SCOTLAND’S troubled a Caledonian Sleeper train trains are set to face further disruption after guards and stewards overwhelmingly voted to strike.

Rail union RMT said members had voted by a margin of 10 to one to down tools on a turnout of over 80 per cent.

The union has now upped the pressure on outsourcing giant Serco, which operates the service, by calling for the route to be renationalised.
