Monorail (315 words) |
 | A monorail is a metro or railroad with a track consisting of a single rail, as opposed to the traditional track with two parallel rails. |
| Monorail systems have been built in many locations around the world, many of them on elevated tracks through crowded areas that would otherwise require the construction of expensive underground lines or have the disadvantages of surface lines. |
| A short monorail was built in Seattle for the Century 21 Exposition in 1962 and its expansion is currently being discussed. |

| The KL Monorail in Kuala Lumpur, a colourful straddle-beam monorail |
| The most common type of monorail in use today is the straddle-beam monorail, in which the train straddles a reinforced concrete beam in the range of two to three feet (~0.6-0.9 m) wide. |
| The term 'monorail' is often applied by members of the public to any modern elevated railway, particularly automated ones such as the Docklands Light Railway, Vancouver SkyTrain and the JFK AirTrain, but this usage is erroneous; these systems use the same twin rails and electric third rail as most underground metros and some main-line railways. |
