My hon. Friend is absolutely right that this is a complex scenario, but there really is no need for us to be in one of the troughs in the supply chain at the moment. Chiltern Railways has massive overcrowding because its stock is the oldest fleet, and it is desperate for more trains on the network. We also have East West Rail about to launch with borrowed diesel trains, rather than the new hybrids or hydrogen trains that are fit for the modern age. As my hon. Friend looks at what can be brought forward, will he prioritise Chiltern and prioritise getting the trains that people want to see on East West Rail?
