The buses of the following services have this system (using a
grey console):
24 (All) , 88 (All), 238 (All 8, excluding cross-over buses), bram
SPs(0099S, 0127U, 0169Z, 0173K), amdep VLS trial buses ( 322Y (now
on 105), 364B) and some 55 and 133 bus
The buses of the following services have this system (using a black
(System by Orbital) console):
54 (All) and SBS 145S of Service 28
I do not really know whats the use of those console but I do know
buses need not have the console to operate their VLS systems, I've
took buses of Sv 153 and 966 in which the drivers need not touch
the IDFC (The blue fare console we see on all revenue service
buses) and their fare stage changes by it self, I can tell you that
for Service 966 (towards Woodlands), it changes to stage 35.0 right
after entering PIE by the Whitley road (CJC) enterance without the
driver pressing the IDFC, the system that transmits the infomattion
for farechanging should be somewhere at the back of the drivers
seat and is transmitted via the antenna of the bus to the stallite
in space back to the bus
