 SCP-342 normally takes the form of a mass transit ticket for the closest form of mass transportation to its current location. When held by a sentient person for any length of time, it will eventually change form into a transit ticket for a form of transportation its holder desires to use. This transformation always takes place when not being directly or indirectly observed. Anyone who uses SCP-342 to board a vehicle is unable to exit said vehicle by any means. Once the vehicle ends its route and ceases movement, the user will disappear from this reality. Users report a mounting feeling of dread prior to boarding the vehicle and culminates in panic-inducing terror shortly before disappearance.
