AM General
Between 2001 and 2003, Metro purchased 100 Gillig Phantom coaches to replace the AM General trolleys. These coaches were delivered as "gliders," meaning that while they looked complete from the outside, internally the coach lacked a propulsion system. Metro removed the motors, propulsion controls and other components from the AM General trolleys, sent them to Alstom to be refurbished and then reinstalled them into the new Gillig bodies along with new fiberglass trolley poles from Vossloh Kiepe. The repurposing of the propulsion system from the AM General trolleybuses saved $200,000 per coach, totaling $20 million for the entire fleet.
