FirstGroup plc operates extensive passenger transport networks across the UK and Ireland. Its First Rail division is the country's largest rail operator, managing contracted services such as Avanti West Coast and Great Western Railway, alongside open-access passenger routes like Hull Trains and Lumo. The First Bus division operates a fleet of approximately 4,900 buses, serving local communities and providing long-distance coach services. Following the divestment of its North American operations, including Greyhound and First Student, in 2021, the company is entirely focused on its domestic markets. FirstGroup is also actively investing in the decarbonization of its fleet, rolling out zero-emission buses and electric depot infrastructure to support sustainable public transport.
