In some countries, such as
Queensland in Australia, the seats in their train carriages are
arranged similar to how the seats in the buses are arranged – seats
positioned perpendicular to the wall, instead of parallel to
it.
No doubt, this arrangement increases the seating capacity and
more passengers can get a seat but I am not sure if this is indeed
better for us, if our MRT seats are arranged
perpendicularly. 
What do you think?
