## Definition

a type of train system that runs on a single rail instead of two. These trains are often built high above the ground in cities or theme parks.

For teachers: a railway system in which the track consists of a single rail, typically elevated, which the vehicle either straddles or hangs from.

## Examples

- The monorail carries passengers quickly across the park.
- City planners proposed an elevated monorail to connect the airport to the downtown district without disrupting existing road traffic.
- While traditional dual-rail systems remain the standard for heavy freight, the monorail offers a sleek, space-efficient alternative for urban transit in densely populated metropolitan areas.
