Good. Now bring in more of these from non-WAB routes, and make
them perm on this one. And when the production Citaros come in,
make them perm on it too. And make the buses more frequent. Then
make it a WAB route.
Otherwise they will never live it up to SBS Transit's Scania
K230UBs at Changi Airport, and you will have people bitching about
long waits for this route's buses.
I actually do not like WAB on 858. Not sure if anyone shares the
same sentiments but putting a OC on 858 means the more pax from
changi have to stand for at least 35 mins. And in addition, they
are limited to 60kph where compared to o405's 65 to 70kph, which
might be another reason why the wait gets even longer.
