Express Service 518 connects the residential estates of Pasir Ris and Tampines to the City areas of Moulmein, Orchard Road, Marina Centre and Bayfront. It incorporates a express sector from Bedok North Road to Moulmein Road via PIE and CTE, and another express sector via ECP, KPE and PIE from Bayfront back to Bedok. The route is popular among residents in Pasir Ris and Tampines as a fast bus connection between home and City, and double-deck buses were introduced to the fleet in 2014.

In 1997, the route numbered Express 503 was introduced by SBS as a unidirectional peak-hour Express service between Tampines Int and Temasek Ave/Anson Rd, operating City-bound trips in the morning and return trips in the evening. It was later renumbered Express 505 in 1999, converted to a full day service and extended at both ends to start from Pasir Ris Int and loop at Telok Blangah Rd. Finally, it was renumbered to Express 518 in 2000 and shortened to loop at Marina Centre. The route has not seen any major amendments since, except for the 2012 amendment which extended it to loop at Bayfront.

A peak hour variant, Express 518A, operates during Weekday Morning Peak Hours with two departures from Pasir Ris Int which terminates at Bayfront. These trips skip the Tampines and Bedok North sectors of the route, allowing for faster commute from Pasir Ris to the City.

Amendment to KPE

Service 518 was planned to be amended to ply the Kallang-Paya Lebar Expressway (KPE) and Pan-Island Expressway (PIE) between Bayfront and Bedok North on the first day of Go-Ahead operations (18 Sep 2016), reportedly specified in official route information such as the TransitLink E-Guide website. However, Go-Ahead service guide lists the old express routing via Bedok North, and buses have been following the old routing in the early days of Go-Ahead operations. Go-Ahead formally began using the amended route via KPE on Friday, 23 September 2016.

    Saw SG 1720L on service 518

    I suggest:
    Add in “MAN A95 (3-door)” in the current fleet list

    I was at Tampines East Station Exit B waiting for bus 518 at 245pm. The bus drove straight through the bus stop without even realising I was flagging frantically at it. This is not the first time I encounter this and it really drives me crazy because getting onto the next bus will make me late for my appointment. I hope the organisation can take a look into this matter.
