There are a number of issues with the previously proposed GARL. Firstly it's circuitous route via Paisley Gilmour Street brought into question whether there would be any time saving on the existing bus service, and by extension, whether there would be any return on the investment. In addition, that option has largely gone now because the proposed paths have went to additional Ayrshire and Inverclyde services which are unlikely to be withdrawn to favour the introduction of a 15 min frequency airport service.
Any future airport rail link has to deal with capacity issues on the existing network, and the fact that it has to better the existing, direct, road transport link. I would suggest that any airport rail link being created in future should be based on using the old Deanside freight branch which diverges from the line at Cardonald and follows the M8 for a short distance. Whilst this would be expensive in terms of creating more infrastructure to take the new line, it at least could shadow the M8, and in making a direct route decrease journey times.
That still leaves the issue of capacity on the existing network. So either any new line could become - as others have suggested - a tram-train running right into the city centre to a terminal say somewhere like Broomielaw, near to Central. Again you have costs of building new infrastructure and potentially running a self contained rail service (unless it becomes part of the subway). But if these costs are too high, then you go back to looking at the required infrastructure enhancements for the existing network - Can Central be expanded at all? Can Crossrail be used? Can a cross city tunnel be built (v expensive).
There's not really an easy answer to the GARL issue and to top it all off, I'm not aware of anyone other than Glasgow Airport themselves really complaining about the links to the airport. And then there's the general aversion in this country to having to use two separate modes of transport. As soon as you start saying to people they have to get the train to Paisley then a bus or tram or pod, they'll switch off and go back to their car. This issue is a tough one and generally requires some effort to change public perception - although as I've previously argued improving through ticketing arrangements would hopefully see to that.
So with all that in mind, I don't see any new GARL project taking off soon, and as others have hinted, Edinburgh is the more likely to see major transport enhancements.
