My hon. Friend from nearly the city of Southend is absolutely right to mention the importance of keeping the right level of trains running. I mentioned that we funded £10.1 billion—an unprecedented amount—to keep these trains running during the covid crisis to make sure that essential workers can get to work. Of course people should not be travelling to work unless they cannot do that work from home. He will be interested to know that there have been discussions with Build UK and the Construction Leadership Council, particularly on that c2c line and concern about those trains coming into Canning Town. We will keep a close eye on this, and I have asked Sir Peter Hendy, the chair of Network Rail, to also work to ensure that we are alerted as soon as there are any signs of congestion and make sure that these lines can operate safely.
