'''Platform Screen Doors''' (abbreviated as PSDs) are used at many rail stations in the WolvHaven server that seperate the platform from the train tracks. WolvHaven was the first minecraft server/project in the world to incorportate piston-based platform screen doors that slid horizontally in its railway systems; which were invented in early 2012.

The earliest form of the PSD would consist of only 3 doors to accomodate the server's then 10-minecart trains. As they were retrofitted into stations that previously had platform glass walls, the redstone for the PSDs had to be compact.

As a result, the layout would consist of a two single-leaf doors; one on each end, with a single double-leaf door in the middle; similar to that of a deep-level london underground tube stock with single-leaf doors on the ends of the train cars

Command block based PSDs are also present where command blocks replace the doors with air and back with the doors again. This was introduced by [[User:Starcubed|Starcubed]] and the doors are implemented on at Stadium and Waterloo stations of the [[WolvHaven Metro (4th Haven)]]. The footprint of such doors is large as schematics of the doors being closed and open had to be stored above/under the platform for the command blocks to copy them from.
