Unfortunately don't think there will be any demand to
MBFC/Shenton Way during off-peak hours.
513 and other BSEP express services operated by SBST/SMRT (850E,
982E, 951E) were probably LTA's early experiments of City Direct
services. LTA then realised it's unsustainable to let SBST/SMRT
operate them, hence they gave other planned services to private
operators.
Hi mr array88, I don't think it is unsustainable. They just want
to let others have a piece of the cake. Cheers. Thanks.
