The possibility of rail strikes has moved a step closer as a union has set a deadline for bosses to rule out compulsory redundancies.
The leader of the Transport Salaried Staffs Association (TSSA) has given Network Rail until February 21 to commit to ruling out compulsory cuts and avoid an industrial dispute.
Manuel Cortes said he had "grave concerns" that job cuts planned by the company would undermine safety and spark a dispute with the union.
