They will have no effect at all on the journey times. This is about delivering the project by and large as planned. HS2 is more about capacity than it is about journey times. This is about addressing the real capacity issues that we have on our rail network, particularly between Birmingham and London.
The most significant other change concerns the Heathrow Express depot. It is currently located at Old Oak Common, but it needs to be relocated in order to construct the new Old Oak Common station. It was originally intended to be moved to another site nearby, but more detailed operational work undertaken by Network Rail since the Bill’s deposit has revealed that that site would not work operationally. We therefore propose to relocate the depot to a site in Langley, near Slough.
