Fig. A The F train at the beginning stages of SCP-X.
Item #: SCP-X
Object Class: Neutralized
Special Containment Procedures: Under the auspices of subway reform, the Foundation (in collaboration with the New York City Metropolitan Transportation Authority) has installed Type-IV Paracoustic Totems across the F train route. Detected phenomenon is to be archived and investigated.
Description: SCP-X was an anomalous event that occurred on 2017-09-08 on the Coney Island/Stillwell Avenue bound F Train. Between the hours of 8:11 PM and 10:45 PM, the passengers on board experienced severe misfire in their sensory stimuli — most were unable to precisely identify objects or locations where sound had originated from. Audiovisual devices were affected in a similar manner and always in correlation with what their operators saw or heard.
As evidenced by footage, photographs, and timestamps, a teenage female (hereby designated SCP-X-Odessa) had appeared on multiple train compartments, often times simultaneously. No recordings exhibit SCP-X-Odessa physically moving from one compartment to the next. All depictions of SCP-X-Odessa had injuries (from lacerations or cigarette burns) on its person, which were barely covered by a long-sleeve sweater.
Below is a timeline compiled from confiscated recording devices.
Addendum-X: Timeline
Fig. B F train captured by Witness-1's phone.
8:11 PM|Jay St - MetroTech Station: Witness-1 captures footage of the F train as it enters the station. A loud jingle is heard — this is followed by an announcer greeting passengers and reading out subway destinations. The doors open and the camera operator moves into the first compartment and sits next to SCP-X-Odessa who wears headphones, which emit the lyrics "sing me to sleep"1 due to high-volume.
8:12 PM|Bergen St Station: Witness-1's phone footage shifts periodically from the floor to face the operator who monologues on their retail job. The view shows passengers attempting to maneuver into the highly populated compartment. The view depicts SCP-X-Odessa as it rocks uneasily, and raises its knees to its chest.
8:13 PM|Carroll St Station: Witness-2 enters the third compartment. A child's cries are heard from their right earplug. The camera from their phone turns on and records a distressed mother (sat ~4.5m away and left from Witness-2) who dips their head close to the stroller several times in confusion. The child's cries increase.
8:15 PM|Smith - 9 Sts: Unknown POV situated at the ceiling and upside-down, shows a physical alteration between passengers. The scene distorts and a blurry frame depicts SCP-X-Odessa's headphones are removed by unidentifiable means. As the view becomes clear again, the entity is shown on all-fours, moving from seat to seat, and crawling under the spaces below.
SCP-X-Odessa begins to clap at its ears.
Music, similar to that from the headphones, is heard from the vantage point of the ceiling near the POV.
8:17 PM|4 Av: Unknown POV captures footage of the exteriors of the F train as it stalls for repairs by the subway station. Concurrent with the speaker system announcing delays, SCP-X-Odessa is shown through the eighth and last compartment window, staring in the direction of the engineers who are inspecting the railway. SCP-X-Odessa convulses and claps its ears.
8:29 PM|7 Avenue Station: Witness-1 raises their phone to the ceiling speaker and records an automated announcement stating, "APOLOGIES FOR DELAYS, ETA INDEFINITE."
8:38 PM|15 St - Prospect Park Station: Witness-2 records footage of an argument a couple has over the uncomfortable heat and smell of urine. An incremental ringing noise displaces their voices. Presumably, the couple became aware of this as they clap their ears and gesture widely. Audio is replaced with 256Hz of pure tones.2
Fig. C Facebook post reads, "Empty, I guess the passengers got off by the last station and walked. Hell, had they stayed, they wouldn't even make the late 12AM ride and no one wants to stay past the end of the route."
9:23 PM|Fort Hamilton Parkway Station: The view opens on the train's exterior. An engineer takes a photo of it and posts the image to facebook (Fig. C). Further down the tunnel, music echoes. The lyrics "sing me to sleep" are heard.
9:25 PM|Church Av: Witness-1 captures footage of SCP-X-Odessa with physical tremors on her wrist. A patina of rust (which was not present since last recording) covers the floors in green and brown coloration. As the camera view ascends, it reveals the entity's exposed ears, which take on the texture of the rusted floors.
The camera view zooms in on vertical lacerations on SCP-X-Odessa's wrists and then at its unnaturally bronze face. Witness-1 asks if the entity requires help. In response the entity clenches a fist and bludgeons its own cheek, which chips and cracks the skin. The sound of train wheels and screeching metal reverberates from each impact.
Due to apparent difficulties in opening and closing its mouth, SCP-X-Odessa pries its lower jaw open and proceeds to jam its fingers inward. Once a grip is established on the roof of the mouth and jaw, the entity pulls at opposite ends. The entity sobs as saliva and blood drips at the borders of the lips. The ligature and cartilage crackle and pop from the pressure.
Finally, SCP-X-Odessa's mouth is agape and emits a low vibration of 90Hz of pure tones.3
Witness-2's camera phone zooms in on nearby passengers who are visibly fatigued and distressed, as their voices are displaced with a high-pitched garble. As the footage proceeds infrequent interjections of 1000Hz of pure tones displace their voices.4
SCP-X-Odessa claps its ears.
Witness-3, who stands inside the eighth and last compartment, records SCP-X-Odessa skin expand and annex the floors, seats, walls, and ceiling. An amber-red substance drips in pulpy clumps from holes on the mouth and slits on the wrists.
9:28 PM|Ditmas Av: An unknown POV is situated from the vantage point of the doorslides of the penultimate compartment. The scene opens on a crowd of passengers who hysterically slam their fists or shoulders against the surface of the doorslides. From the easternmost view, an amber-red mass clumps on the clothing of passengers near it — a leathery band of mobile, string-like tissues stretches over exposed skin.
SCP-X-Odessa claps its ears — after that, it claws, peels, and removes stray dermis and hair.
9:30 - 10:42 PM|Express stops from 18 Avenue Station to Neptune Av: A compilation of events has been gathered by various A/V devices. While passengers, CCTV camera, signaling towers, and concurrent subway trains could not see the F train, warning klaxons were heard on train stop platforms along the F train's route.
