Those buses probably won't come with the SBST base livery.
Most probably most of them have not arrived yet, those SG50XX
and 51XX buses are mostly from the 415 buses. Then the 176 buses
will be to replace the SBST buses transferred to the GCM.
Didn't you read the statement? It clearly say that 30 buses were
delivered in 2015.
So what livery these buses are in?further in 2015 have LTA
decided on the green colour theme?
Even the 415 buses order was placed earlier, the scheduled
delivery were up to 2017. Volvo is capable of producing more buses
at the same time. So delivery of the 415 buses go along with
the delivery of the 176 buses. Just that some of these 176 buses
were in SBST livery since they need to be deployed earlier b
