Seriously, every trains terminates @ YCK and Lakeside.
Why? Boon Lay was only open 1990 and before that, the last phase
completed is Clementi - Lakeside.
YCK side is self explanatory where it is the first phase
terminus.
But I will prefer to see Boon Lay.
that one i know.. trains did terminates at Lakeside last
time.. now rare to see trains terminates at lakeside
