The difference between single-source trolleybus and Shuang Yuan trolleybus

The difference between single-source trolleybus and Shuang Yuan trolleybus lies in the different power supply modes.

Single-source trolleybus refers to the use of a bottom conductor as the only power supply, and the current is transmitted from this conductor to the vehicle, and then to the car body through the contact between the wheels and the ground to drive the vehicle. Shuang Yuan trolleybus refers to the use of two bottom wires as power supply to supply power to the motors on the left and right sides of the vehicle respectively. When one conductor fails, the vehicle can still get power from the other conductor to ensure normal operation. The main difference between them lies in the different power supply modes.

Tram is a new type of urban rail transit, which transmits electricity by radio or other technologies without laying traditional tracks.
