That was what i thought last time when i didnt know about the
reserve names for future stations. last time it skip from N12
Yishun to N14 Sembawang, and i thought maybe 13 is unlucky no. that
why they skip. but i couldnt think of why they left N19 out.
i also thought that it is because of the long distance btw the
stations, but then i couldnt think of reason why Yio Chu Kang and
Khatib are so far but no skip numbers.(anyways this is wrong
reasoning in the 1st place because since they purposely reserve
name for future station to be in between, of course it follows that
the distance between the present 2 stations(Kranji and Yew Tee,
Yishun and Sembawang) is likely to be further apart.)
