question: How do people (not in cars) get stuck on train tracks?
comment: I suspect you're misinterpreting the stories. It feasibly could be possible that someone could get their foot jammed between a rail and a tie and not be able to extricate themselves, but I imagine that is extremely rare. When people not in vehicles are killed by trains it's almost always because either 1. they were trying to cross the tracks in front of a train and misjudged the trains speed 1. they were trying to stand too close to the train as it passed 1. they were between two trains going in opposite directions on parallel tracks (that one's a particularly brutal variation on #2) 1. they were incapacitated on or too near the tracks for some reason, e.g intoxication 1. some combination of the above, e.g. intoxication can certainly help lead to 1-3
passages: The most common obstructions encountered are road vehicles at level crossings (grade crossings); malicious persons sometimes place materials on the rails, and in some cases relatively small objects cause a derailment by guiding one wheel over the rail (rather than by gross collision).
  
  Derailment has also been brought about in situations of war or other conflict, such as during hostility by Native Americans, and more especially during periods when military personnel and materiel was being moved by rail.

   BULLET::::- On June 14, 1987, a train that was pulling into the loading station malfunctioned and slammed into the rear of the other train inside of the roller coaster station. A total of 56 passengers were involved in the accident, but only 8 were taken to the hospital for injuries.
  
  BULLET::::- On July 17, 1999, two cars of a seven-car train derailed due to severe internal metal fatigue in a support post, stranding 18 people. Two were immediately taken to a hospital, and six went later. None of the injuries were life-threatening.
  
  Section::::Incidents.:Screamroller.
   The incident occurred while a group of passengers were late at night purchasing their sleeping car places from the conductor who stood on the station platform at the entrance of the car. The platform was about the height of the car floor, and there was of course a narrow space between the platform and the car body. There was some crowding, and I happened to be pressed by it against the car body while waiting my turn. In this situation the train began to move, and by the motion I was twisted off my feet, and had dropped somewhat, with feet downward, into the open space, and was personally helpless, when my coat collar was vigorously seized and I was quickly pulled up and out to a secure footing on the platform. Upon turning to thank my rescuer I saw it was Edwin Booth, whose face was of course well known to me, and I expressed my gratitude to him, and in doing so, called him by name.
   Passengers further back in the train heard explosions. "The thing that precipitated people really starting to freak out and break the glass and open the door was there was a loud 'bam,' explosion-type thing," said Fred Buonocore, who was in the fourth car. "And once we jumped off the side, there was another explosion to a lesser degree." At the very rear, passengers said they felt only a small jolt. "It felt not even like a short stop, and then the train just completely stopped," said Neil Rader, who was sitting in the middle-back of the train.
   According to "The New York Times", "One of the cars of the wrecked train was split in two and left in halves on either side of the track. The butchery of the passengers was one of the most frightful things in the history of railroading. They were cut into pieces and portions of their bodies scattered all along the track"
   At the house of Mr. Temples, about a mile from the bridge, are several wounded men, amongst whom is Mr. W. R. Norman, an aged and very intelligent and prominent gentleman, who resides near [Hickory] station. He fully corroborates the statement of the other passengers in regard to the care and caution used by the conductor, before reaching the last Chunky bridge, at which time, he says, they were running faster than at any previous. When the train ran off the track, he was in the car nearest the engine, and he thinks that not more than three escaped out of that car. He went to the bottom, in about fifteen feet of water, but rose to the surface with the fragments of the broken car, and with great difficulty succeeded in getting to the shore. His collar-bone is broken, his leg badly hurt, and he is injured internally, but will recover.
   Soon a group of people started coming forward who claimed that they had been injured in train crashes, but had no obvious evidence of injury. The railroads rejected these claims as fake.
   BULLET::::- 20 June – "United States" – Three refrigerated cars carrying butter on an East Penn Railroad train derailed in Sellersville, Pennsylvania.
  
  BULLET::::- 27 June – "United States" – A southbound New York City Subway train derailed then caught on fire near 125th Street. The derailment, caused by improperly secured replacement rails, resulted in 39 minor injuries.
   Train track (mathematics)
  
  In the mathematical area of topology, a train track is a family of curves embedded on a surface, meeting the following conditions:
  
  BULLET::::1. The curves meet at a finite set of vertices called "switches".
  
  BULLET::::2. Away from the switches, the curves are smooth and do not touch each other.
  
  BULLET::::3. At each switch, three curves meet with the same tangent line, with two curves entering from one direction and one from the other.
   BULLET::::- April 25, 2011, Disneyland Paris: Five guests were injured when a piece of scenery fell onto a passing train. One guest, a 38-year-old man, was seriously injured and transported to a Paris hospital, while the other four were treated at the scene.
  
  BULLET::::- October 27, 2011, Disneyland Paris: Two cars derailed as one of the ride's trains passed slowly over a flat section of track. Two guests were slightly injured, and the ride was subsequently closed for inspections.
   BULLET::::- On June 28, 2008, a 17-year-old male from Springfield, South Carolina was decapitated by the passing train after he climbed over two six-foot fences and entered a restricted area. Reports said that the victim was trying to retrieve his lost hat. Additional eyewitnesses stated that the victim and a companion, who also entered the restricted area but was uninjured, were trying to take a shortcut back into the park after leaving the park for lunch.

   Because railroad companies can only patrol stopped trains, freight-hoppers embark and disembark while the train is in motion to avoid bulls. But freight train cars are not designed for human riders; hopping on (or off) moving trains bears serious risk of dismemberment or death. In March 1899, Welsh "tramp-poet" W. H. Davies lost the lower part of his right leg after jumping a train at Renfrew, Ontario. The incident is recounted in his 1908 book "The Autobiography of a Super-Tramp".
  
  More than a century later, train hopping is still a safety concern.

   [The eighth car] "split the switch," and before the passengers jammed within it could raise their cries of terror it was skidding half sideways down the track.
  
  A hundred feet farther on it crashed into one of the great steel pillars which keep the street above from tumbling in upon the tunnels.
   Section::::Causes of the wreck.:Train speed.
   The phenomenon of riding on the outside of trains came with the appearance of the first railway lines. On a series of first railroads, riding on rooftops and footboards of trains was common, but over time, starting from the second half of the 19th century, with an increase in the sizes and speed of trains, passenger coaches began to be produced fully covered and insulated from streets with a placement of all passenger seats inside carriages in order to improve the safety of passengers and prevent people falling from a moving train. However, some individuals continued riding on the outside of trains to travel without having a ticket.
   It is extremely rare, the report said, for displaced sections of "any" rail to puncture and enter a rail vehicle during an accident, as had happened at Valhalla. During his interview with investigators, Metro-North's power director told them he believed the third rails were designed to break up in accidents and fail to the side, away from the train, since they had done so during the 1984 single-fatality accident at that same crossing. But in this case, with only two exceptions, the third rail's 6-foot (2 m) sections had largely remained joined in larger sections averaging in length, weighing a ton (800 kg) each, as they accumuluated in the first and second cars.
   Section::::History.
   BULLET::::- An episode of the television show "30 Rock" entitled "Subway Hero" features Dennis Duffy, a recurring character, as a citywide hero after emulating the actions of Wesley Autrey.
  
  BULLET::::- The January 2011 premiere of "House MD", shows a man named Jack Nash who heroically saves a woman stuck in the throes of a seizure on the subway tracks. Nash, deemed by the press "The Subway Hero," collapses afterward from injuries unrelated to the train incident.
   In the train yard at Union Station, towerman John Feeney in K Tower set the switches to shunt the "Federal Express" onto Track 16. But when the train raced past him at high speed, he telephoned the stationmaster's office. Clerk Ray Klopp picked up the phone. Feeney shouted, "Runaway on Track 16!" Klopp looked up to see the train racing directly toward his office. He shouted, "Run for your lives!" Then he and the other clerks ran out of the office as fast as they could. (They had just 20 seconds to get out of harm's way.) Aboard the train, conductor Thomas J. Murphy ran through the train from end to end, shouting at the passengers to get down as low as they could on the floor or on their seats.
   There was a wreck on July 11, 1911, in which the Federal Express plunged down an 18-foot embankment, with at least 14 fatalities. The train was also carrying the Dodgers baseball team.

   Freight trains are sometimes illegally boarded by individuals who do not have the money or the desire to travel legally, a practice referred to as "hopping". Most hoppers sneak into train yards and stow away in boxcars. Bolder hoppers will catch a train "on the fly", that is, as it is moving, leading to occasional fatalities, some of which go unrecorded. The act of leaving a town or area, by hopping a freight train is sometimes referred to as "catching-out", as in catching a train out of town.

raw_presuppositions: People who are killed by trains got stuck on the train tracks. Individual humans outside of vehicles should get stuck in train tracks. 
raw_corrections: People who are killed by trains couldn't cross quickly enough or were incapacitated. It is actually quite difficult for a human to get stuck in a train track without a special circumstance.
