These operational changes implemented by SBST are the result of a new Framework Agreement (or “FA”) announced by SBST and LTA in November 2021, in connection with the transition of the Downtown Line to the New Rail Financing Framework Version 2.
SBST had agreed to replace 241 of its own buses (comprising 144 double-decker buses and 97-single-deck buses) with newer government-owned buses, which are more environmentally friendly and cost-efficient to maintain.
