Until 1 April 2007 there were only three trains per hour between Fratton and Portsmouth Harbour with the remaining services terminating at Fratton and passengers using a replacement bus service. After 2 April 2007 there were five trains per hour running between Fratton and Portsmouth - three South West Trains services, one Southern service and one Great Western Railway service with some services still terminating at Fratton with passengers forced to change to continue their journey. The 'six-week project' was eventually completed in October 2007 - some ten months after it started.
