The Innovia APM 100 is an evolution of Westinghouse's previous people mover vehicle, the C-100. Bombardier's intended successor to the Innovia APM 100 is the
Innovia APM 200 (originally simply known as the Innovia), which made its debut on
Dallas-Fort Worth International Airport's Skylink APM. However, the Innovia APM 100 continues to be offered by Bombardier and will remain in service at many airports for years to come. In addition to being used at many airports, the Innovia APM 100 is used on the

History
The Innovia 100 APM people mover vehicle is a modern version of the Westinghouse C-100 people mover first built by the
Westinghouse Electric Corporation
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse and headquartered in Pittsburgh, Pennsylvania. It was originally named "Westinghouse Electric & Manufacturing Company" and was ...

as a prototype to demonstrate their people mover technology in 1965. Westinghouse marketed the people mover system as an urban transit system and had hoped to build a fully-functioning system in Pittsburgh. However, political leaders held opposing views on the prospects of a rubber-tired mass transit system and plans to implement this system were rejected.
Despite this, Westinghouse would see success with their people mover system at airports. In 1966, they were contracted to build a
people mover system for the new terminal at
Tampa International Airport

. This would be the first time an automated people mover system was used to transport passengers within an airport terminal. The Tampa airport system included eight first-generation Westinghouse C-100 vehicles when it opened in 1971. Two years later, Westinghouse completed its second airport people mover system, the
Satellite Transit System, at
Seattle-Tacoma International Airport.
In 1980, Westinghouse people mover systems were opened at

Hartsfield Atlanta International Airport. The system in Atlanta (known today as
The Plane Train), is one of the world's most heavily used people mover systems in the world. These systems used second generation C-100 vehicles, which has been the primary design of the vehicle ever since. The C-100 would be installed at more airports throughout the 1980s.
In 1986, the Westinghouse C-100 made its debut on its first urban people mover system, the
