DA-099 is to be contained at Site-██ in a secure train depot. The entrance to DA-099’s containment chamber must be locked and guarded at all times. Only Level 3 personnel are permitted to enter DA-99’s containment chamber, and they must do so only with the approval of at least two Level 4 personnel. Any unauthorized personnel attempting to enter DA-099’s containment chamber are to be terminated immediately.
Description:
DA-099 is a train consisting of a typical Russian (specifically Moscow) metro train. DA-099’s exterior is composed of rusted metal and corroded glass, and its interior is sparsely furnished with wooden benches and dim lighting. DA-099 is fully functional, and its passenger carriages equipped with a functioning PA system.
DA-099 will appear at a random train station at least once a week, at which point it will remain stationary for approximately one hour before departing. DA-099’s destination is unknown, as it does not appear on any known maps, and DA-099 never returns to the station from which it departed.
Those who board DA-099 are unable to disembark until it reaches its final destination, which varies from trip to trip. During the journey, the PA system will play a recording of an unknown individual speaking in a language that has not been identified. The recording is reported to induce a sense of unease and fear in those who hear it, and some passengers have reported experiencing vivid and unsettling hallucinations while on board DA-099.
Upon arriving at its final destination, DA-099 will remain stationary for a period of approximately 30 minutes before departing again, leaving any passengers who boarded it behind. DA-099 will then disappear, and its current location is unknown until it appears at a train station again.
Addendum:
On ██/██/20██, a group of E-Class personnel were instructed to board DA-099 in order to determine its final destination. The D-Class personnel were equipped with GPS trackers, but their signals were lost once DA-099 departed the station. They have not been seen or heard from since. All attempts to locate the missing E-Class personnel or DA-099’s final destination have been unsuccessful. It is unknown whether DA-099 has the ability to transport individuals to other dimensions or alternate realities.
