What is difference between monorail and birail?

Monorail and Birail are both elevated railway systems, but they differ in their design and construction.

Monorail

* A monorail system consists of a single rail that supports and guides the vehicles.

* The vehicles are suspended from the rail and can move freely in both directions.

* Monorail systems are typically used in urban areas for public transportation.

Birail

* A birail system consists of two parallel rails that support and guide the vehicles.

* The vehicles are mounted on the rails and have wheels that run along the tracks.

* Birail systems are typically used for long-distance travel and freight transport.

Here is a table summarizing the key differences between monorail and birail systems:

| Feature | Monorail | Birail |

|---|---|---|

| Number of rails | 1 | 2 |

| Vehicle suspension | Suspended from the rail | Mounted on the rails |

| Typical use | Urban public transportation | Long-distance travel and freight transport |

Ultimately, the best choice of elevated railway system depends on the specific needs of the project.
