From your description, I think you are previously working at
Alexandra Rd near Pasir Panjang Rd.
U can try 855 and transfer to 51, 93, 100 at Queensway.
Yes I tried that many times before, but it is the least
effective option.
1. 855 waiting time is 15 minutes.
2. 855 no seats by the time reach my bus stop
(2nd bus stop after bus interchange),
stand for one hour plus plus.
3. Upp Thomson Road can get bad jams, 100% jam at Thomson Plaza
area, and at Macritchie Viaduct.
4. Farrer Road to Queensway prone to jams.
5. 51, 93, 61 and 100 waiting time
is about 15 minutes. These services all bunch together.
When they come, they all come together, it is never a (15 divide by
4) mins wait.
So by this way I can leave home at 7:30am and
still be late for work at 9:30am and kena scolding from
boss.
