Great Western Railway

GWR is a British rail operator that provides passenger train services across the United Kingdom. Its core offering consists of regular and intercity rail connections linking major cities and towns in the south‑west of England and south Wales. The company operates under the franchise agreement for the Great Western rail network, managing both commuter and long‑distance routes. Services include standard class, first class, and optional catering facilities on selected trains.

In April 2018 GWR disclosed a security incident in which automated login attempts were made against customer accounts, resulting in roughly one thousand successful breaches. As a precaution, the operator reset passwords for more than one million accounts to prevent further unauthorized access. Although encrypted banking data remained unaffected, customers expressed concern about the legitimacy of the reset notifications due to an unfamiliar sender address. Analysis indicated that the low success rate of the attempts suggested attackers relied on credential stuffing from previously compromised external sources.

GWR operates the Intercity Express Train fleet that provides high‑speed services on the Great Western main line. It also manages sleeper services such as the Night Riviera between London Paddington and Penzance. The company is regulated by the Office of Rail and Road and must meet performance targets set by the Department for Transport. Its role as a franchise holder entails responsibility for station facilities, timetable planning, and customer service standards across its network.
