There are 3 TOCs which could theoretically operate it - GWR, WMT or Chiltern.
Options would I guess be:
- Extend the GWR Didcot-Banbury (roughly 0.5tph at present) back to Moor St
- Extend the hourly WMT Dorridge terminator to Oxford, with GWR operating a shuttle Oxford-Didcot only, or all the way to Didcot
- Entirely new service in addition to what runs now which could be any of the three but less likely to be GWR
It wouldn't I suspect be via Bicester as that would require a reversal.
