Normal service between Didcot Parkway and Reading will not be resumed until 1pm.
Trains are now running between the two stations but may be delayed by up to 60 minutes or diverted at short notice.
First Great Western and CrossCountry services were disrupted this morning after a person was hit by a train near Cholsey.
Initially it had been estimated normal services would resume by 10am but that has been revised to 1pm.
