The obvious place when coming in on the M40/A40 into London is
Hillingdon Underground station on the Metropolitan and Piccadilly
lines - it's not far from where the M40 crosses the M25 and becomes
the A40 - you take the turn-off for Hillingdon, and I'm pretty sure
the Underground station is also signposted from the A40 too - see this

Beware. It is a poor choice for two reasons.

First, the car park is small, and is invariably wedged (and beyond) by
mid morning. Second, the trains are very slow - there are an awful lot
of stops between Hillingdon and central London.
