Not in the afternoon when the OP would be travelling, unless you
can give an example.

Fast trains leaving Richmond at 15 and 45 minutes past the hour pass
non-stop through Barnes 4-5 minutes later, overtaking the Hounslow
loop services that leave Barnes at 19 and 49 minutes past the hour
- usually passing in the station or soon after.

Oh, *those* Hounslow Loop services! Yes, of course, the fasts from
Richmond overtake the clockwise Waterloo-Richmond-Hounslow-Waterloo
trains. I was looking at the Richmond-Waterloo timetable, forgetting
that from Barnes onwards you also have up trains from the other
direction in the timetable.
