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 (~$2.21 adult card fare), 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 Shears 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 now operates with 6 morning and 3 evening trips, making it among the most successful Premium routes around. Most trips today are still fully seated.

This service does not call at 03059 Raffles Quay (One Raffles Quay).

Operating Days:

Operates during weekday peak hours only. Does not operate on Saturdays, Sundays and Public Holidays. During selected eves of Public Holidays, evening departures may be brought forward to the afternoon.

Fare: Flat fare of $5.50. Transfer rebates & concessionary travel are not applicable.

Fleet: Premium 531 commonly operates on MAN NL323F buses, under crossover slots from other services (like 167 or RWS8). Other buses like Mercedes-Benz Citaros make an occasional appearance. Bendy buses were discontinued after the number of trips were increased, but do make their appearance very rarely.
