GCC should be publishing its ten year transport strategy next year - a little like Edinburgh's comprehensive plan that was released earlier this year: https://www.edinburgh.gov.uk/news/article/12714/all-aboard-for-2030-a-greener-healthier-better-connected-capital
I expect the headline takeaway from this will be a formal recommendation/go ahead for the Connectivity Commission's "Glasgow Metro" plan - a new network of light rail / tram lines. Fully expect the Airport to City Centre tram line will get the nod (and necessary funding) from Transport Scotland around that time too.
