i can merely recall that when i was young, the air conditioning in
MTR covered every places of a station namely, lobby, passages, platform, 
of course, coaches, ....

later, a notice saying "An conditioning maintenance and repair is in 
progress, sorry for the warmer condition caused. We regret for any  
convenience.." (something like that). From that on, all the places 
excluding the train coaches were no longer "air-conditioned"

now, the situation doesn't get improved but the notice mentioned above 
was taken away for a long time.......

is my observatino true?
if yes, why does MTR remove the air-condition gradually and in the 
absence of publicity?

pls comment and answer these question as i have been in doubt of them 
for a few years! :)
