SEPTA's 25 Hz traction power system uses the same 12 kV voltage on the catenary in Northeast Philadelphia.

These contracts do not include track, stations, or electrical infrastructure such as traction power, control systems and catenary.
13.
The concept of a six-axle locomotive did not permit the application of more than 1620 kW of traction power.
14.
Two out of its 14 turbines are connected to two single-phase generators to supply Amtrak's 25 Hz traction power system.
15.
This marked a significant improvement in the traction power available to CI?and enabled the acceleration of express passenger services.
16.
Amtrak's 60 Hz traction power system in the Northeast Corridor between New York and Boston also uses split-phase power distribution.
17.
However, many traction power stations have replaced their generators over time to use three-phase generators and convert into single-phase for transmission.
18.
During that time, the single-phase AC system had been widely used for their traction power networks beside the direct current system.
19.
A few years later a third prototype 11852 was built, which was quite similar to 11851 but with increased traction power.
20.
In addition to subway / SRT train control, the facility monitors traction power, security, fire safety, communications, ventilation and mechanical systems.
