How does train traction work?
Train traction works by using electric or diesel power to drive the train wheels. In electric trains, electricity is supplied by overhead lines or electrified rail, and traction motors convert this electrical energy into mechanical energy to move the train. Traction motors are usually mounted on the train bogies (wheel assemblies) and directly drive the wheels or are connected to the wheels via gears. The control system adjusts the power supplied to the traction motors to regulate speed and acceleration.
How does train traction work?
Trains move by converting electrical or diesel energy into mechanical motion. In electric trains, traction motors receive electrical energy from an external source, such as overhead lines or a third rail, and convert it into rotational motion that drives the wheels. In diesel-electric trains, a diesel engine generates mechanical energy, which is then converted into electrical energy by a generator to drive the traction motors. The mechanical power of the motors turns the wheels, propelling the train forward.
What makes trains move?
Trains use different voltages depending on the rail system and country. Common voltages for electric trains include 1,500 volts or 3,000 volts direct current (DC) or 15,000 volts alternating current (AC). The specific voltage used depends on the railway’s electrification standards, which aim to ensure compatibility and efficiency of power distribution and locomotive operation.
The movement of a train is achieved by the rotational force generated by the traction motors. These motors are connected to the train wheels either directly or via a transmission system. When traction motors are energized, they create torque that turns the wheels. The speed and acceleration of the train are controlled by adjusting the power delivered to the traction motors. The train’s braking system, which may include regenerative braking or mechanical brakes, helps control and stop the train if necessary.
