There are bus services from Oxford to each of the major towns in the county. There are also railway connections along the Cotswold line toward Worcester, this being the only railway line across the Cotswolds. There are regular stopping trains servicing the line between Oxford and London Paddington. To go by rail between Bicester or Thame and Oxford requires a change in Banbury or London.
Buses can be infrequent to non-existent in rural areas, and often do not run an evening service.
