What is the voltage on the contact shoes of the car?

The voltage on the contact shoes of the car is identified as 600 volts DC, which is standard for many transit systems, including various rail systems that use electric traction. This voltage level is designed to provide sufficient power to operate electric trains efficiently, allowing for effective acceleration, speed maintenance, and overall good performance.

Low-voltage systems, like 120 and 240 volts DC, are typically used for smaller applications or different types of electrical systems, which do not meet the power requirements of rail vehicles. The 480 volts DC option is also not standard in most rail systems, as it does not provide enough power for large electric trains, and systems are commonly engineered to utilize the higher voltage of 600 volts for operational efficiency. Hence, 600 volts DC is established as the effective voltage for the contact shoes on the car.
