New Jersey Transit no. 4408 leading a long distance passenger train into Summit station NJ. 4408 is an electric locomotive of the type ALP-44. As those who are familiar with European trains can probably recognise, it is a close relative of the Austrian classes 1043 and 1044, and is based on a Swedish design by Asea. Asea Brown Boweri ABB built these in 1989-97 and NJT bought 32 of them. This one was delivered in 1990. In 2012 New Jersey Transit took all of its ALP-44 machines out of use and stored them for potential further use.

New Jersey Transit locomotive 4521 is of the new generation of locomotives which has superceded the ALP-44s shown above. This model was designed by what then was ADtranz, then Bombardier of Canada, even later Alstom. It is of the type Bombardier ALP-45 DP. It is a locomotive with just one single driver's cab and it is an electro-diesel dual mode machine which runs on electric power where a catenary is available, but which can continue with diesel power on non-electrified tracks. New Jersey Transit has 26 of these modern machines. They are in use since 2015.
