Supplementary Service 131M served residential estates and schools around Bukit Purmei and Lower Delta Road with connections to Jalan Bukit Merah and Bukit Merah Town Centre. It duplicated its parent Service 131 along its entire route, and enhances connectivity for Bukit Purmei residents.

Introduced as a replacement for Feeder Service 275, this route duplicates the withdrawn Service 275 entirely. Both Service 131 and Service 275 were duplicating between Bukit Merah Int and Bukit Purmei Ave since the amendment of Service 131 in 2005. As such, Service 275 had low frequencies until the Bus Service Enhancement Programme (BSEP) in 2013. To better utilize resources, Service 275 was withdrawn entirely, and Service 131M introduced to take its place, operating only during weekday peak hours. Service 131M was later withdrawn in December 2022.

    How come waiting time so long:

    I suggest: 14 – 19 minutes if SBST agrees that 131M is a short service and needs a lot of time to reserve buses for service 131M

    Boring service, I want service 275 back!!!

      Amend service 131 and withdraw service 131M, then 275 ply it’s old route plus an extension to HarbourFront Int/MRT

        So pre-Sentosa 123 but massively shortened? You could always take 131 to Bt Purmei Ave and them wait for the next 123M
