The one week training for route,equipment was from ComfortDelgo
spokesperson appeared in Dec 2 edition of TNP.
Based on historical territory segregation by transport authorities,
to minimise customer confusion on the sudden deployment of SBST
buses on SMRT routes, i do not think any SBST buses will run on
SMRT routes during this interim period.
The authorities already have a headache last week, they do not want
another incident where local commuters making noise and shock from
another fiasco.
SMRT OCC will know that their buses are deployed on time, kept to
schedule with their own buses on the road rather than that of
SBST.
I gather the redeployed SBST BCs are SG/PRs rather than from
PRC.
The PTOs have no say in this, transport authorities are the one
managing this, so do not think SBST is kind to lend BCs to
SMRT.
It is School Holiday schedule for most if not all services, so BCs
on scheduled OFF/LEAVE should still be able to go
can always paste SMRT logo like how Panorama Melaka pasted their
logo over rapidKL's
