[8] While most of the earlier C-100s have been retired and replaced with Innovia APM 100s, London Stansted Airport still uses 5 C-100 vehicles on its Track Transit System.
These cars are similar to the C-100s formerly used at Singapore Changi Airport's Skytrain system in the early 1990s, jointly built by Westinghouse and Adtranz (acquired by Bombardier).
