Shuttle train

A shuttle train is a train that runs back and forth over a short route.^[1][2] Shuttle trains are used in various ways in different parts of the world. They can be used to carry passengers, freight (including accompanied cars/buses/trucks), or both.

For passenger trains they are generally one of two types:

• a branch line or other short distance line, generally with frequent services, where trains travel back & forth over the short line; or
• a supplementary service to cater for high passenger numbers on a short portion of a railway line, either during rush hours or other specified times such as before or after major events (concerts, sports, etc).

An airport shuttle train runs between an airport terminal and one or more other locations such as another airport terminal, railway station or carpark - often a combination of these locations. These are generally in the form of a driverless people mover/automated guideway transit (AGT).

A car shuttle train is used to transport accompanied automobiles, and usually also other types of road vehicles, for a relatively short distance.

On car shuttle train services, the occupants of the road vehicles being carried on the train usually stay with their vehicle throughout the rail journey.
