Mark VI monorail


The Mark VI monorail is a monorail train used in the Walt Disney World Monorail System and the Las Vegas Monorail. The Mark VI started replacing the Mark IV monorails at Walt Disney World in 1989, replacing the final Mark IV by 1991. The Mark VI later replaced the two ex-WDW Mark IV monorail sets of the Las Vegas Monorail in 2004. The Las Vegas M-VI versions of the trains differ from the Walt Disney World trains in physical appearance and the fact that they are automated, a trait the Walt Disney World monorails lacked until their automation.

Train specifications

Each train has eight electric motors operating on 600 volts DC to produce 100 hp each. The motors also serve as brakes via dynamic braking and send power to resistor banks located between each car. Walt Disney World's trains have been fitted with a governor which limits their maximum speed to 55 MPH ; however, Disney regulations permit only 40 MPH.

Suspension

The Mark VI Suspension consists of a load tire and guide tires. The load tire is a Michelin XTE2 445/65R22.5 size tire, and rides along the top of the beam and provides traction for the movement of the monorail. The guide tires are just that; they guide the monorail on the beam. They are filled with nitrogen to help reduce the chance of fire in the event of tire failure.
