yeh pf-1 and pf2 ke beech ka track hain naa.Bhai kaam to teji se chal raha.Abhi block tha kal taaki pul bogda ka part pura kar sake.Bogda pul ke aage ka part lagbhag khhatam ho gaya hain.Even extended loop bhi HBJ tak pahuchne wala hai.Bus subash nagar bridge ka kaam bacha hai.So you can expect till feb 2018 or march
