I believe they did. 319s also used to travel via Dorking from what I've been told, and ran on the WCML - both with guards.
Apparently, some guards didn't like working them very much because of the need to return to the cab for dispatch and the fact that you could lock yourself in (or out, I forget which) of the train very easily.
Locking yourself out of a lot of older emu stock is very easy. The internal cab door needs a number one key. If you've left it in the cab to operate the doors and end up in the passenger saloon, you'll shortly be knock ing on the driver's door at the next stop to borrow his key.
