Going by one such circular sent by the zonal security headquarters to the divisions (copy available with DT Next) on April 28, trains could be operated in end-to-end basis covering major stations. The zones have asked the divisional security commissioners to consult their respective Divisional Railway Managers (DRM) and identify list of stations from where trains could be started and terminated and the number of unauthorized entry/exit points for closure at such stations. The security commissioners have also been instructed to instal CCTV cameras at entry and exit points. RailTel has been asked to take the assistance of GRP, commercial and S&T officials, if required, to install the cameras in a week.
