DOO mirrors are certainly fitted at all the stations on that route.

Watford / Snorbens has got mirrors but the 321 is crewed.

I'm probably wrong but I thought mirrors are an aid to driver to see
guard but DOO needs CCTV ?

The WAGN services through New Barnet and Oakleigh Park down to
Moorgate and Kings Cross used to have CCTV, but it was removed and
replaced with mirrors. I don't know what the significance of that
was.
