Item #: 4789

Object Class: Safe Euclid

Special Containment Procedures: SCP-4789 is to be contained in a standard large size, Low Security storage unit at Storage Site-42. The storage unit is to be guarded by one (1) armed low security guard at all times while not in use. Person(s) wishing to use conduct testing with SCP-4789 that are of Level 1 access or above are to submit a request form to Project lead, Dr.[REDACTED]. SCP-4789 is not authorized for use of "Sightseeing" by Foundation staff. Due to recent shifts in activity of SCP-4789 during active phases (See Test log #40) SCP-4789 has been reclassified as Euclid, And its Special Containment Procedures have been updated as follows. SCP-4789 is to be contained in a 100ft x 100ft steel reinforced concrete room, located in High Security Storage Site-[REDACTED]. It is to be under constant watch from personnel by way of CCTV cameras installed within the containment area, these are to be checked after every active phase for damage and repaired accordingly. No less than two (2) QRT's (Quick Response Team) under the command of MTF-Theta 9 (Station Hoppers) are to be on standby at all times for the event that SCP-4789 enters an active phase. Should any instances of SCP-4789-1 materialize during this time both QTR's are to be sent into the containment area in no less than standard MOPP-4 Hazardous Environment gear and terminate all instances of SCP-4789-1, the remainder of MTF-Theta 9 will be put on high alert at this time and be ready deployment if needed. Should any living living or dead (see Incident Report #[REDACTED]) Human enter SCP-4789 during this time Protocol Apollyon-101 is to be enacted by any surviving members, at this time [DATA EXPUNGED BY ORDER OF 05 COUNCIL, IF YOU ARE OF SECURITY CLEARANCE LEVEL 4-4789 OR ABOVE AND WOULD LIKE TO VIEW THIS DATA PLEASE SEND IN A FORMAL REQUEST FORM.] Should this fail, the On-Site nuclear warhead is to be detonated remotely once any surviving staff reach minimum safe distance.

Description: SCP-4789 is a standard R44 subway car built in 1971 by St. Louis Car Company, it was in use in the NYC Subway System from 1972 until 2007 when it was decommissioned by Staten Island Railway. It's anomalous effect was discovered when deep cover agents within the NYPD were alerted to a call from the owner of a junk-yard who triggered an active phase by entering SCP-4789 to inspect it. Foundation assets responded and secured SCP-4789, the junkyard owner was interviewed (see interview log #1) and administered class-A amnestics. SCP-4789's anomalous effects manifest themselves when it is entered by any human, causing it to enter into an active state. SCP-4789 has begun entering its active state without human interaction (See Test log #41). Once in an active state, the doors will close behind the subject inside, subjects commonly report feeling as though to car is moving, though no movement is detected from the outside. After approximately thirty (30) seconds the windows will darken for a variable amount of time, as though the train was moving through a dark tunnel. Once the windows begin to lighten again subjects report being moving through various locations as part of a larger train, after about ten (10) minutes the windows will fade to black and the process will repeat three (3) more times, at which point the doors will open and SCP-4789 will enter its inactive state. The most common locations reported by subjects are New York City, London, Seoul, and [REDACTED]. Any persons outside of SCP-4789 during its active state will report it being completely inert, with the exception of not being able to see through the windows. While in its active state, none of the doors within SCP-4789 will open by any means, and any effort by subjects inside of SCP-4789 to contact beings in any other car is considered futile Subjects are not to try and contact beings in other cars unless instructed during testing (See test log #40).
