    Service 125 should ply Moulmein Rd, Thomson Rd, Keng Lee Rd/Kampong Java Rd, Bukit Timah Rd (Little India Stn) in both directions. Should ply whole stretch of Serangoon Road towards Sims Drive and Bendemeer Rd (no change) and Jln Besar towards St. Michael’s Ter, skips Kitchener Rd. This amended sectors can help affected Service 66 passengers in the Little India/Farrer Park/Geylang area instead.
