Erm, then the erm, the insistence of the driver's conductors was they didn't like the long periods of duty  they erm, they wanted the new set up so I introduced what we call straight duties, narrowed the relief portion, so they didn't go home for a meal, they had about a half an hour off, so they were able to get their eight hour duty done in a shorter period and they'd probably finish about two instead of half past three, four o'clock.
