The following information about Service 640 were submitted by a contributor previously:
Bus number plates and departure timings:
| Morning (AM) | |
| Bus plate number “PA2226H” | Around 7.10am to 7.15am @ Block 508 Carpark, Canberra Road (trip no longer in operation as of 2024) |
| Bus plate number “PC9133K” | Around 7.15am to 7.20am @ Block 508 Carpark, Canberra Road |
| Bus plate number “PC6222G” or “PA6011J” | Around 8.05am @ Block 508 Carpark, Canberra Road (trip no longer in operation as of 2024) |
| It is unclear if the bus driver starts to pick up passengers before this bus stop or at the nearby Koufu.
At any day, any of these 3 buses will ply the weekday morning route at the above timings so look out for the bus plate number, unless there are sudden changes and passengers will not be able to get hold of the information beforehand. |

| Evening (PM) | |
| Bus plate number “PA2226H” or “PC9133K” or “PC6222G” | Around 5.25 pm @ Hub Synergy Pt, Anson Road |
| Buss plate number “PA6011J” | Around 6.05pm @ Hub Synergy Pt, Anson Road (trip no longer in operation as of 2024) |
| Passengers are advised to start their journey from the bus stop at International Plaza outside Tanjong Pagar Station instead as that is the confirmed bus stop the buses will start their PM route.
Similar to the morning route, at any day any of these 2 buses will ply the weekday evening route at the above timings so look out for the bus plate number, unless there are sudden changes and passengers will not be able to get hold of the information beforehand. |

Advice for new passengers wanting to try this service:
- As the drivers are known to spot regular passengers at bus stops and along roadsides (yes, the drivers may stop suddenly along the roads to pick up regular passengers not at the bus stop), therefore it is best that you can become their regular passenger for this service
- New passengers must press the bell as early as possible if you wish to alight as drivers do not stop at every bus stop, and sometimes they accelerate along certain stretches despite having bus stops with their service. As per point 1, drivers recognize regular passengers and can pinpoint exactly who will board the bus at what time and alight at which bus stop. Do not be surprised if the bus suddenly stops halfway without bus stop and passengers alight.

Yes, only PC9133K is in operation. Based on the bus driver uncle, ridership has dropped sharply over the years as regular customers no longer take the service due to change of jobs or WFH, and also due to the opening of TEL from Springleaf all the way to Shunfu, which used to have no direct train service but only bus services. Therefore, the rest of the drivers no longer run this route anymore.
