Oxford and Cowley by 2019? Ha ha! good luck with that considering the entire GRIP process from start to finish is normally a good 4 years at least. The other dates for completion for phase 2 are no different to what they are now from what I can work out, so not sure where the acceleration is. I also don't understand the bit about the HS2 interface at Calvert, there is no reason why HS2 couldn't deliver it on behalf of E-W or vice versa depending on who is there first?
