Route History

Premium 531 serves housing board estates, private estates and condominiums around Simei and Upper East Coast with connections to Suntec City, Marina Centre and Shenton Way, eliminating the hassle of transferring between different modes of transport. At the same time, SBS Transit’s Fast Forward 10e also offers peak hour connections between Upper East Coast and Shenton Way at a cheaper price (~$2.18 adult card fare as of 2015), but takes a longer journey by not plying along expressways.

Since its introduction in 2007, Premium 531 has experienced considerably high demand from the niche market, mostly from the private housing areas around Upper East Coast, where 531 is a the fastest bus route to the CBD despite its high fares. High capacity articulated buses were deployed on this service duing its initial days of service, when there were just 2 morning departures and buses were filled to the brim (despite the Premium no-standing regulation), and some buses (e.g. TIB1081S) were re-tuned for better climbing of Benjamin Sheares Bridge. Articulated buses were eventually removed when more weekday peak hour trips were added.

Originally operating with 2 morning and 2 evening trips, Premium 531 operated with 6 morning and 3 evening trips at its peak under SMRT, making it among the most successful Premium routes around. Most trips were fully seated.

Please note that this service does not call at 03059 Raffles Quay (One Raffles Quay).

    2 days in a row (yesterday and today) the last bus was a no show. I might as well voice my other concerns here: i noticed on 2 occassions the driver was using his cell phone while driving; and for 5.50, i expect the contractor to at least provide commuters with a decent bus, not one that squeaks throughout the journey. And on particular one day with heavy rain, it was leaking water via the aircon vent.
