Work is currently being carried out on the old train tunnel that runs between Kelvin Bridge and the Botanic Gardens.
It has been reported that this is to prepare the site for shooting of the HBO Max film, which is currently being shot in the city.
Part of the tunnel, next to the Inn Deep pub in Kelvin Bridge, has been opened up, with security personnel watching the entrance and signs warning walkers that vehicles are using the area.
Meanwhile, work is also being carried out the old train station in the Botanic Gardens.
The tunnel was part of the line that ran between Stobcross to north west Glasgow, with stations in Kelvin Bridge, the Botanic Gardens and Kirklee.
The line closed for good in the ‘60s.
Production has now started on the shoot in Glasgow. Star Leslie Grace, who plays the titular character, has been spotted in the Parnie Street and King Street area, which has been closed off for shooting.
Michael Keaton is due to don the famous Batman cowl for the first time in decades, while Brendan Fraser will play villain Firefly.
