What is happening regarding rail access to LHR T5 ? Are they extending both the Underground and the Heathrow Express ?
Will the Heathrow Express go from the central station to T4 and then to T5, or will it be a split service after the central station ? If it goes via T4 first before T5, it'll be almost 30 minutes......
As for the Underground, will it go from T4 to T5 before looping back to T1/2/3 ?
As for the Heathrow Express, it seems to me an attractive solution would be a through Paddington to Reading service VIA Heathrow T1/2/3, T4 and T5, which would solve the problem of access to the west. But that would cost millions of billions.
