Chiltern Railways operates commuter/regional rail passenger services from its Central London terminus at London Marylebone along the M40 corridor to destinations in Buckinghamshire, Oxfordshire and Warwickshire, as well as long-distance services to the West Midlands along two routes. Services on the Chiltern Main Line run from London Marylebone to Birmingham Snow Hill, Stratford-upon-Avon and Oxford, with some peak-hour services to Kidderminster. Chiltern Railways also runs trains on the London to Aylesbury Line to Aylesbury (with some trains terminating at Aylesbury Vale Parkway instead), on the Princes Risborough to Aylesbury and Oxford to Bicester branch lines. Chiltern Railways is part of the Arriva group, one of the leading providers of passenger transport in Europe. We strive to provide customers with a high level of service throughout the entirety of their journey with us and we extend this approach to our affiliate partners.
