Elevated railway

Elevated railways are normally found in urban areas where there would otherwise be multiple level crossings.

Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level.

[10] Another modern elevated railway is Tokyo's driverless Yurikamome line, opened in 1995.

Similar to monorails, Bombardier Innovia APM technology uses only one rail to guide the vehicle along the guideway.

APMs are common at airports and effective at helping passengers quickly reach their gates.
