TRAIN services in and out of Portsmouth Harbour are back up and running after a signalling fault caused misery for early morning commuters.
The problem was reported to Network Rail at about 4.50am.
A number of trains had to be cancelled or redirected, with services unable to terminate in Portsmouth Harbour, while engineers fixed the system.
The disruption affected scores of passengers attempting to leave the city, with replacement bus services being offered to some by South West Trains.
The repairs to the signalling system took about an hour and a half and normal service was able to resume shortly after 6am.
A spokesman for railway operator Southern thanked passengers for their patience during the disruption.
He said: ‘We would like to apologise to our passengers.
‘We know that Network Rail did their best to fix the signalling fault as quickly as possible to get our passengers back on the move.’
