Hi preservedorange,
For scenario 1, when you travel on the MRT/LRT, you must
complete your trip within the allowed time. The time limit is as
follows:
Exit 1-2 stations away = 20 mins
Exit 5-9 stations away = 40 mins
Exit 10-15 stations away = 75 mins
Exit 16-24 stations away = 100 mins
Exit over 24 stations away = 120 mins
If you exceeded the time limit, your ticket will be rejected.
You have to go to the Passenger Service Centre and pay an
administrative charge of $2 for your ticket to be upgraded.
For scenario 2, the minimum fare will be deducted when you tap
out. If you change your mind after you have tapped in, go to the
Passenger Service Centre. Your journey will be cancelled and the
staff will let you out.
oh i see, thanks for answering that niggling query for me!
