I think drivers get paid depending on the hrs they drive, which
is indicated on their time sheet.
Express service between Hougang & Jurong East is not going to
ease the loads of svc 51, svc 51 loads come from in between the
route, ie pax from Hougang Ave 3 to Geylang / Chinatown, or pax
from Queensway going to Commonwealth MRT.
svc 51 takes about 2h during the day, but drivers only get 1h 20min
at night! Breaks are about 30min, which is quite long.
