When I purchased my rail ticket from Godalming to Ealing Broadway the other
day, the route I could take was "any permitted". I was musing on my way
[weekday early morning] via Waterloo / Bond Street and onto Ealing Broadway
whether an alternative that could have been used was changing at Woking onto
the Railair coach link to Heathrow Central and then the Heathrow Connect
service to Ealing Broadway. Even if permissible, I wondered if it would have
been quicker than the actual route taken. Be interesting to know the answer to
that one.

You might also want to look at Waterloo-Paddington-Ealing Broadway. P-
EB is under 10 minutes.
