Straddle and suspended

The two types of monorail are based on similar engineering principles

Coupler

This device fits at the front and back of each carriage so they can be connected to create a train, the length of which can be varied depending on passenger demand.

Power

Electricity to power the monorail’s motors and the track’s signal facilities is provided via the track, so there’s no need for additional cables along the route.

Dynamic brakes

Many monorails feature dynamic braking, which uses the traction motor as a generator to transform the train’s kinetic energy into electrical energy. Other braking systems, such as pneumatic disc brakes, may be included in addition to these.

Circuit breaker

This device is installed into the monorail for safety – it will automatically stop the flow of current in the electrical circuit in the event of an accident.

Drive wheels

These large wheels transform torque into tractive force to drive the train along the track.

Traction motor

This electric motor transforms the electrical energy provided by the track into kinetic energy to power the train’s movement.

Safety systems

A computer system continually monitors the speed of the monorail, making sure it is following the speed limit and automatically slowing or stopping the train if necessary.

Guide wheels

These additional wheels are positioned either side of the track, parallel to the ground. They help stabilise the cars to keep the monorail travelling smoothly.

Monorails are an eco-friendly mode of transport and are typically much quieter than standard trains
