It's been there since long.Yes it was not there before but may be when they developed the Eastern Entrance a while back,the F.O.B was developed along with it.They are building up one more,connecting Platform 1 with 2&3 when the R.P.F station between platform 2 & 3 was demolished.The foundation is done with and they are pulling up the pillars.Would try to post the pic,say by tomorrow. :)
