PLANS to upgrade the Glasgow Subway are being developed by consultant Atkins.
The Strathclyde Passenger Transport Executive has awarded the £40 million contract to look into how to extend the underground system and transport links over the next 10 to 30 years.
The study will go on for 12 months, with recommendations expected in early 2007.
Atkins has also been appointed to look into proposed new methods of improving the ticketing halls as part of a separate contract.
A spokeswoman for SPT said: 'This is something that is in its very early stages, this feasibility study will be reported back to us next year.
There is a lot of regeneration going on down both parts of the river, which is why we are seeking ways to upgrade the transport system.' The Glasgow Subway was built in 1896 and restored to its current condition in 1980. Some 13 million people use the network every year.
