Service 137 was withdrawn in late 1992. As such service 163 was
amended to terminate at Toa Payoh, covering the lost links between
Toa Payoh and Upp Thomson, and also to reduce duplication with
other services along Thomson Road to Marina Centre as part of the
rationalisation.
Anyway, it was a suggestion to extend it to Marina Centre via
Novena, Orchard, River Valley, Chinatown, Shenton Way and MBS.
Marina Bay was different from what it was in 1992. Now there is
MBS, so it will be good if there are links to there from Thomson,
Toa Payoh, Novena and Chinatown. Terminates the same place but
maybe a different route for different demand patterns. 137 can
probably bypass the zoo and use BKE to Jurong East, another fast
link from Toa Payoh to Mandai to Jurong East.
