We aren't able to catch the train back to Garscadden, which would be the last of the day from the station. Although, perhaps a night in Garscadden isn't the best idea anyway!
With the public tranport network pretty much shutting down at Midnight, and no night buses until the weekend, we don't have many options. However, we do find that we can catch the last bus of the day from Union Street at Central Station, which is a First Glasgow 4 service bound for Newton Mearns (Harvie Avenue), arriving at 00:26. We ride it to its terminus, where we arrive at 01:12 on Tuesday morning.
