The ALP-45DP is a dual-mode electro-diesel locomotive, the locomotive uses two high-speed, twelve-cylinder Caterpillar 3512HD diesel engines rated at 2,100 hp (1.6 MW) each. The systems for the two engines are independent allowing the locomotive to operate on one engine in case of failure or under low load. The engines are capable of shorter startup times from idle to load (100 rpm/s) than traditional medium speed diesel engines. Under diesel power, each engine powers a MITRAC TG 3800 A alternator having an output of 1700 kVA @ 1800 rpm. Power output is reduced from 6,700 hp (5.0 MW) (including HEP) in electric mode to 4,200 hp (3.1 MW) in diesel mode. In addition to taps for the traction inverters, the locomotive transformer supplies 1100 kVA and 140 kVA for head-end power and locomotive auxiliary power. HEP is maintained when changing power modes, due to the fact that the pantograph is not dropped until the diesels have been started (when changing from electric to diesel), and the diesels are not shut off until the pantograph has contacted the wire (when changing from diesel to electric). In either case, the changeover takes approximately 100 seconds. The dynamic and regenerative braking system is capable of routing power generated by the electric brake to HEP and locomotive auxiliary power requirements in addition to the dynamic brake resistor.
The locomotives meet CFR and AAR crashworthiness standards. The diesel engines meet Tier 3 EPA emission standards, and can be upgraded to Tier 4 standards. Additionally the engines can be converted to run on natural gas, or they can be replaced with hydrogen fuel cells, batteries can also be added that will enable hybrid operation with regenerative breaking.
The coaches feature an aluminum body on a steel frame. They are 4.85 m high and 3.00 m wide, and weigh about 61,000 kg. Depending on car design and seating configuration, seats are available for between 136 and 162 passengers, along with standing room, all coaches feature a washroom on the lower level. The coaches have two pairs of doors on each side which allow the entire coach to be emptied in 90 seconds. The coaches also have electrical outlets for laptop computers and other devices along with small tables.
The cab car is placed at the end of the train and features a full cab built into the end of the coach, from which the train's locomotive can be remotely controlled. This allows for push–pull operation with a faster turnaround time for trains, by avoiding having to physically turn around the train or locomotive.
A Genset locomotive is one where a number of smaller diesel engines are used rather that a single large engine. The excess engines are turned off when the extra power is not needed, this saves fuel, wear & tear, noise, pollution, etc., and should one genset engine fail, the others can keep the train going.
