The shallowest stn is Sengkang- need short esclator to get to
L1. I believe there's no more stns more shallow than this, stns are
getting deeper and deeper.
The shallowest SMRT stn is Newton, not Novena. -12m deep. Novena
is below malls.
What about Punggol? Like Sengkang, the concourse is also on the
surface level.
I read an article before, it mentioned Novena is the shallowest
on the NSEWL.
