'''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.

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.

=== 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.
