Great Western Railway Routes

I want to support the point the hon. Gentleman is making. The incident he is talking about was the most extreme example of damage to a piece of major rail infrastructure. It is no fault of Great Western Railway, but I travelled up from south Wales by bus for part of my journey today because of flooding on part of the line. Okay, that is an extreme event, but we are having more and more. There is also regular flooding around the Severn tunnel. Does the hon. Gentleman agree that we need to be absolutely sure that we have a resilient railway structure, as well as having electrification?
