Stopped Freight Train Blocking a Roadway Emergency: Why You Must Never Crawl Under Rail Cars¶

Being trapped in your vehicle or on foot behind a massive, motionless freight train that has blocked your town's railroad grade crossing for two hours, or realizing that an ambulance, fire engine, or your own car carrying a family member in active labor, anaphylaxis, or cardiac distress is cut off by a 3-kilometer-long (2-mile-long) wall of steel rail cars, is a high-stakes community and medical transportation crisis. Under modern "Precision Scheduled Railroading (PSR)" operations across North America, freight trains regularly stretch 2.5 to 4.5 kilometers (1.5 to 3 miles) in length (150 to 250+ cars), exceeding the length of railroad passing sidings and forcing trains to sit dead on main-line grade crossings for hours while awaiting opposing traffic, crew changes, or broken air-brake hose repairs. Faced with a silent train that has not moved a centimeter in 45 minutes, frustrated pedestrians, school children walking home, and panicked bystanders routinely make a fatal mistake: they climb over the steel knuckle couplers between two rail cars or crawl underneath the undercarriage to get to the other side.

Climbing between, over, or underneath a stopped freight train, even one that appears completely shut down with no locomotive visible for miles, kills and amputates hundreds of people every year due to a violent mechanical physics phenomenon known as "Train Slack Action" (Free Slack). Every freight car coupler has 15 to 30 centimeters (6 to 12 inches) of cushioned mechanical play. Across a 150-car train, that adds up to more than 30 meters (100 feet) of total mechanical slack. When a locomotive 3 kilometers (2 miles) away releases its brakes or nudges the throttle, the locomotive horn cannot be heard at your crossing, yet a supersonic shockwave travels down the steel cars at 150 to 300 kilometers per hour (95 to 185 mph), causing the silent rail car above you to lurch 3 to 5 meters (10 to 16 feet) forward or backward in a fraction of a second with zero warning. Instead of risking amputation or death, federal law (49 CFR Section 234.309) places a blue reflectorized Emergency Notification System (ENS) sign on every single railroad crossing post in the United States: calling that 24/7 railroad dispatch phone number and reading the 7-character USDOT Crossing Inventory Number connects you directly to the railroad's Chief Dispatcher, who can order the train crew to "cut the crossing" (split the train) for an ambulance or reroute emergency responders to an open overpass.

Do this now¶

1. NEVER crawl underneath a stopped rail car, and NEVER climb over the knuckle couplers between two rail cars, not even for 3 seconds. A silent freight car can lurch 3 meters (10 feet) instantaneously without a horn blow as air brakes release or slack action rolls down the train. If you are straddling a coupler when the slack wave hits, the telescoping hydraulic draft gear and steel knuckles crush your pelvis or legs like a hydraulic press; if you are under the car, the steel wheel flanges amputate limbs in less than half a second.
2. If you have a medical or fire emergency blocked by a stopped train: call 911 FIRST and tell the dispatcher the exact railroad crossing is blocked by a stopped train. Never try to drive around lowered crossing gates on a multi-track crossing or wait silently in line with a dying patient in your passenger seat. Call 911 (or 112 / 999) immediately and say: "We have a life-threatening medical emergency [state condition] trapped on the [North/South/East/West] side of the blocked railroad crossing at [Street Name]." The 911 dispatch center can simultaneously:
3. Dispatch an ambulance or fire station engine stationed on your side of the tracks (or from a neighboring mutual-aid town on your side of the tracks);
4. Route you or the ambulance to the nearest grade-separated highway overpass/underpass; or
5. Dispatch a medical helicopter (Medevac) if your road is a dead-end peninsula cut off by the tracks.
6. Locate the Blue Metal "Emergency Notification System (ENS)" Sign on the crossing gate post or crossbuck post and call the 24/7 Railroad Emergency Number printed on it. Every public and private highway-rail grade crossing in the United States is legally required to display a blue sign (30 by 23 centimeters / 12 by 9 inches) mounted on the flashing-light mast, gate box, or crossbuck post on both sides of the tracks. Read the two pieces of information on the blue sign to the railroad emergency operator (and to 911):
7. The 24/7 Toll-Free Railroad Emergency Dispatch Phone Number; and
8. The 6-Digits-Plus-1-Letter USDOT National Crossing Inventory Number (for example, 123 456 A).
9. If an ambulance, fire engine, or medical emergency is waiting at the crossing, demand that the Railroad Emergency Dispatcher order the train crew to "Cut the Crossing" (Split the Train) or pull forward immediately. When you call the blue ENS sign number for an active life-safety emergency, the railroad's Network Operations Center (NOC) Train Dispatcher uses GPS mapping linked to that exact 7-character Crossing ID to radio the locomotive engineer inside the cab within 30 seconds. If the train can move forward or backward 200 meters (650 feet) to clear the asphalt, the engineer moves it immediately; if the train is disabled, the conductor walks back to uncouple the knuckle pin ("cut the crossing") and pulls the front half forward to open a gap for the ambulance.
10. If your vehicle is stalled ON the tracks (or trapped between lowered gates) with a train stopped or approaching: GET OUT OF THE CAR IMMEDIATELY, move 30 meters (100 feet) away at a 45-degree angle toward the direction the train is coming from, and call the Blue ENS Sign Number first, then 911. Never stay inside a stalled car on railroad tracks trying to restart the engine. If a crossing gate comes down behind your car, drive right through the fiberglass/wooden gate arm: crossing gate arms are engineered with lightweight shear-bolts specifically so a trapped car can push through them without getting stuck.
11. If a stopped train is blocking a crossing for hours with no emergency in progress, report it to the Federal Railroad Administration (FRA) Public Blocked Crossing Portal at fra.dot.gov/blockedcrossings. While reporting to the FRA portal does not move the train in real time, federal regulators use timestamped Crossing ID reports to identify chronic rail choke points and prioritize federal Railroad Crossing Elimination (RCE) overpass grants.

Phase 1: How to read the Blue "Emergency Notification System (ENS)" Sign and contact the train's dispatcher in 30 seconds¶

Most drivers sit at a railroad crossing hundreds of times without noticing the blue metal sign bolted to the flashing-light post or gate mechanism. Mandated by the Federal Railroad Administration (FRA, 49 CFR Part 234 Subpart E) across every public and private crossing in the United States (and mirrored by Transport Canada Grade Crossings Regulations Section 107 in Canada and Network Rail crossing plates in the UK), that blue sign is a direct red-phone link into the railroad's Train Dispatching Control Center.

Why Calling the Blue ENS Sign Is Faster Than Calling 911 Alone to Stop or Move a Train¶

When you dial 911 and tell a county dispatcher "There's a train blocking Main Street," the 911 operator does not have a joystick connected to the train: they have to look up which railroad owns those tracks, call the railroad's national desk, and try to describe "Main Street in Springfield" (when there are 34 towns named Springfield).

When you read the Blue ENS Sign directly: 1. The 7-Character USDOT Crossing ID (6 Numbers + 1 Letter, e.g., 246 810 B) Is a Unique GPS Pin: - The instant you read those 6 digits and 1 letter to the railroad emergency operator (or give that exact number to your 911 dispatcher so they can relay it), the railroad's computer screen highlights that exact 3-meter (10-foot) strip of asphalt, displays every locomotive within 30 kilometers (20 miles), and opens a priority radio channel directly into the locomotive cab of the stopped train. 2. Major Class I Railroad 24/7 Emergency Dispatch Numbers (North America & International): - While you should always read the specific number printed on the blue sign at your crossing, here are the direct 24/7 emergency dispatch centers for the major freight and passenger railroads:

Phase 2: How "Cutting the Crossing" (Splitting a Stopped Train) works when an ambulance is trapped¶

If a 3-kilometer (2-mile) freight train is stopped across a highway because of a mechanical breakdown, a red block signal ahead, or a federal Hours of Service Act (49 U.S.C. Chapter 211) crew-expiration ("hogging out," where the engineer and conductor have hit their mandatory 12-hour federal legal driving limit and are forbidden by federal law from moving the train until a relief crew arrives by van), how do emergency vehicles get through?

The 3 Operational Solutions Used by Fire Chiefs and Railroad Dispatchers¶

1. Option 1: Locomotive Crew Pulls Ahead or Shoves Back 150 Meters (2 to 4 Minutes):
2. If the train is still occupied by an active crew with air-brake pressure and track authority space ahead or behind, the Railroad Chief Dispatcher grants immediate emergency permission for the engineer to pull forward or shove back far enough to clear the road crossing.
3. Option 2: "Cutting the Crossing" / Uncoupling the Train (10 to 20 Minutes):
4. If the train is too long to pull clear of the crossing without blocking a mainline switch ahead, the Railroad Dispatcher orders the crew to "cut the crossing" (make a cut):
   1. The conductor walks down the ballast from the locomotive cab to the highway crossing;
   2. Closes the pressurized air-brake angle cocks on the two rail cars sitting on either side of the road;
   3. Sets the manual handbrakes on the rear cut of cars so they cannot roll;
   4. Lifts the steel uncoupling lever (cut lever) to unlock the knuckle coupler pin; and
   5. Radios the engineer to pull the front half of the train forward 30 meters (100 feet), opening the asphalt road for the waiting ambulance or fire engine.
5. Option 3: Mutual-Aid "Cross-Track Ambulance Relay" or Helicopter Medevac (Fastest When Crew Is Unreachable):
6. Because walking 2 kilometers (1.2 miles) back from a locomotive cab in deep snow or darkness to manually uncouple a train takes 15 to 25 minutes, fire and EMS departments do not wait passively at the tracks during a cardiac arrest, stroke, or major trauma:
7. Mutual-Aid Dispatch: The 911 center immediately dispatches an ambulance or fire engine from a station already located on the trapped side of the tracks (or from the neighboring town across the county line).
8. Patient Litter Relay (ONLY After Railroad Dispatcher Confirms Train Is Locked Out / Secured with "Red Zone / Track Protection"): In extreme dead-end peninsula emergencies where no vehicle can reach the other side, the Fire Incident Commander contacts the Railroad Chief Dispatcher to place a formal Track & Time / Blue-Flag Lockout on the train with the engineer out of the cab before firefighters ever step onto the ballast.

Phase 3: The mechanical anatomy of a rail car: why climbing over a coupler or crawling under wheels is a death trap¶

People who have never worked around railroads look at the gap between two parked boxcars or tank cars and think: "There is a wide steel bar connecting the two cars with a little platform, I can step right over it in 2 seconds."

Here is why railroad workers are strictly forbidden under federal FRA Workplace Safety Rules (49 CFR Part 218) from ever stepping on a coupler or crawling under a car without locked switches and blue-flag protection:

1. Cushioned Draft Gear (Telescoping Sill Crush Zone):
2. Modern freight cars, especially boxcars, autoracks, and flatcars carrying fragile cargo, are equipped with hydraulic end-of-car cushioning units (sliding center sills) behind the coupler knuckle that slide 38 to 50 centimeters (15 to 20 inches) inward into the frame of the car when bumped.
3. If you step onto the coupler shank or place your hand on the steel striker plate to boost yourself between two cars at the moment a slack wave rolls down the train, the coupler telescopes 45 centimeters (18 inches) straight into the steel sill with 225 metric tons (500,000 pounds) of compressive force, crushing whatever is resting on it.
4. Slippery Grease, Brake Rods, and Tripping Ballast Under the Car:
5. Underneath a rail car sits a maze of low-hanging pressurized air-brake reservoirs, longitudinal brake rigging rods, chains, and bottom discharge valves just 25 to 40 centimeters (10 to 16 inches) above sharp, shifting crushed-granite track ballast.
6. Worse, when air brakes release or apply remotely from the locomotive cab 3 kilometers away, the under-car steel brake rods snap violently sideways under 620 kPa (90 psi) of pneumatic cylinder pressure even before the wheels turn, striking or pinning anyone crouching underneath the car.
7. Why You Cannot "Just Jump Clear" If You Hear the Cars Clank:
8. Slack action travels through a freight train like a row of falling dominoes at 45 to 85 meters per second (150 to 280 feet per second). By the time your ear hears the metallic "BANG-BANG-BANG" of couplers slamming three cars away from you, you have less than 0.25 seconds before the car above your head leaps 3 meters (10 feet) down the track, faster than human neuromuscular reaction time (0.5 to 0.75 seconds).

Phase 4: Why local police often CANNOT ticket a railroad for blocking a crossing (Federal Preemption), and what your town can do¶

A common frustration for residents and local mayors is asking: "Our state has a statute saying a train cannot block a public road for more than 10 or 15 minutes: why doesn't the local police chief arrest the train crew or fine the railroad?"

1. Federal Preemption Under the ICCTA (49 U.S.C. Section 10501(b)) and FRSA (49 U.S.C. Section 20106):
2. In dozens of federal and state Supreme Court rulings across the United States, courts have held that state and municipal laws limiting how long a train may block a crossing (typically 5, 10, or 15 minutes) are federally preempted (struck down as unenforceable) by the Interstate Commerce Commission Termination Act (ICCTA) and the Federal Railroad Safety Act (FRSA), because forcing a train to move faster or break apart regulates interstate rail operations and air-brake safety rules reserved exclusively to the federal government.
3. The Two Practical Solutions That DO Work for Chronically Blocked Neighborhoods:
4. 1. Automated "Blocked-Crossing Sensors" Connected to 911 CAD Dispatch: Dozens of cities separated by busy freight corridors have installed inexpensive radar/optical crossing-occupancy sensors at each railroad crossing that feed live data directly into the 911 Computer-Aided Dispatch (CAD) routing map. Whenever a train blocks Crossing A, the 911 GPS software automatically routes responding ambulances and fire engines over the open overpass at Crossing B, saving 4 to 8 minutes of fatal backtracking during cardiac arrest calls.
5. 2. Filing Mass Community Reports on the FRA Blocked Crossing Portal (fra.dot.gov/blockedcrossings): When residents and local fire chiefs log every multi-hour blockage using the 7-character USDOT Crossing ID, your municipal government can use that official federal dataset to win millions of dollars in USDOT / FRA Railroad Crossing Elimination (RCE) Grants (49 U.S.C. Section 22909) to build a permanent highway overpass or underpass.

Frequently asked questions¶

Why should I call the Blue ENS Sign number on the railroad post BEFORE calling 911 if my car stalls on the tracks?¶

If your car stalls or gets stuck on railroad tracks, an approaching freight train traveling at 90 kilometers per hour (55 mph) takes more than 1.6 kilometers (1 full mile, or 18 football fields) to come to a stop AFTER the engineer pulls the emergency brake lever. If you call 911 first, the county 911 operator has to figure out which railroad company owns the track, look up their phone number, call the railroad, and try to explain which street you are on, a relay that takes 3 to 6 minutes, by which time the train has already smashed into your vehicle. Conversely, calling the 24/7 phone number printed on the Blue ENS Sign at the crossing connects you directly to the railroad's Train Dispatcher in 15 seconds: the moment you read the 6-digit-plus-1-letter USDOT Crossing ID on that sign, the dispatcher puts an immediate emergency stop broadcast out to every train on that track.

If my car is on the tracks and a train is coming toward me, why do safety experts say to run TOWARD the oncoming train at a 45-degree angle?¶

It sounds counterintuitive to walk or run in the general direction of an oncoming train, but it is pure physics: when a 15,000-ton locomotive strikes a stalled car or truck at 80 kilometers per hour (50 mph), the car explodes into flying metal shrapnel, glass, and engine parts that are hurled FORWARD down the tracks in the exact same direction the train is traveling (just like a baseball hit by a bat). If you run away from the train down the tracks or stay parallel to the rails in the direction the train is moving, the flying wreckage of your own car will hit you from behind. Running away from the tracks at a 45-degree angle back toward the direction the train is coming from puts you safely behind the point of impact and out of the forward debris cone.

What if the crossing gates are stuck down and lights are flashing for 20 minutes, but there is NO train anywhere in sight?¶

Never assume the signals are "just broken" and drive around the lowered gates, especially if there are two or more tracks or a curve nearby. Railroad crossing gates operate on a "fail-safe" closed-track electrical circuit: if a rail breaks, a wire is cut, a maintenance crew is working down the line, or a distant train is approaching, the gates drop automatically. Instead of driving around the gates, pull over safely, walk to the crossing post to read the Blue ENS Sign, and call the 24/7 Railroad Emergency Number with the 7-character Crossing ID to report a "Malfunctioning Active Warning Device (49 CFR Part 234)." The railroad dispatcher can tell you on the phone whether a train is approaching and will immediately dispatch a signal maintainer and local police officer to flag traffic safely through the intersection.

Is it true that in Canada a train is legally forbidden from blocking a road crossing for more than 5 minutes?¶

Yes. Unlike the United States, where federal courts have largely preempted state time limits on blocked crossings, Canada has an enforceable federal regulation under Section 97 of the Transport Canada Grade Crossings Regulations (SOR/2014-275). Under Section 97(1), it is prohibited for railway equipment to be left standing on a crossing surface, or for switching operations to be conducted, in a manner that obstructs a public grade crossing, including by activating the gate arms, for more than 5 minutes when vehicular or pedestrian traffic is waiting to cross. In addition, under Section 97(2), if an emergency vehicle (ambulance, fire, or police) requires passage across a grade crossing in Canada, railway employees must take immediate action to clear the crossing, regardless of how short a time they have been stopped.

Can I walk AROUND the very front of a stopped locomotive or the very back of the last car if I stay 3 meters (10 feet) away?¶

No. Never walk across the tracks within 15 meters (50 feet) of either the front nose of a stopped locomotive or the rear coupler of the last car ("the EOT / End-of-Train device"). First, a locomotive engineer sitting 4.5 meters (15 feet) high in the cab has a massive blind spot extending 10 to 15 meters (35 to 50 feet) directly in front of the locomotive's steel snowplow nose and cannot see a pedestrian stepping across the rails. Second, as explained in the Slack Action warning above, the rear car of a stopped freight train can violently whip backward 3 to 5 meters (10 to 16 feet) in less than half a second when the locomotive 3 kilometers away bunches the slack to start moving. Only cross at a designated public crossing after the train has completely cleared the intersection and the gates have fully risen and lights have stopped flashing.
