Ascott-under-Wychwood railway station is a railway station serving the village of Ascott-under-Wychwood in Oxfordshire, England. It is on the Cotswold Line. The station, and all trains serving it, are operated by Great Western Railway. West of the station is a level crossing, controlled by Ascott-under-Wychwood Signal Box, which also oversees the adjacent end of the double-tracked section of the Cotswold Line. Under proposals to extend the doubling of the route, the signal box was to be removed but budgetary constraints on resignalling led to that proposal being revised.
