Sembawang overnight parking cannot be Sedep as Seletar also
using Sedep which should have been Ssdep instead.
Might be a bit off topic..
But I don't think there's a need to even add the short forms like
WRDEP, YIDEP, CCDEP, SEDEP, etc.. That makes things even
complicated as those interchanges aren't really depots..
What's more AMDEP didn't give any short form for buses that
overnight at WRI, instead they reflect it as Old Wdl Reg Int..
