In my opinion, SMRT bit off more than it could chew. The
transfer of "territories" was one of the big mistakes. SBST gave up
15 services in exchange for just 8. And SMRT just didn't know how
to utilise potential money-making services. Services 61, 67 and 190
were doing better when they were controlled by SBST.
Also, it's my dream to see Bukit Batok reverting to SBST control. I
don't know why, but SMRTB can keep Choa Chu Kang and Bukit
Panjang.
