TRAINS have resumed service on the Midland Line after a brief cancellation this morning.
Services between Midland and Perth Stations were cancelled at 5.30am due to a technical issue.
Replacement bus services operated between the two stations to assist stranded passengers.
Transperth announced the problem was fixed as of 6.30am and normal service had resumed.
Commuters were advised they may experience minor delays as the service returned to normal ahead of morning peak hour operations.
