This makes it impossible to have platform screen doors at a particular distance. Then the doors of all trains will not be aligned to the screen doors,” a Metro official said on Tuesday. Calcutta Metro had earlier sent at least two proposals to the Railway Board to install platform screen doors but those were turned down because of the technical problems. A Metro official said that steel barriers had once been placed on a platform along the tracks to find out whether it was feasible to install platform screen doors. Another official said that with proper planning and funds, the entire system could be overhauled and platform screen doors installed.
