Currently there is an 05:26 (Mon-Fri) from Aylesbury, that arrives in
Paddington at 06:39 and which leaves as empty stock. There is then an 11:28
from Princes Risborough that runs on Mon/Tue/Thu/Fri to Paddington, arriving
at 12:29, and on Wednesdays only to Marylebone, arriving at 12:22. The
return services depart from Paddington to Princes Risborough at 12:55
Mon/Tue/Thu/Fri and from Marylebone at 13:00 on Wednesdays only.

From 10th December, this becomes 10:01SX from Gerrards Cross to
Paddington (calling Denham Golf Club, Denham and West Ruislip), and
11:11SX from Paddington to Princes Risborough (calling West Ruislip,
Gerrards Cross, Beaconsfield, High Wycombe and Saunderton).
