Records

The first stations in the world with platform screen doorways were the ten stations of the saint peters burg metro’s line 2 that opened among 1961 and 1972. the platform “doors” are virtually openings within the station wall, which helps the ceiling of the platform. the music tunnels adjacent the ten stations’ island platforms had been constructed with tunnel boring machines (tbs), and the island structures were honestly placed in a separate vault among the 2 song tunnels. commonly, tbs bore the deep-degree tunnels among stations, even as the station vaults are dug out manually and include both the tracks and the platform. but, within the case of the saint peters burg metro, the tbs bored a couple of continuous tunnels that passed through ten stations, and the stations themselves were constructed in vaults that handiest contained the platform, with small openings on the perimeters of the vault, in order for passengers to get right of entry to the trains in the tunnels.

In 1987, the Singapore met become the primary metro device inside the world to contain glass pads into its stations for climate manipulate and safety reasons, as opposed to because of architectural constraints.[1] all underground stations on all strains have those doors mounted on account that their establishing, and above-ground stations had been retrofitted with the doors through 2011. the layout of the doors themselves fluctuate relying on their installation location and time (see underneath).

After cleansing up and sanding the face and again of the door he’ll suit the election molding and cover molding in the general way by way of screwing thru slotted holes in the panels into the collection mounding and then protecting the screw heads with the internal cover moulding that’s pinned to the body of the door and now not the panel.
