OMG as I took the Taipei MRT system
1) off peak freq = 3 - 4 mins (SMRT 7 mins, MTR 4 mins)
2) single trip ticket uses token chip (slot into a empty
slot below the card tapping sensor as u exit the
station, instead of the usual tapping of the store value card).
Over here need to go queue at GTM again to return $1 
3) The sides has LED boards to indicate destination station
4) Front and rear indicates destination instead of the running
no here
5) Courtesy messages asking passengers to move in (in Chinese,
Hokkien, Hakka & English) aired at major stations/
interchanges
6) Passenger information system even indicates exactly how long
would the train be arriving - countdown timer
As I took the Taipei MRT, really ashamed, over here SMRT or
whoever thought of the ez-link system makes Singapore a laughing
stock. We're moving back to a 3rd world nation - more goods years
to come
