The Subway system in Glasgow is to close for a weekend while work is carried out.
A replacement bus service will be in operation for passengers on both circles on July 4 and 5.
The shutdown is to allow for new signalling and power cables to be installed.
Subway director Antony Smith said: “The decision to suspend Subway services has not been taken lightly.
“This is essential work that must be carried out to upgrade the Subway.
“We are taking the opportunity to do these works now as the Subway is much quieter than normal and this will cause the least disruption to our passengers.”
