151 and 154 are amongst the crappiest services I've seen. They
are always competing to see who can drive the slowest and the loser
will be forced to take the student crowds.
On one fine day I still remember along PIE towards KRT, my 151
was forced to overtake the 154 who was going at bicyle speed.
My bus overtook
that fella at a cool 30KM/H
And guess who overtook my overloaded bus at King Albert
Park?
151's riding experience leaves much to be desired. Erratic
waiting time (anything from 10 seconds to 25 min at Terminal),
erratic travel time (anything from 50 min to 1 hr 30 min off-peak
depending on BC's mood), erratic scheduling (if any) and worse of
all, there are BCs which I won't reveal, to be avoided at all cost
(slow and
dangerous driving). Not to mention this route seems to have
a very high turn-over rate. I've already had 2 chances of watching
newbies being guided throughout the journey (and nearly miss
Stevens Rd exit).
In short, if you need some stress, 151 is the service for
you.
