Virgin's reinvention of its rail arm into a ticketing app threatens the dominance of Trainline. It is hugely popular with passengers and also powers the ticketing sites of around half of Britain's train franchises on a white label basis. Virgin is the second major challenger to Trainline. Italian train operator Trenitalia, which alongside FirstGroup took over from Sir Richard's train arm on the west coast last year, is trialling a British version of its popular software in Italy. SplitSave estimates total savings to train travellers could top £340m in 2020.
