Last time during the SBS era, the arrangement of Bukit Batok
Interchange are as follows:
Berth A
61, 106, 189, 77 and 852
Berth B aka Sawtooth Berth
173, 177, 361, 365, 367
But due to 61, 106 and 189 using bendies and there are not enough
spaces for them to park at berth A, they swap with 173, 941 and 947
which does not use bendies, that makes only 945, 173, 177 and 852
without any shift in parking areas
