Train services through Reading Station are in chaos tonight and there could be problems tomorrow.
It follows disruption this morning when engineering works overran to allow the opening of the first phase of the new £900m station. A broken down train and signal problems added to the disruption.
It has now been revealed that because trains were left in the wrong place some drivers can no longer work trains because they would be in breach safety rules to limit how long they can spend in the cab.
Trains to Newbury, Paddington, Basingstoke and Oxford have been hit with cancellations.
Part of the station remains closed to allow for more work but it appears that too many trains have been timetables to run than than the station can cope with.
Managers are meeting tonight to consider reducing the planned service for tomorrow.
