A signalling problem has disrupted train services between Oxford and Didcot Parkway this morning.
First Great Western has provided a replacement bus service for passengers after the problem emerged.
A statement on the company’s website said: “Engineers are working as fast as possible to restore services to normal.
“Short notice cancellations and delays of up to 30 minutes can be expected.”
