Which country introduced the first high-speed rail with tilting technology? Italy. Italian engineers developed the Pendolino family, whose tilting body allowed fast trains to negotiate curves on existing routes more quickly and comfortably.
Fiat Ferroviaria began serious Italian tilting-train studies in the 1960s. Its first working tilting-body prototype, the electrically powered ETR Y 0160, appeared in 1969. The experimental ETR 401 followed in 1975 and entered limited public service on the Rome–Ancona route in 1976, demonstrating that tilting could improve journey times without requiring an entirely new straight railway.
The best-known production milestone came on 29 May 1988, when the ETR 450 became the first Pendolino to enter regular high-speed service anywhere in the world. “Pendolino” means “little pendulum” in Italian, referring to the train’s movement through curves.
The wording can cause confusion because other countries experimented with tilting trains earlier or in parallel. The American UAC TurboTrain entered commercial service in 1968, and Japan developed tilting express trains during the same broad period. Italy is the canonical answer for the first successful high-speed Pendolino-style service and the technology’s first regular high-speed deployment.
