I thank my hon. Friend for sharing with the House his superb knowledge of the vegetation on the Great Western main line in Devon and Cornwall. His point absolutely rams home the message that a tree falling over, a cow breaking out of a field, or a small amount of earth moving at a critical point can close huge parts of the network. That is why it is so important to hold this debate about resilience. In addition, the cross-country services have been cancelled at Dawlish again today. I must say that that is not due to the line but to a fault with the trains, but that again brings home to us the vulnerability of some key routes and networks on which many people depend.
I hope that this debate will not be about being negative and having a moan. We could all spend the next few hours whingeing and sharing our stories about various poor train journeys. One that sticks in my mind was when I and my hon. Friend the Member for Taunton Deane (Rebecca Pow) got on a train that had what was charmingly described as a “toilet spill”, which was particularly interesting. Being negative will not achieve anything: it may make us feel a bit better to get a dreadful journey off our chests, but it will not actually make a difference.
