Or indeed not bothering with building EWR, and just running direct Oxford - Cambridge trains via Bond Street. A government promise achieved below budget and ahead of time...Now there's an idea...
...but why stop there? With some skullduggery at Stratford EWR could run through the Crossrail tunnels at Paddington at turn off towards Cambridge.
An Outer Circle! What's not to like?
(PS - I don't think there was ever an 'aspiration' on the part of EWR to run through to Reading - more the result of a feverish imagination of a poster here or elsewhere or even, heaven forbid, a politician trying to look relevant).
