Bombardier Transportation won a contract from the city of Phoenix to extend an automated people mover system at Phoenix Sky Harbor International Airport.

The agreement covers a 2.5-mile extension to the airport's rental car center, two new stations, an expansion of the system's maintenance facility and 24 additional vehicles. The contract is valued at approximately $305 million and includes options for three additional vehicles as well as for various vehicle retrofits and upgrades.

Under contracts awarded in 2009 for Stage 1 of the system, Bombardier designed and supplied all electrical and mechanical equipment, including automatic train control technology, a maintenance facility and a fleet of 18 vehicles. In addition, Bombardier has provided operations and maintenance services since the system opened in 2013.

Bombardier says the Phoenix system has achieved over 99.5 percent availability each year since the system opened. It has also reached 100 percent availability in a given month six times, most recently in January.
