Putting a coin on a train track is illegal in almost every situation, but not for the reason most people assume. The coin is the smallest part of the problem. To place it, you have to step onto railroad property, which is trespassing, and setting any object on an active track can violate state laws against obstructing or interfering with railroad operations. Currency defacement, the reason people usually cite, is the one piece of this that almost never applies.
Trespassing Is the Charge You’ll Actually Face
Railroad tracks and the land on either side of them are private property owned by the railroad company. That corridor, called the right-of-way, often extends 50 to 100 feet from the center of the tracks, though the exact width varies by location and the original land grant. Walking onto it without permission is trespassing, and it doesn’t matter why you went or how briefly you stayed.
Railroad trespass is handled mostly through state and local law. Federal law directs the Secretary of Transportation to develop model legislation for states covering both trespass and vandalism affecting railroad safety.1Office of the Law Revision Counsel. 49 USC 20151 – Railroad Trespassing, Vandalism, and Highway-Rail Grade Crossing Warning Sign Violation Prevention Strategy Most states treat the offense as a misdemeanor, with fines commonly reaching up to $1,000 for a first offense and short jail sentences available in some states. You can be charged even if no train comes and nothing is damaged.
Track Obstruction Laws Raise the Stakes
Placing an object on an active track is a separate problem from being on the track. Most states have specific statutes making it a crime to obstruct or interfere with railroad operations, and legislatures have deliberately chosen not to leave it to individual judgment about what counts as too small to matter. In many states these offenses are felonies, with potential prison time measured in years.
Which charge a prosecutor pursues depends on circumstances: what was placed, where, whether a train was approaching, and whether any damage or disruption resulted. A coin draws less scrutiny than something larger, but the discretion belongs to the prosecutor, not the person who put it there.
The Currency Defacement Question
Ask most people why flattening a penny on a train track is illegal, and they’ll point to a federal law against defacing currency. For almost everyone, this is not the law that applies.
Federal law does make it a crime to alter or mutilate coins, with penalties of up to five years in prison and a fine.2Office of the Law Revision Counsel. 18 USC 331 – Mutilation, Diminution, and Falsification of Coins But the statute turns on one word: “fraudulently.” It targets people who shave metal off coins to sell, alter denominations to pass as higher-value currency, or otherwise manipulate coins to cheat someone. Flattening a penny for a souvenir involves no fraud.
This is why the elongated-penny machines at amusement parks, museums, and tourist attractions operate openly and legally. They do essentially the same thing to a coin that a train wheel does. Nobody tries to spend the result. If you are not trying to defraud anyone, this statute is not your problem.
The Federal Terrorism Statute, in Context
There is a federal law covering railroad interference, 18 U.S.C. ยง 1992, and its penalties are severe: up to 20 years in prison, and life imprisonment or the death penalty if someone dies as a result.3Office of the Law Revision Counsel. 18 USC 1992 – Terrorist Attacks and Other Violence Against Railroad Carriers and Against Mass Transportation Systems on Land, on Water, or Through the Air Its full title tells you what it is actually aimed at: terrorist attacks and other violence against railroad and mass transportation systems. It covers wrecking or derailing trains, placing destructive devices, and similar serious acts.
A federal prosecutor is not going to charge someone with terrorism for a flattened penny. The statute requires knowing conduct affecting a carrier engaged in interstate commerce, and a single coin does not realistically meet its elements. The reason to know the law exists is that it marks how seriously Congress treats railroad interference. The distance between prank and federal felony closes quickly once the object on the tracks becomes larger or more dangerous.
Realistic Penalties If You’re Caught
The practical exposure for someone caught putting a coin on a train track breaks into two tiers.
For the trespass alone, expect a misdemeanor. Fines vary by state and generally run up to $1,000, with the possibility of a short jail sentence. First-time offenders without aggravating factors rarely serve time, but the charge goes on your record regardless of whether a train came near.
If prosecutors add a state track-obstruction or interference charge, the picture changes. These charges can be felonies, especially when the object plausibly endangered safety or disrupted operations. A felony conviction can mean years in prison, larger fines, and the long tail of a felony record: trouble finding work, loss of certain rights, and barriers to housing. If anyone is hurt, penalties escalate again, and civil liability for damages stacks on top of the criminal case.
How People Get Caught
Railroad companies spend heavily on monitoring their property. Most major railroads employ their own police forces with full law enforcement authority, and those officers patrol tracks, yards, and rights-of-way looking for trespassers and interference.
Cameras cover the rest. Federal regulations require outward-facing cameras on the lead locomotive of commuter and intercity passenger trains, with full compliance required by October 2027, and many freight railroads have adopted similar systems voluntarily.4eCFR. 49 CFR 229.136 – Locomotive Image and Audio Recording Devices If you are on the tracks when a train passes, you are likely on video.
When a Minor Is the One Who Did It
This is overwhelmingly something kids do, so the question of what happens when a twelve-year-old gets caught is a fair one. Minors charged with railroad trespass or track obstruction usually go through the juvenile justice system, where outcomes lean toward diversion programs, community service, and education rather than incarceration. A juvenile record still carries weight, and the more serious the charge, the longer that weight lingers.
Parents can be on the hook too. Most states have parental responsibility laws that make parents or guardians civilly liable for property damage caused by their minor children, often up to a statutory cap. If a child’s actions damage railroad equipment or trigger an emergency response, the railroad or local government can pursue the parents for those costs.
The Safety Reality Behind the Law
The legal risk is real, but it isn’t the strongest reason to stay off the tracks. According to preliminary Federal Railroad Administration data, railroad trespassing resulted in 789 deaths and 526 injuries across the United States in 2025.5Operation Lifesaver. Trespassing Casualties by State Trains are faster and quieter than people expect, a loaded freight train traveling at 50 miles per hour needs roughly a mile and a half to stop under maximum braking, and the air displaced by a passing train can pull a person off balance from several feet away.6U.S. Department of Transportation Federal Railroad Administration. Assessment of Potential Aerodynamic Effects on Personnel and Equipment in Proximity to High-Speed Train Operations A coin struck by a wheel can also fly out sideways with enough force to injure anyone standing nearby.
Of the three legal theories involved, currency defacement is a non-issue without fraud, trespassing is the charge most likely to actually be filed, and track obstruction is where the serious penalties live. The margin between nothing happening and a fatal outcome is smaller than most people realize, and that is the part no fine or statute can undo.
