I got what you mean. I understand that buses will operate on
Sundays and public holidays schedule on public holidays.
In the case of service 401, the operating hours on Saturdays is
from 2pm to 10pm while on Sundays and public holidays is from 10am
to 8pm.
So on last Saturday (01 May), the Sundays and public holidays
schedule instead of the Saturday schedule is applied. This means
that the last bus from Bedok interchange departed at 8pm instead of
10pm. My question is, is it feasible to extend the last bus
departure time from 8pm to 10pm on public holidays which falls on
Saturdays and Sundays, I believe there's still people going to and
fro East Coast park after the last bus at 8pm.
