Alfa Pendular is the name of the flagship Pendolino high-speed tilting train of Portuguese state railway company CP.
[1] It connects the cities of Guimarães, Braga, Porto, Aveiro, Coimbra, Santarém, Lisbon, Albufeira and Faro, among others at speeds of up to 220 km/h (135 mph).
Beginning 2017, the trains were refurbished, introducing new interiors, livery, seating and features such as Wi-Fi and power outlets.
The combination of the resulting high cornering velocity and the tilting movement of the carriages helps ensure a comfortable ride for the passengers, although the jostle and sway compensating for track irregularities may cause "motion sickness" in those susceptible.
The use of this train did not require particular modifications to the existing rail network, but it is expensive in terms of maintenance of the rolling stock because of the complexity of the tilting system.
