Latest estimates predict that the Borders Railway will not re-open until at least 2015 - a year later than planned. Project officials also believe that costs for the Tweedbank to Edinburgh route will be around £50 million higher than the £295 million budget.
Transport Scotland didn't comment on the estimates, but confirmed that they are currently finalising the commercial terms of the contract to build the line, and expect that process to be finished in the next few weeks. The Borders has been without a railway since the Beeching cuts of 1969.
