LOL.. Hougang Central Int so new, upgrade for what.
Probably places to look at are Yishun Int, Tampines Int, Bukit
Batok Int...
Tampines Int had just been refurbished in 2008. I liked the way it
is now. It had memories of my childhood, even after it is
refurbished, as the berths for 18 and 39 remained unchanged...
Anyway, i doubt there is any space in Tampines Central for an
integrated hub...
