The SBS Express Services 501, 502, 503 & TIBS Express 520
were introduced on 5th May 1997 as part of the extension of the
Road Pricing Scheme and the introduction of more Park-And-Ride
carparks in areas such as Boon Lay Ave, Clementi, Hougang Central,
Eunos, Simei, Ang Mo Kio, Bukit Batok & Yew Tee.
THE HISTORY OF SBS TRANSIT EXPRESS SERVICES
Express Services was non-existent before 1994. That was when SBS
introduced Express 16E, which is a short route of service 16
between Bukit Merah & Changi Airport. Unlike other 'E' code
service (which is currently used for Fast Forward Services in SBS
Transit), it operated daily at 6 - 9am and 5 - 8pm.
16E - Bukit Merah - Changi Airport
Same route as service 16 (at that time), but skips all the bus
stops from Nicoll Highway to Airport Boulevard. To Bukit Merah, it
skips the bus stops from Marine Parade Road to Stamford Road.
However, just 3 years later in 1997, it was renumbered 36 and
converted to trunk service, although the timing is still the
same. In 1998, due to duplicating 16, it was converted
into a trunk service and routings are totally changed. Timings are
also adjusted too.
In mid-1997, three Express services is introduced by SBS. They
are:
501 - Hougang Central - Outram Road/Shenton Way
502 - Hougang Central - Boon Lay
503 - Tampines - Orchard/Suntec City
Service 501 & 502's routing look somehow similar, via Upp
Serangoon Rd, Hougang Ave 8,Yio Chu Kang Rd, Boundary Rd, Ang Mo
Kio Ave 1 & CTE.
After CTE, 501 go down to Outram then to Shenton Way and go back
to Hougang Central via Rochor Road (express). 502, however, going
to its original route to Boon Lay from Orchard.
503's routing is just typical using the current 518's route.
In 1998, three more services is introduced by SBS. They are:
506 - Bedok - Jurong East
507 - Boon Lay - Shenton Way
508 - Sengkang - Shenton Way
506's routing was using its old routing from Jurong East - Bedok
North Ave 3, plying Bedok North St 1 and the interchange. 507's
route is availble on the website http://www.sbstransit.com.sg/press/2004aug_16-1.aspx.
508's route, however was duplicating part of current 501's route
until Hougang Ave 8. It plies Hougang Ave 4, Yio Chu Kang Rd, Ang
Mo Kio Ave 3 & CTE. It also used 501's route to Shenton Way
& Outram Road except Marina Centre.
However, SBS enhanced two express services to serve passengers
better:
501 - To ply Marina Centre after Fullerton Rd via Temasek Blvd
& Ave and Raffles Ave, Stamford Rd & Penang Rd before
continuing its route to Hougang Ctrl via CTE. It's also converted
to loop service.
501X - Alternative to 501 except that it did not ply Outram Rd
& Shenton Way.
503 - Renumbered 505 and extended to Telok Blangah area, skipping
Marina Ctr portion. It's also extended to Pasir Ris and converted

In 2002, Express 506 was shortened back to Bedok
Interchange.
In 2003, during the NEL Rationaliasation, 501, 511 & 512 was
withdrawn and 502 was shortened to loop at Marina Ctr.
In 2004, due to poor demand, Express 507 was withdrawn.
In 2005, Express 502 & 518 was enhanced:
Service 502 was extended to ply Pioneer Rd North, Jurong West
Ave 5, St 75 & 64. It no longer plies Commonwealth Ave West,
Clementi Ave 2, Holland Rd & Tanglin Rd. Service 502A &
502B were introduced to complement Service 502.
Service 518 was enhanced to cover more of Pasir Ris Dr 3, 12
