Hello,
Singapore's bus services and Malaysia's bus services are very
different. One aspect is the integration of the different bus
companies. Here in Singapore, SBST, TIBS and SMRT are all
integrated to form a seamless transportation network which is one
of the most efficient in the world. In Malaysia, there are many
small bus companies which is not that integrated. However the
Malaysian authorities is now integrating all the public transport
operators. One example is the government's purchase of DRB Hicom's
IntraKota and STAR-LRT/ Putra-LRT.
The magnetic farecard system known as Transitlink in Singapore, is
not exclusive to Singapore, therefore the system can be seen on
Malaysian buses. Malaysian bus operators does not operate any
double-deckers, not sure if any of them are planning to.
Cheers and warm regards
