IMO , svcs like 105 181 240 242 243 335 502 ,can be WAB svcs
long ago
242 dunno waiting for what for so long .. -.-
Most probably due to bus-stop conditions along the Jurong West
areas.
Also add on to more bus services like 18, 19, 24, 26, 39, 45,
48, 55, 56, 59, 60, 66, 73, 86, 88, 90, 94, 100, 109, 124, 125,
128, 133, 135, 136, 154, 155, 157, 163, 186, 238, 241, 292, 506
which have plenty of Scania K230UBs in its fleet but not WAB
yet.
Service 100 was in fact the 1st service to get Scania K230UB in
2007 but it is still not a WAB yet, likely due to the boarding
point at Serangoon interchange.
