Chiltern have made available the final timetable from October 26th and fares at Islip and Bicester. Please ignore the fares previously given both the Chiltern website and NRE (which gave a little cause for concern). Fares to/from Oxford (centre) will be published shortly.
Here is an up-to-date version of my own summary of the timetable for Islip :
Hope we all agree that these fares seem reasonable and remain competitive with most bus services.
As I write, I can hear the toot of trains on the line behind me, running for driver training.
Take care to consult the Chiltern website for weekend services as there is still much work to be completed along the track.
There is no firm date yet for the commencement of services into Oxford centre. The best recommendation is to take note of any news in the Oxford Times.
