First Great Western will continue to operate a modified train timetable tomorrow, due to the wintry weather.

However, more services are planned to run than today, with the first trains due to operate on the Oxford-Bicester Town branch line for three days and a key Didcot to London morning commuter train reinstated after being cancelled two days running.

The 7.28am departure from Didcot Parkway is reinstated but the 7.19am departure will again be suspended.

FGW aims to run full services between Oxford, Reading and London, on the Cotswold Line between Oxford and Worcester, and on the Cherwell Valley stopping service between Oxford and Banbury but says all services could be affected by short-notice alterations and cancellations.

In the south of the county, a special timetable will be in force on the Henley-Twyford branch line. See the FGW website for details.

Passengers travelling between Didcot, the South West and South Wales are being advised to check train times before setting out to stations.

A reduced service will be in operation tomorrow between Cardiff and London, with fewer services calling at Didcot.

Trains to Bristol are suffering severe disruption at present due to an explosion at a bottled gas depot earlier today near the line in Bristol. Trains cannot serve Bath and Chippenham, with replacement buses operating. Problems may continue into the morning.

Chiltern Railways will operate a revised timetable at Banbury, Kings Sutton, Bicester North and Haddenham & Thame Parkway stations tomorrow. See the firm's website for details. Advance tickets, dated for travel tomorrow only, will be valid on any Chiltern train within three hours of the time booked.

The county's other train operators, CrossCountry and Wrexham & Shropshire aim to operate normal timetables tomorrow, though again they may be subject to alterations and cancellations.

The Oxford Bus Company plans to operate as near-normal a service as possible on all routes but road conditions mean that a number of services may have to miss out sections of routes on estate roads and in villages in and around Oxford that have not been salted or cleared by snowploughs. For the latest information, see the firm's website, or call 01865 785400.
