I don't know, but I have a funny feeling that, somehow, PTC is
biased against SBS Transit, so that stupid "2 own, 1 rival" rule
doesn't seem to apply to SMRT. Look at routes such as 853, 854,
855, 857, 966, 61, 67, etc... and so on. They clearly violate that
rule, and yet they are still allowed to run!
It's just my feeling, but...
