The developers hoping to build a rail freight terminal in Park Street have been given more time to meet government conditions, in their bid for planning permission.
Helioslough, the developer, now has until March 28 to carry out conditions, including infrastructure requirements, following a request for more time.
Last month, Eric Pickles, the secretary of state for communities and local Government said that he was "minded to approve" planning permission for the rail freight interchange subject to various conditions.
However, in a letter dated from yesterday (Thursday) Mr Pickles has agreed to a request from Helioslough to extend the original date of February 28.
A planning obligation will then be submitted, before a final decision is made.
The council wrote to Mr Pickles, urging him to reconsider his decision to agree the huge rail terminal.
