'''Platform Screen Doors''' (abbreviated as PSDs) are used at many rail stations in the WolvHaven server that ~~seperat~~ 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.

'''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.

Prior to the creation of piston-based PSDs, the tracks were instead seperated from the platform by a wall of glass, with openings in the walls to allow passengers to board or alight.

Line 17:

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

As a result, the layout would consist of 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

Small profile doors do not have the abilitiy for individual door control, as the leafs of two different doors were shared by a single redstone column.

=== Mk IIIA Flip-Flop Train-Depart (2013) ===

Flip-~~Flip~~ train-depart uses a signal that is triggered by a detector rail when the train departs to close the doors by activating the flip flop. Despite its benefits of a smaller footprint, these were plagued with reliability issues; often having an opposite operation problem where the doors closed when the train was in the station; and opened when it was not. This frequent issue prompted the introduction of a "PSD Reset Button" that was often located in the middle of the platform to reset the doors if it was in opposite operation. A fine for misuse of WH$300 was imposed for misuse of the reset button.

=== CB1 Command-Block Based (2018) ===

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.
