The object circled in red is a mirror. It is used to angle sunlight into the long unlit tunnels of KSR. This relieves the PW workers to some extent, otherwise it would necessitate carrying lights into the narrow tunnels. ()

Natural way of lighting up the tunnels , is there a person always present who is in charge of adjusting the mirror as per the direction of sunlight out there ?
