Installing a west facing central bay at Oxford Road does seem to be quite a change from the original plan. There’s also no options if either of the 2 through platforms are blocked. I was surprised by the original plan not having any bay platforms at Oxford Road as turning services round there would seem to take pressure of the double track section at the Oxford Road bridge. I’ve got used to the idea of 4 through platforms now though. I assume any change to the original plan would take more time?
