Sourabh sir, the railway track on pf#2 for PQS is not connected with PQS-SGBA section. Pf#1 & Pf#2 of PQS are connected with only SDAH South Section, where, Pf#3 & Pf#4 are connected with SGBA, not SDAH. All suburban trains which bypass SDAH to reach BNXR, DDJ etc from PQS are arrived on pf#3 & pf#4 of PQS.
So, please, edit the pf no for PQS. Its pf#4 not, pf#2.
