Bombardier ALP-46

The ALP-46 is an electric locomotive built by Bombardier Transportation for NJ Transit. This comprises of two variations: the ALP-46 and ALP-46A. Both classes can be found all over the electrified NJT system, but are primarily used for service to and from Penn Station in New York City. The ALP-46 is derived from the German Class 101. They will be used to replace the Alp 44s which were retired in 2012.

==History and Other uses==
NJT ordered 29 locomotives: the first 24 ALP-46 locomotives in Decemeber 1999 and an additional 5 locomotives in september 2001. They were built by Bombardier (formerly ADtranz) at their Kassel, Germany plant. The first locomotive, 4600 was completed and tested starting on the TTCI test plant in Pueblo, Colorado, locomotive 4601 was later tested on NJT Northeast corridor. Later line tests were completed with success and soon it made its inaugural first run on the Morris and Essex line on a train from Dover to Hoboken. All 29 Alp 46s ,which at point Njt retired the Alp44s at the end of 2012. 
On February 2008 NJT ordered 27 (125 mph) 201 km/h ALP-46A locomotives from Bombardier, which were to haul Bombardier MultiLevel Coaches. The estimated value of the order was €155 million (approximately $230 million). In June 2009, NJT took up an option for a further 9 locomotives,and accepted it at a cost of $72 million.
==Description==
===ALP-46===
The ALP-46 locomotives produce 7,108 hp (5,300 kW) and are powered by overhead catenary. They can reach a top speed of 100 mph (161 km/h). The ALP-46 is derived from the DBAG Class 101 locomotive; its top operating speed is 125 mph (201 km/h). The locomotives use Bombardier's MITRAC 3000 electric propulsion system. The system consists of a polyol-ester cooled transformer to reduce the catenary voltage which feeds two polyol-ester cooled GTO based traction converters (Bombardier MITRAC TC 3100 series). Each traction converter feeds the motors (Bombardier MITRAC DR 3000 series) of one truck.
===ALP-46A===
The ALP-46A locomotives use Bombardier's MITRAC 3000 electric propulsion system. The traction converters (Bombardier MITRAC TC 3360 series) are from a newer generation based on IGBT technology. The converters are water cooled and have individual inverters for each traction motor (Bombardier MITRAC DR 3000 series). Power at rail is increased to 7,500 hp (5,600 kW) and top speed is increased to 125 mph (201 km/h), although NJ Transit limits them to 100 mph (161 km/h) For safety reasons.The bell used is also changed to Graham White E-Bells, as opposed to steel bells.
