In October 2010, Amtrak purchased 70 locomotives at a price US$466 million, to be supplied from February 2013. As a way to comply with "Buy American" legal guidelines, the locomotives are being produced in Siemens manufacturing area with Florin, CA, with traction force as well as power apparatus becoming produced in Siemens facilities in Norcross and Alpharetta, GA.
The locomotives are generally to operate on the Northeast Corridor and also the Keystone Corridor as well as change the railroad's fleet of EMD AEM-7 and HHP-8 locomotives. In the beginning, the 20 EMD AEM-7DC items with one on one present traction force engines is going to be exchanged, then the rebuilt 29 EMD AEM-7AC with AC propulsion, and finally the 15 HHP-8 items. The additional 6 ACS-64 items is going to be intended for growth.
The purchase ended up being the other component of Amtrak's company-wide fleet-replacement system, following the purchase intended for 130 Viewliner II passanger cars ended up being slipped into Come July 2010. In 30 June 2011, US Secretaru of Transportation Ray LaHood reported of which Amtrak had received some US$562.9 million loan from the federal government's Railroad Rehabilitation as well as Improvement Funding system with the brand new locomotives.
Amtrak and Siemens unveiled the initial several concluded locomotives with 13 May 2013. They're becoming tested during summer season 2013—two at the Transportation Technological innovation Center in Pueblo, CO, and another on the NEC—and will probably enter in revenue services in fall 2013.
The structure will depend on the EuroSprinter and also the Vectron platforms, the bodies is often a monocoque design with essential supports as well as sidewalls. Considerable structural adjustments on the design and style were being meant to comply with U.S. AAR S-580 Train engine Crashworthiness Specifications including crumple specific zones, structural strengthening of the pickup truck's cab, as well as anti-climbing features; providing a heavier train engine compared to Eu Eurosprinter/Vectron models.
They can perform by 12 kV 25 Hz, 12.5 kV 60 Hz, and 25 kV 60 Hz electrical power provides, and still have an overall total electrical power involving 8,600 HP (6.4 mW). The locomotives are created to allow to increasing 18 Amfleet cars to maximum speeds of up to 201 km/h (125 mph) on the Northeast Hallway in a very very little above nine moments, with train locomotives involving nine Amfleets having a pair of and a half moments to succeed in identical speed. They have got advanced safe practices systems, including specialised couplers meant to keep train locomotives by moving above, jackknifing, or maybe derailing after a accident. Moreover, the modern locomotives tend to be more energy-efficient compared to people who they change, as well as don't have vibrant braking grids simply 100% regenerative braking, determined by grid receptiveness. Power created from the brake pedal are often helpful to meet HEP wants, even more cutting down present bring from the grid.
Just about every train engine has a pair of power converter items with several IGBT structured, h2o refrigerated output inverters every converter. 2 of the inverters electrical power the traction force engines; another product provides head-end as well as additional electrical power. The HEP/auxiliary inverters are generally dual-redundant as well as similar (rated 1, more than two hundred hewlett packard or maybe 1, 000 kW), making it possible for the train engine to be in service should just one inverter are unsuccessful en route. The train engine bogies are generally fabricated metallic styles, with low-lying traction force inbound links as well as heart pivot flag. The traction force engines are generally frame-mounted, with torque fed by using a hollowed out the whole length get. Train engine braking is actually triggerred by simply cheek positioned compact disk brakes with every wheel.
