RAIL users across Bromsgrove, Redditch and South Birmingham are facing delays and cancellations because of a signalling fault between Longbridge and Birmingham New Street.
Network Rail has now repaired the equipment but commuters will still face delays of up to 15 minutes.
The 2.12pm and 2.51pm from Bromsgrove to Four Oaks and Lichfield, via Birmingham New Street, were cancelled, along with the 3.51pm.
Disruption is expected to last until 4pm today.
