yea, you may be right. they might just be contructing another
platform, not a new track. but if this is the case, then 3 sets of
platform screen doors would be needed, not 2, but the platform
screen door website say only 2. i dont know, maybe there may be
changes.
however, if the southbound platform is to be block off from the
north bound by wall or something, then only 2 sets of platform
screen doors are needed. however, i would rather that the south
bound platform not be separated by an opague wall, but just by the
platform screen doors instead, so that, for any south bound train
can have doors open on both sides, so that south bound passengers
may use the north bound platform as well. south bound passengers
need not then worry about going down the wrong escalator. also the
station platform would look more spacious as well. i hope this
would be the case if they are not building any new track.
