I am not sure if you understand my concerns. Anyway just to
reiterate, for making bus/train transfer for MRT stations along E-W
line, one probably need to walk not more than 5min from Platform
(not control station) to the nearest pair of bus stop. However
that's not true for some Circle Line Stations, example Marymount
and Holland V, one probably need to walk for 10min from Platform to
bus stop. The ease in making bus/train transfer will definitely
encourage more to switch to public transport.
