3-town rule only mainly applies to 39,85,161,168,965,966 and
969. But since most of them are diverted to serve the TPE stop
(sengkang/punggol) and 966 serves Jln Toa Payoh, think they don't
really care le

The "3-town rule" is also brought forward by LTA's BSEP and thus

All of these routes are planned by LTA (after 1995) and prior to
the LTA in 1995, the Minister dictates bus services and bus
fares.
103 was only extended to Yishun after the barriers were opened
up with Yishun Avenue 8 and Seletar Aerospace Park development.
