A PARTIALLY constructed building that is part of Scotland's biggest rail project faces being torn down.

And the estimated cost of the U-turn at Queen Street Station is between £3million and £15million, according the the Scotsman.

Transport Scotland has ordered a review of the building in the car park, which is for rail staff and shops.

This is part of expanding the station is to accommodate brand new electric trains on the main line to Edinburgh this year.

Trains are due to start running in March, however other delays to the £800m Edinburgh Glasgow Improvement Programme (EGIP) have already pushed back completion of the station until 2020.

It is believed that officials are considering a larger development in the car park.

This comes despite numerous plans by Network Rail going back 12 years, which were later cut back.

Network Rail said: “We have paused work while we explore potential changes to the scope with the Scottish Government.

“If the discussions result in a new development, then we’d most likely have to remove the steelwork.”
