After observing Tampines Concourse Interchange, it further makes
sense to have new services start from Tampines Interchange,
especially those that won't ply near the MRT. My initial
understanding was that there would be an automated traveletor
between Tampines MRT and Concourse like the one at Serangoon
connecting NEL and CCL. But given the long walk, no one's going to
do it.
Tampines Concourse Interchange
Existing services: 18, 39, 129
Future services:
3 -> since it passes by Tampines MRT along ave 4
114 -> Tampines Concourse/Sengkang service via Ave 5, 4, 7
duplicating svc 27 to Sengkang (speculation)
3 cannot. Based on my observation, more people board 3 at
Tampines Int than Tampines MRT.
