Mark VI Monorail

The Mark VI Monorail is the current monorail train model used on the Walt Disney World Monorail System. It was brought into service in 1989, entirely replacing the previous Mark IV fleet in 1991. The trains were built by Bombardier Transportation of Canada. The Mark VI Monorail is also used on the Las Vegas Monorail, known by the abbreviated name MVI. Before that line was extended, it was known as the MGM Grand-Bally's Monorail, which used two former Walt Disney World Mark IV trains.
