(a) It appears that Chakki Bank (CHKB) has been renamed as Pathankot Cant (PTKC). The official IR site indianrail.gov.in shows the station codes ['View Codes'].

(c) We had a trip to Dalhousie in October, 2011 when we detrained/boarded trains at CHBK. It is a station heavily guarded by army personnel [International border with Pakistan is 25-30 km away]. We were told a very large ammunitions godown was nearby. In fact there is a U-turn towards PTK, and PTK is hardly 2-3 km away..
