Avanti West Coast, Pendolino Motor First (MF) – Era 11
During the 1970s, British Railways had pursued the concept of tilting train technology for the West Coast Main Line through the Class 370 Advanced Passenger Train concept, allowing for higher speeds to be taken through curves. By minimizing lateral forces on the passengers, the tendency to slide sideways was reduced, which in turn allowed passenger comfort levels to be maintained at higher speeds.
Even with the cancellation of the APT project, the idea of train tilt was still being considered in the 1980s for the InterCity 225 project, and again during the 1990s for the aborted InterCity 250 concept. In 1997, when Virgin Trains were awarded the franchise to operate the West Coast Main Line following the privatization of British Rail, it was on the proviso that new rolling stock was to be introduced, replacing the ageing Class 86/87/90 locomotives and Mark 2/3 coaches and so a £500 million order was placed with Alstom/Fiat Ferroviaria to construct fifty-four, eight-car tilting train sets, later increasing to nine, then eleven car sets.
The current Pendolino fleet of 52 sets comprises 31 eleven-car sets and 21 nine-car sets and all have been transferred to Avanti West Coast, the operating name for the new West Coast Partnership between FirstGroup plc and Trenitalia UK that took over the operation of the existing West Coast Main Line services on 8 December 2019, from Virgin Trains.
