It originally served on the old Express 502 route (until it was cut back by NEL rationalisation), and was fitted with a flip-dot Mobitec EDS. Less than a decade later, the EDS was declared unserviceable and removed. The black border surrounding the black desto was once the distinguishing factor between this demonstrator and the production models. The 5-speed ZF 5HP590 automatic transmission is a unique feature in SBS9888Y as well.
SBS9888Y unfortunately met its fiery end along with 5 other double-deckers at Ang Mo Kio depot, destroyed by fire on the morning of 7 March 2010. Nobody was injured in the incident.
