My hon. Friend is right to draw attention to this. His question refers to the brand new IC 225 rolling stock, which operates on the line from Leeds to London. The main problem occurred when snow was sucked into vents in the engine units causing overheating arid preventing the trains from being used. It is a matter of considerable concern that brand new rolling stock, only recently introduced, should be incapable of dealing with the weather conditions of the past few days.
