 Consequently, phase 3, the introduction of the Squadron fleet (APT-S), did not occur, and the project was ended in 1982.Although the APT never properly entered service, the experience gained enabled the construction of other high-speed trains.The APT powercar technology was imported without the tilt into the design of the Class 91 locomotives, and the tilting technology was incorporated into Italian State Railway's Pendolino trains, which first entered service in 1987.
