The ALP-46 is one of a German 101 series derived and Bombardier built in Kassel electric locomotive of the transport company New Jersey Transit (NJT), which in turn moves the York New suburban is used. The ALP-46 mostly runs with double-decker cars in trains that travel up to 160 km / h on the north-east corridor .
The second series NJT ALP-46A is designed for 201 km / h (125 mph).
history
In 1983, NJT took over suburban traffic on all Conrail lines in the state of New Jersey with its own vehicles and staff. From 1990 to 1997 32 thyristor locomotives ALP-44 were procured, which were derived from the Swedish Rc6 . In order to be able to cope with the constantly growing number of passengers , NJT was looking for new, more powerful locomotives . At the end of January 2000, NJT and ABB signed a contract for the supply of 24 three-phase AC locomotives, which was increased by 5 locomotives in September 2001. The additional locomotives were to be used for the clocker service taken over by Amtrak ; however, this fast regional train on the north-east corridor was discontinued after a short time.
In February 2008, NJT ordered 27 additional locomotives of an improved variant of the ALP-46 series, which is referred to as ALP-46A, for 155 million euros. Delivery was planned for autumn 2009. The order was increased by nine in the summer of 2009 to replace the oldest locomotives of the ALP-44 series . On April 5, 2011, the last locomotive of the second series was delivered.
For the 40th anniversary of NJT, three so-called Heritage Locomotives in the livery of earlier sub-companies were presented in October 2019 , including NJT ALP-46A No. 4636 in the brown and gold color of the Pennsylvania Railroad .
Constructive features
The mechanical part is based on the DB class 101, but had to be adapted to American conditions. The box had to be reinforced so that it can withstand the higher pressure forces at the coupling level compared to Europe. The bogies had to be adapted to the higher locomotive weight. The wheelbase stayed the same. but smaller American standard wheels (new: 1118 mm; worn 1046 mm) were used. The gear ratio was changed so that the starting tractive effort could be increased to 319 kN at the expense of the maximum speed. With a weight of 92.5 t, the ALP-46 is a light locomotive by American standards.
The ALP-46 generates 319 kN pulling force when starting and has an output of 5300 kW on the wheel. Traction motors and integrated total drive (IGA) were taken over from the 101 series with small changes .
The ALP-46 is a multi-system locomotive and can run under the following three AC systems :
- 25 kV 60 Hz (Great Notch and Gladstone Branch)
- 12.5 kV 60 Hz (originally Coastline to Long Branch, Metro-North Railroad)
- 12 kV 25 Hz (Northeast Corridor)
In contrast to the 101 series, the ALP-46 has a group drive , which means that the two traction motors of a bogie are supplied by the same inverter . The freed-up inverter is used for the three-phase train busbar to supply the cars with electrical energy.
ALP-46A
Compared to the ALP-46, the ALP-46A has some changes:
- The top speed was increased to 200 km / h and the power to 5.6 MW;
- The converters are designed using IGBT technology with water cooling.
- Single-axle drive in which each drive motor is assigned its own inverter
