Which monorail used to begin the monorail that is a 3.9 mile long monorail mass transit system?
Mark IV monorail The Mark IV monorail was a design model of straddle-type monorail trains. The design was developed by legendary Disney Imagineer Bob Gurr. Ten trains were built by Martin Marietta in 1969 at the cost of about $7 million USD each and they were used on the Walt Disney World Monorail System between 1971 and 1989 before they were replaced by the Mark VI monorail, although a few lasted until 1991. Sometime between 1991 and 1994 Monorail Coral and Lime (which had been introduced new in 1984) were sold for $3.5 million each, refurbished, and used to begin the Las Vegas Monorail operations. In 2004 Lime and Coral (now the MGM and Bally) were replaced by fully automated Bombardier MVI 4-car trains.
Manila Metro Rail Transit System The Manila Metro Rail Transit System (Filipino: "Sistema ng Pangkalakhang Riles Panlulan ng Maynila" ) also known as the MRT Line 3 or MRT-3 or Metrostar Express is a rapid transit system of Metro Manila, Philippines, and is composed of a single line that runs along the north and south lanes of Epifanio de los Santos Avenue (EDSA). Although it has the characteristics of light rail, such as with the type of rolling stock used, it is more akin to a rapid transit system owing to its total grade separation and high passenger throughput.
