Overview: The Argyll Line closure comes to an end as the engineering works are completed. Anderston station and Glasgow Central Low Level reopen, but not without some final hurdles. Outside the station, apprentices are put to the test on a night shift at Polmadie. Back on the concourse, a special tea party is organised to celebrate the Queen's jubilee, while Paul and Jackie go on a trip to Bo’Ness to put in motion their big plans for the future of the tours.
