Volvo Olympian SG Usually not the case , maybe the demand is normal so no need to use bendies for 852.
off_service SG Service 853 used Bendy Bus during NDP few years ago. However, I'm not sure how many trips it did.
sBs_boy SG Svc 853 did have bendies during the 2003 and 2004 National Day (if i didnt remember wrongly) and once during a Weekday in 2005 (seems that it was replacing a breakdown bus..)
Yaimster SG Chances are now that all the CSS buses are coming, it is enough to replace any 853 bus that is broken down .
