Actually 6316B's loading abit inconsistent while doing 168, good
choice for it to take DD instead.
Overall, SD still alright but the bus(6316B) always spotted
showing "SBS Transit"(Off Svc) at times where it suppose to do
svc
Hope this DD won't
be like the Citaro
True, so you can't really rely cuitaros on high-demand
services...
