Can just extend 860 to Punggol via Seletar …
Via, (continue original route to Khatib Mrt), Yishun Ave 2/1,
Seletar Airport, TPE, Punggol Way, Sumang Link, Sentul
Cres, Punggol Pl
Not sure if there really is that much demand between Punggol and
Yishun to warrant a dedicated service.
From TPE stop, you have 39 & 969
From Punggol road, you have 965
And if you want to do a jolly ride, then you have 85 to take you
direct.
Don't see potential for another service from Punggol to
Yishun.
Punggol to Tampines is the one that is needed for PGL residents
right now.
