 Item number SCP-5850 Clearance Level 3, Confidential Containment Class, Keter Disruption Class 4, Echie Risk Class 5, Critical Special Containment Procedures Due to the nature of SCP-5850, containment is not possible at the present time. One personnel tasked with monitoring SCP-5850 are to be granted administrative access to all train traffic control systems operating within the United States. Reports concerning SCP-5850 are to be stored within a dedicated server and evaluated weekly. These reports must include the following information. SCP-5850's current, prior, and all previously reported locations. Material changes in velocity, magnitude, or physical structure. Copies of public material concerning SCP-5850. This material includes, but is not limited to, photographs, videos, and police reports. Dedicated observation of newly discovered SCP-5850A instances. Reports of SCP-5850's current Ulf value. In the event that SCP-5850 travels through a populated area, Foundation personnel are to reroute or stop all incoming traffic, so that no individuals are affected by the anomaly. In the event that these procedures fail, and any human subject perishes to the SCP-5850, the confiscation of any recording devices, along with the amnestidization of the populace that observed SCP-5850 is required. Description SCP-5850 is a passenger locomotive currently in transit within the United States, and has never been observed to stop or decelerate under any circumstances. SCP-5850 has plowed through all known obstructions, with no loss in velocity. SCP-5850 has also been observed to maintain its speed, even with the absence of rails. The current cause of this remains unknown. Upon its discovery in 1924, SCP-5850 maintained a velocity recorded at approximately 120 km per hour, and has since accelerated an additional 26 times to a current velocity of 145 km per hour. SCP-5850 has also been classified as an anti-excentential object due to its effects on dimensional energy and localized spacetime. SCP-5850's physical structure consists of steel, aluminum, zinc, and plastic. Along both sides of SCP-5850 reeds, Investago Railroad Company, which spans 70% of its total length. Even passenger cars are attached to SCP-5850, which also contains SCP-5850-A instances. SCP-5850-A refers to 24 indistinct humanoid entities, observed throughout the entirety of SCP-5850. These entities manifest after SCP-5850 collides with human subjects, followed forward with a flash of light. Recent research efforts are to ascertain the established connection between these entities and their perceived effect on SCP-5850's speed. These entities do not appear to require sustenance. Addendum 5850-1 On March 14, 2020, Senior Researcher Kenneth Williams submitted a request for experimentation on SCP-5850. When asked about his reasons, Researcher Williams submitted a report titled, All Values and Their Hypothetical Effect on Spacetime, which has been attached to Addendum 5850.2 of this document. Listed below is the video log after his report was formally accepted. Video Transcript 5850-A Video Log Date? March 26, 2020. Note The following video was recorded to observe and analyze SCP-5850. This recorded was taken from the perspective of Senior Researcher Williams. Accompanying him is Dr. Reigns, Mobile Task Force N-D-1 Captain Russells and MTF N-D-1 Sergeant Stevenson. The research team was also given several other devices per Researcher Williams request. Begin log. Video recording begins in an MTF N-D-1 designated vehicle traveling northbound. In front of the camera is Dr. Reigns. The perspective pans around the interior of the vehicle, introducing MTF N-D-1 Sergeant Stevenson and Captain Russell who sit alongside. Are you sure you understand what you're doing, Kenneth? Of course. Why do you ask? Well, it's just what you're proposing. Do you really think the counters are going to work? I couldn't tell you. Sergeant, are we getting close? Stevenson looks out the left window. Almost. Give us another minute. We'll let you know when we see. For now, stay cozy. Silence for 15 seconds. Laura, you know what you're doing, right? No, not really. You haven't really told me anything. I know, I know. But trust me, this is important. We've gone for years without fully understanding what this thing is. Hopefully, if the math checks out, this test should tell us something. You keep saying that, but I still haven't heard you actually say what it is you're talking about. It's just a hunch, Laura. A hunch about what, Ken? Hey fellas, we're at the location. The vehicle turns sharply to the right before coming to a complete stop. All four passengers disembark, and the camera pans across a straight road leading to a railroad crossing. Williams and Reigns run to the railroad crossing, each carrying a pair of long aluminum rods with a bulbous tip. How far are we from SCP-5850? We're about 25 kilometers away at this point. Alright then. Fuck. Laura, let's get this equipment set up. You remember how I showed you, right? Good. Let's hurry then. We've only about ten minutes. Williams and Reigns begin setting up the Ulf counters in four separate locations, which corner the railroad crossing. Afterward, they connect each counter using a physical wire before bridging them together onto a computer terminal located ten meters away. Williams sits near the terminals, as Reigns continues setting up the Ulf counters. Laura, how are we looking so far? I'm almost finished. How long do we have left? Less than five minutes. Come on, you can leave them alone. They should be good as they are now. Laura, please. There's no reason to risk your life over them. Reigns vacates the area and moves to Williams. You better hope this hunch of yours is right, Kenneth. Let's fucking hope so. Alright, I'm turning it on now. The computer terminal boots on and begins running an unknown program. In the distance, SCP-5850 is horned blairs. Alright, you son of a bitch. Come to daddy. Is that really necessary? Sorry, what? I'm having a hard time hearing you do this loud ass fucking train. SCP-5850 arises at the location. As it progresses, several instances of SCP-5850-A are visible within its interior. SCP-5850-A does not react to Williams or Reigns, despite their proximity. It takes approximately two minutes for SCP-5850 to pass. During this time, Williams' computer terminal begins to flash. This ends when SCP-5850 exits the area. Well? Did you learn anything? Williams did not respond to Reigns, continuing to stare at the computer screen. Well, did you? Ha ha ha ha, yeah, yeah, fucking did. Well, what did you find? This...train. At first, I thought it was weird that the counters were picking up dimensional values. But then... Quit with the nonsense, Kenneth. Laura, take a look at these readings. Reigns walks to the terminal, leaning forward to observe the readings. We were right. EC-violation notice 5850.A, copy of ethics committee policy violation for Kenneth Williams and Laura Reigns.

You haven't been answering any of my texts, and I haven't been able to stay home long enough to talk to you. Are you okay? You sounded really excited about what happened. I know you've been submitting stuff to the IRFs, so I know you haven't died. Just let me know what's happening, okay? We're in this together. I know you're busy, so please respond when you can. I'm getting worried, Laura. I'm sorry about not getting back to you. You don't need to worry. I haven't become a zombie or anything. It's just… With what I've discovered, my excitement has gotten the best of me. I didn't mean to leave you in the dark. I'll be sending you with some more information later. I'll be home later if you want to talk about it. This could be revolutionary if my theories are right. It's exciting to me, that's all. I just needed some time alone for a week or so to get all my thoughts into one place. Tell you what, let me take you to dinner sometime. It'll be just like we used to. P.S., after dinner, why don't we take the fun back home? It'll be just like we used to. If we're going to do it like we used to. At least go to the pharmacy before you come home. I know how fast you can finish. Addendum 5850-2 Document 303-EM-5850.b Both values end their theoretical effect on spacetime. Status approved. Author. Kenneth Williams. Laura Reigns. Synopsis. For millennia, the human race has fantasized and dreamt of the places we would go to once we perish from the earth. Religions. Folklore. And even scientific studies have searched far and wide to ascertain the truth behind death. This simple question continues to plague us. What happens after we die? However, with the introduction of SCP-5850, the answer to an afterlife might have been inadvertently solved. Once we believed that our dimension, humanity's perception of reality, was stagnant and unchanging. With the introduction of anomalies such as SCP-3082 and SCP-4051, we now realize that dimensions such as ours can exist outside of our preconceived notion of reality. These anomalies can access, change, or fundamentally shift other dimensions to fit their needs. SCP-5850 is no exception. For these other dimensions, we have issued values that help reference their existence to our very own. Our dimensions set to the value of zero, with other dimensions spanning values from one to infinity. With dimensions closer to zero, we understand that they better relate to ours. But what would happen if a dimension held a value below zero? With the introduction of SCP-5850, we realize that dimensions are capable of doing exactly this. We understand that in order for dimensions to properly exist, organic matter must be able to fundamentally operate. With the introduction of these anti-dimensions, which are capable of possessing anti-spacetime, it should only make sense that non-living matter must fundamentally operate there as well. Because of this, we have issued a unit of measurement, specified as Ulfs, which measures the value of these anti-dimensions. Ulf values also measure similarly to current dimensional values, with numbers closer to zero relating to that of our own. SCP-5850's Ulf value measures negative 0.001 at the time of this writing. If this theory is correct, the concept of an afterlife purely resides in these anti-dimensions. There could be an infinite amount of afterlives, each operating in their own ways. Perhaps heaven and hell and Judeo-Christian holy books are real, but differing in their Ulf values. More research is required to understand more about these anti-dimensions. Video transcript 5850.b Video log Date May 2, 2020 Note, the following video was recorded during the measurement of SCP-5850's Ulf value. Footage recorded was taken from the perspective of Senior Researcher Williams, accompanying him as Dr. Reigns, and MTF-ND-1 Private Second Class Ryan Smith, who was away from the area. Begin log Video recording begins on a railroad split rail, with the camera facing towards the central point, in front of the camera is Dr. Laura Reigns. Hey, are you getting explained why we're at this divide? I thought the plan was to go somewhere more controlled, like, a clearing or something. It was, but we missed the opportunity. We just got some news that someone was hit. The place had been amnesticized, but now the train's faster than it was before. How much faster are you talking about? If it stayed consistent with the other ones, I'd say around 144 or 145 kilometers per hour. But besides that, this is the only other way it's heading that isn't a city or a town, so basically we're stuck here. Shit, how much longer do we have? A few minutes by this point. We need to hurry, though. The counters still need to be placed in the right areas. Could you set them over there? Yeah, I can. Thank you, Laura. Reigns heads towards the designated area and begins placing the elf counters. After a moment, Kenneth walks towards a computer terminal located 10 meters away. Hey, are you okay? Of course. Why wouldn't I be? It's just… you never answered my texts last night. Kenny, I'm fine. I know you're excited about this project, but… now isn't the time to discuss what's wrong with me. We can talk about it later. Are you sure? Fuck, it's already here. Laura, get away from the tracks! I hear it, Kenny. I'm trying. I just need to set the last two counters, okay? Hurry then! After several seconds, Reigns moves away from one of the elf counters and runs to the opposite side of the tracks. She quickly unfolds the final elf counter, quickly positioning it near the train tracks. Her body is directly across the edges of the track. SCP-5850 is visible, and it's estimated to be approximately 2 kilometers away at this point. You need to pick it up! Laura! Fuck, just another second. Williams begins to quickly walk towards Reigns as she finishes with the elf counter. Once completed, Reigns quickly turns around to Williams. Alright, I'm cunt. Williams begins running towards Reigns. Several seconds later, SCP-5850 impacts Reigns before she can finish her sentence. At the same moment, Smith was able to intercept Williams before he was able to get in closer. Williams remains silent for several seconds afterward. As SCP-5850 leaves the area, another instance of SCP-5850-A appears in the final passenger car.

Signed Malcolm Dormansk Six days after the violation noticed 5850.C, Researcher Kenneth Williams and several ALF counters were reported missing. This led to an official investigation of which Researcher Kenneth Williams was located in her Las Vegas, Nevada. Attached below is the affiliated video log taken during the investigation. The transcript, 5850.C, Video Log, Date, August 14, 2020 Note, the following video was recorded while four MTF-ND1 members were searching for Researcher Kenneth Williams. The recorded footage was taken from the perspective of MTF-ND1 Captain Russell. Accompanying him is MTF-ND1 Sergeant Stevenson, MTF-ND1 Corporal Chad Mayers, and MTF-ND1 Private Second Class Ryan Smith. Begin Log Video recording begins with MTF-ND1 approaching a bridge that overlooks a railroad track. Further ahead, a man can be seen on the bridge. Approach slowly. Mayers. Watch S6. Smith. Get to the other side. Stevenson and I can handle the POI. Make sure he's set to non-lethals. Shoot if required. Roger. Russell progresses towards the bridge. Stevenson follows on his right side. Mayers and Smith step out of the frame. MTF-ND1 continues to approach the figure. Are you in position, Smith? Affirmative. Standing by. Acknowledged. Hold your position. Establishing contact with POI. Russell signals Stevenson to hold his position as he continues towards the figure. It was hereby referred to as Williams. Once within a range of 10 meters, Russell stops moving. Freeze! We're here to escort you to a safer location. If you refuse to listen, we will use force. Hands up, Kenneth. Russell raises his weapons towards Williams. At the same moment, a blaring horn is heard nearby. Williams begins to laugh. Russell approaches slowly. I said hands up! We will engage if you don't cooperate. Just leave me alone. Don't you see what I'm trying to do? Russell advances. He is approximately 5 meters away from Williams. Along the edge of the frame, Smith also advances. Kenneth, step away from the edge of the building and walk towards me slowly. Williams takes a single step backward, leading his body to the edge of the bridge. Russell continues to approach Williams and is now 4 meters away. The sound of a horn can once again be heard, this time sounding louder. You don't understand, Laura isn't dead. Look, I know I sound crazy and stupid or whatever, but I know I'm right. I've been pouring over the research for months. This is the only other place I know of where I can get close to SCP-5850. If I don't do it now, it'll only take more time before I travel somewhere else that I can get to, you have to let me at least try. That won't be necessary, either you do as I order you or we'll be forced to shoot. Look, none of the documents will tell you the truth. Laura and I spent so much wasted time. We would stay up all night for days, just looking over numbers in our bedroom. It was, it was peaceful. I'm sorry for you, Kenneth, but how does any of that right now solve anything? You don't understand, but you know what she was going to tell me before she died. We can talk about that once we're back home, but right now you're endangering yourself and plenty of other people. We need you to come with us. She, she had a miscarriage. After we spent forever trying to have one, I found the reports in her locker. Don't you get it? I can get her back. I know I can. I just need more time. You have to let me try. Nothing you're saying right now is making any sense. You're upset. I get it. But if anything were to happen to you, we would all be at a loss. Just let me do this. I have all the equipment set up. I just need this final test. You need to come with us. This is your final warning. SCP-5850 becomes visible behind Williams. Russell advances until he is approximately two meters away. Fine, so be it. I guess my only other option is to go where she is. Williams jumps backwards, going over the wall of the bridge. Russell attempts to fire at Williams, but is unsuccessful in incapacitating him. Williams falls to the ground in front of SCP-5850. Seconds later, SCP-5850 impacts Williams. God! Dammit! Stevenson, get Mayas. Tell him to bring a buddy back. End log. Following this incident, an additional SCP-5850-A was discovered sitting there another instance.
