Platform Screen Doors

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.

History

Despite the creation of Platform Screen Doors to make the system more realistic; similar to the Singapore Mass Rapid Transit system and stations on the London Underground Jubilee Line Extensions, the doors were there to prevent players from getting onto the tracks into the paths of oncoming trains, which would disrupt service as the server was not familiar with traincarts properties at the time. It would also help to prevent trespass, and ensure that the automatically operated lines remained in service more often.

Since 2014, with the implementation of player-collision train properties on traincarts systems in the server, the WolvHaven has introduced rail lines that would not include the technology as it was no longer essential to have the doors installed at all stations.

Door Types

Small Profile

Earlier PSD models in the WolvHaven server utilised the small profile doors. The right leaf of a door and left leaf of another would be controlled by a singular redstone column. The small profile doors would fit in the server's rail infrastructure; which was of smaller scale at the time.

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

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.
