6 ft 7 in) longer and 40 t (88,000 lb) heavier than the ALP-46 and ALP-46A.[1]

Under the wires, the ALP-45DP has approximately 70% of the power of the ALP-46A (75% of the power of the ALP-46), although both its tractive effort and dynamic braking effort are similar. Away from the wires, it has much less power than in electric mode (55% to 72.5%), but has similar power and tractive effort characteristics to NJT's existing PL42AC diesel locomotives.
