Yes, now along side the PA-registered Dennis Lances, buses from
the main SMRT fleets (mainly Hispano O.405s) and a couple of CSS
buses used for the Pasir Ris - SFT shuttle.
The buses used are not exactly spares.
For the shuttles during P Tekong book in/out periods, different
depots will take turns to deploy buses, e.g.
FRI: KJDEP
SAT: AMDEP
SUN: WLDEP
The above was based on timings during my BMT days.
