^McGinnis, George. Walt Disney World's Mark VI Monorail. 2004-01-30 [2008-10-09]. The approximate 1.6 km guideway of the MGM-Grand Bally's monorail line, which used two Mark IV's, will be integrated and re-equipped. These twice-retired trains were built in the '80s and since retirement from WDW have operated for over seven years in Las Vegas.

Two dutiful Disney-built Mark IVs retired for the second time Sunday night. Previous to Las Vegas, they operated for many years in Florida at Walt Disney World... designed to be a catalyst for a larger Las Vegas Monorail, which will be achieved when the current track is connected to a four-mile system under construction. New automated Bombardier MVI trains will run along the same tracks when the new line opens in early 2004
