RailWorks Glasgow Airport Rail Link Add-on is now available on Steam. The Glasgow Airport Rail Link (GARL) was a proposal to directly link Glasgow Central station with Glasgow International Airport in Scotland, United Kingdom. The link was intended for completion by 2013 and would have had a service of four trains per hour running along a semi-reconstructed via Cardonald, Hillington East and Hillington West, to Paisley Gilmour Street station. It would then have branched-off onto a new purpose-built 1.2 mile (1.9 km) line taking it over the M8 motorway into the airport. Totalize Media have created numerous add-ons for rail simulation games. GARL is their most ambitious project to date featuring the whole route* covering 9km of existing track from Glasgow Central to Paisley St James and an additional 1.9km of new track between the proposed Airport Junction and Glasgow International Airport.
