How Does a Monorail Work?

Answer

Nearly all modern monorails work using electric motors that are fed by dual third rails, contact wires or electrified channels attached to or enclosed in their guidance beams. However, diesel-powered monorail systems also exist. The most used 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. A rubber-tired carriage comes into contact with the beam on the top and both sides for traction and to stabilize the vehicle. The straddle-beam style was made famous by German company ALWEG.
