I went there again, and yes I saw it wrongly. Those are supporting structural walls, not pillars.

This may suggest `tunnel=yes` but consider these tracks are actually at ground level (observe from Shek Kok Road), and one may see sunlight while riding TKL at this location. Doesn't make full sense to get `tunnel=yes` (eg contrast Yau Tong Station where sunlight does not exist).

Might we do `covered=yes`?
