BBDEP, and ARBP as well. ARBP was roped in to help with the
parking of all the JB Mk III's, including the SP's, after the
introduction of Svc 160. tis is because the number of JB Mk III's
required has gone up from 60 to 80, including the SP's for 160 (160
does not use all 20 additional buses).
Note that every JB Mk III, including SP's, has an assigned route
(160 or 170, each with their respective pool of SP's) with the
specific licence issued by the Malaysian authorities pasted inside
the bus. thus the SP's cannot be deployed anyhow on 160 or 170,
though they can be deployed on any other SBST services as
cameos.
