Against the background of a truly deplorable few months for my constituents in East Grinstead, Haywards Heath and ​Wivelsfield, the new timetable is beginning to bed down and provide a far more reliable and sustainable service, which is quite the opposite of what has been portrayed by the hon. Member for Middlesbrough (Andy McDonald) and greatly welcomed by my constituents. Will the Minister please continue to impress on the operator that the short-formed trains are really unacceptable and that we need to get back to the full-length trains as soon as we possibly can?

I thank my right hon. Friend for recognising that there has been some progress and that that has started to benefit his constituents. Obviously, we want that to continue and for that improvement to accelerate. We recognise that ensuring that there are fewer short formations, indeed no short formations, will be a very important part of that process.
