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.
Loop Trolley The Loop Trolley, also known as the Delmar Loop Trolley, is a 2.2 mi heritage trolley line under construction that will serve the Delmar Loop district in St. Louis, Missouri and University City, Missouri. The line will have 10 stations and serve the Missouri History Museum in Forest Park, Washington University in St. Louis, two MetroLink stations (Forest Park–DeBaliviere station and Delmar Loop station), University City City Hall, and all the Delmar Loop attractions. The system will use two replica-historic streetcars, and one ex-Melbourne streetcar from Seattle instead of earlier plans to use two Peter Witt-type streetcars that were acquired and placed on display to promote the project in the mid-2000s. A grant of $25 million in Federal Transit Administration (FTA) funding for the project was approved in July 2010, and additional funding was secured from other sources. Construction began in March 2015 and was completed in late 2016. As of July 2017, project officials were hoping the line would be ready to open for service in mid-October 2017, after completion of testing and training.
