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.

The team start work on cleaning up the station’s disused Victorian Platform to get it ready for renovation, but the clear-out comes with its own issues. Up on the concourse, Transport Police tackle drug issues around the station, and station staff receive life-saving training. A special unveiling takes place to honour war veterans, and out on the tracks, the engineering team tackle one of the biggest sections of work in the Argyll Line closure.

Station staff work to raise awareness of homelessness by hosting a sleep out on the concourse, while staff benefit from a visit from a therapet to boost mental health. The maintenance team deal with a blocked toilet, and the engineering teams below ground work to carry out vital repairs to waterproof the tunnels. Paul explores the fascinating history of Glasgow’s shipyards and their link to the railway, and Jackie and Drew receive exciting news that will have a big impact on the station tours.

The station tours are a man down, putting extra pressure on tour guide Jackie. Outside the station, the engineers at Polmadie depot are working against the clock.

Easter weekend is here, bringing with it rival football fans and bank holiday revellers who put the station staff to the test, and a there’s a new police dog in training.

The Central team adapt as the station’s low level closes for eight weeks as part of a huge engineering project. Outside the station, the Network Rail helicopter takes to the skies.
