context_page_description: Chiltern Railways is a British train operating company owned by Arriva UK Trains that has operated the Chiltern Railways franchise since July 1996. It 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 to Birmingham Snow Hill, Stratford-upon-Avon and Oxford, with some peak-hour services extended to Kidderminster.
  Chiltern Railways also runs trains on the London to Aylesbury Line to Aylesbury, and on the Princes Risborough to Aylesbury and Oxford to Bicester branch lines.
context_section_description: Chiltern Railways operates regular services on five routes.
  The Chiltern Main Line is the core route for the majority of Chiltern Railways services and is one of two "mainline routes" operated by the company. The route links the major cities of London and Birmingham (Marylebone and Snow Hill stations respectively), passing through the towns of High Wycombe, Banbury, Royal Leamington Spa, Warwick and Solihull. Chiltern Railways operates trains along the entire line, services ranging from stopping suburban trains (e.g. London Marylebone – Gerrards Cross) to express trains running the full length of the line between London and Birmingham. The fastest timetabled journey from Birmingham to London by this route is 99 minutes (compared with 82 minutes using Avanti West Coast services between Birmingham New Street and London Euston via the West Coast Main Line). In addition to the Chiltern Railways services, CrossCountry also operates regular services on the line north of Banbury, and West Midlands Trains operates regular services north of Dorridge.
  The London to Aylesbury Line is the second "mainline route" operated by the company. The route links London (Marylebone) with Aylesbury via Amersham. All Chiltern Railways services on this route run the full length of the line between Marylebone and Aylesbury stations and call at all stations north of Amersham; most trains are extended one station further to Aylesbury Vale Parkway. The line runs alongside London Underground's Metropolitan line between Finchley Road (just north of Marylebone station) and Harrow-on-the-Hill, each operator running on separate tracks. Beyond Harrow-on-the-Hill, the tracks are shared between Chiltern Railways and Metropolitan line services. This is the only example of National Rail services using non-Network Rail tracks, and it uses a unique unregulated track-access agreement with London Underground. Beyond Amersham (where the Metropolitan line terminates), all services are operated by Chiltern Railways only.
  The other three routes regularly served by the company are all branch lines. The Princes Risborough to Aylesbury Line links Princes Risborough, on the Chiltern Main Line, with Aylesbury, on the London to Aylesbury Line. Most trains on the line continue beyond Princes Risborough to London Marylebone, which gives Aylesbury an alternative route to reach central London; however, a few services terminate at Princes Risborough. The Oxford to Bicester Line branches off the Chiltern Main Line just south of Bicester and links the town with Oxford. The line is mostly served by express services to and from Marylebone. Until December 2016, the line terminated a few miles northeast of Oxford, at the nearby Oxford Parkway station; the line was then extended to the main Oxford station. The Leamington to Stratford Line branches off the Chiltern Main Line at Hatton (a few miles west of Leamington Spa) and runs to Stratford-upon-Avon. The branch line is also operated by regular West Midlands Trains services.
  As of May 2019, its routes off-peak Monday to Friday include:
