this is the reply i got from LTA. There is no problem in
transferring between 170 and 170X at the checkpoint.
DISTANCE FARE FOR SV170/170X
FEEDBACK NUMBER:20100811-0031
We refer to your email dated 11 August 2010.
You may wish to know that
service 170X and 170 are considered the same service.
Hence, transfer between these two services is not valid
according to the transfer rules and the Fare
Calculator is unable to allow calculation of fares for
transfer between these 2 services.
However, at two
special stops, at Woodlands Checkpoint and Johor Bahru check
point, transfer between any of Service 170, 170X or
160 are allowed albeit not the normal transfer rules.
At these two points, SBS Transit Ltd has allowed transfer
between these services as if the passenger did not alight
from the bus. Unfortunately, due to technical
limitation, the fare calculator is not able to
effectively compute the same for transfer between
service 170 and 170X.
isn't strange or funny...
Checkpoint mode gotta be done by SBS yet the system i.e. online
calculator all done by LTA...
The reply I got (way nong ago) did not even mention abt CIQ
issue.
