    Aljunied Road goes through Joo Chiat, never look on Google Maps ah?

      Erm I think you’re mistaken? Aljunied road does not pass through Joo Chiat.
      Anyways, some buses plying Aljunied road have double deckers e.g. 62 & 64. Hence the user’s question on why there are no double deckers on 100.

        MRT (EWL) is faster than bus. That is the reason why bus 100 does not need double deck, there is short-working trip 100A from Serangoon to Aljunied, serving Bidadari residents and there are no direct MRT links from Serangoon to Aljunied.

        Previously, on 5 November 1989, service 20 (Bedok – Ghim Moh) will definitely lose ridership when the MRT is ready and no one will spend long journeys on the bus. But there is a lot of trade-offs being involved as the section from Crawford to Commonwealth (excluding City Hall, Raffles Place and Tanjong Pagar) on the service 20 that it is in, do not have any MRT stations. The Fidelio Street and Frankel Avenue will get a feeder bus service 42, whereas service 100 can be amended and extended to skip roads with low ridership such as North Bridge Road (Lavender and Bugis).

        Even service 13 has duplicated service 111 to the extent from Ghim Moh to Orchard Road, service 7 was amended to skip Suntec City and instead ply Bugis area, ever since the MRT is fast for long journeys from Bedok to Orchard Road area while complementing it for people who are staying further away from the MRT station. That explains the reason why there is no bus service from Suntec to Kembangan area by now? And also 13 had went to Bishan and Yio Chu Kang to replace 58 and 133.

        Even 135’s constraint is just relying on private estate – Frankel alone.

        155’s height restriction is Telok Kurau only as it passes smaller roads.

    Why are there no double-decker buses deployed on this service? I realise that buses starting from serangoon interchange see poor deployment of double-decker buses (even services 109, 103 which see considerable demand only have few double-decker buses plying the route daily)

        but this service doesn’t pass through Joo Chiat. Isn’t that 155?
