If stage 1 are DT1 to DT6, what would be the station number after
Chinatown on stage 3?
According to below, stage 1 stations are numbered DT13 to
DT18 (while DT1 to DT12 are on stage 2), but they may have changed
it already.

How would I know? lol. i know about this diagram, it was in a
prev thread. all this not confirm what. im just showing what the
map at LTA website shows.
if Chinatown is going to be DT1, there could be 2
possibilities
1. after Bugis continue the numbering for stage 2. for stage 3,
the DT numbering continue from Chinatown. means not one continuous
stretch
2. renumber everything after stage 3 open if they want the
numbering to be one continuous stretch. but what for? might as well
dont number chinatown as DT1 in the first place.
another possibility: dont give the name "DT" for stage
3, the eastern region stretch. give some other letter.
