    Service 138 should be deployed MAN A22s to inform passengers (tourists specifically) when the Singapore Zoological Bus Stop has been reached and also to remind elderly locals from Singapore and possibly Malaysia that the have reached the Bus Stop closest to Bandai Crematorium and Columbarium

      Hi Regan,
      MAN A22s are not the only ones with speakers, the Citaros have too! So deploying A22s on this route is redundant. Furthermore, Citaros have a more luxurious look than A22s. Furthermore, a A22 once cameoed on the route, if you never catch it then…
      Cheers,
      SG5835M

        The A22 cameo was once a 927 perm that went over to AMDEP to serve YIS route group.
