RAIL workers could go on strike over disruption to services at Nottingham Station caused by major re-signalling works.
The majority of services into and out of the station will cease on July 20 for six weeks while a £100m upgrade of its signalling and track takes place.
The RMT union has now announced it is balloting members over possible industrial action.
It says there has been a "comprehensive breakdown in industrial relations" between the union and East Midlands Trains.
The union claims a number of issues are unresolved, including a "total failure to consult with the union" over the re-signalling works.
RMT General Secretary Bob Crow said: "The union remains available for talks aimed at securing agreement but the company should be in no doubt as to the level of anger that their actions have generated amongst members."
The union has balloted members – which include train managers, senior conductors, and station staff – who have until July 11 to respond over possible strike action.
An East Midlands Trains spokesman said the company was "astounded" at the ballot, over "a hotchpotch of issues that don't even exist".
The spokesman said: "Planning for the Nottingham improvement work has been taking place for over two years and our employees have been fully involved in this planning for many months."
