Евакуација метроа и воза из шина¶

A subway collision, commuter rail crash, or high-speed train derailment produces violent kinetic forces, sudden total darkness, flying glass, and immediate passenger panic. However, transportation safety investigations worldwide confirm a critical fact: in underground and electrified rail incidents, more surviving passengers are killed or critically injured after the crash by stepping onto live high-voltage third rails, walking into the path of oncoming trains on parallel tracks, or inhaling toxic tunnel smoke during uncoordinated self-evacuations than during the initial derailment impact itself.

What you do in the first sixty seconds after the wheels leave the track determines your survival. Knowing how to brace during deceleration, when to shelter inside the steel railcar versus when to climb out, how to identify lethal 750-volt third rails and 25,000-volt overhead catenary wires, and which direction to walk in a smoke-filled subway tunnel will get you and those around you to safety.

Уради ово сада¶

1. Brace low until all train motion and secondary impacts stop completely: If seated, plant both feet flat on the floor, lean forward, and clasp your hands behind your head/neck. If standing in a subway car, drop immediately to your knees or sit flat on the floor and grip the base of a vertical metal stanchion pole with both hands.
2. Stay inside the railcar unless fire, dense smoke, or rising water forces you out: The steel body of a passenger railcar shields you from live high-voltage wires, trains moving on adjacent tracks, and unstable tunnel debris. Wait for the conductor's announcement or use the passenger emergency intercom next to the doors.
3. Treat every third rail, cover board, and dangling wire as 100 percent live and lethal: Never touch or step on the raised electric third rail (600 to 1,000 volts DC), its wooden or fiberglass protective cover board, or any fallen overhead catenary wire (11,000 to 25,000 volts AC).
4. Evacuate through the end doors between cars or onto the raised wall catwalk: If fire or heavy smoke requires immediate evacuation, walk through the front or rear end doors into an adjacent safe car, or climb directly onto the raised concrete emergency walkway along the tunnel wall rather than jumping 1.5 meters (5 feet) out a side door onto the third rail.
5. Walk single-file between the two running rails if on the track bed: If no raised wall walkway exists and you must walk on the track floor, stay strictly in the center between the two steel running rails of your own track, never crossing over to parallel tracks where high-speed trains may still be approaching.
6. Head upwind against the airflow if smoke is present and locate a Blue Light Station: Move low beneath rising smoke toward fresh incoming air, and look for a blue lantern light on the tunnel wall marking an emergency telephone and traction-power cutoff switch.

Surviving the impact: crash biomechanics and brace positions¶

Unlike passenger cars, most urban subways, light-rail trams, and regional commuter trains do not have passenger seatbelts, and up to two-thirds of rush-hour subway riders are standing when an impact occurs. When a train moving at 80 km/h (50 mph) derails or strikes an obstruction, unbraced standing passengers are thrown the length of the car at highway speed, striking metal poles, glass partitions, and other riders.

How to brace in the 2 to 5 seconds after feeling derailment vibration¶

A train almost never stops instantaneously; when wheels drop off the steel rail onto wooden or concrete ties (sleepers) and stone ballast, you will first hear a deafening metallic roar and feel violent vertical bouncing for several seconds before the cars jackknife, tilt, or collide with a tunnel wall.

• If standing in a subway or commuter car: Do not try to remain standing by holding an overhead hanging strap; your upper-body grip strength cannot resist a 5G deceleration force. Immediately drop flat onto the floor or onto your knees, press your back or shoulder tightly against a fixed seat base or bulkhead wall facing away from the direction of travel, and wrap your arms around the bottom of a vertical floor-to-ceiling pole while tucking your chin to your chest.
• If seated facing forward (in the direction of travel): Place both feet flat on the floor behind your knees, bend forward at the waist so your torso rests near your thighs, press your forehead against the padded seatback in front of you, and lock your hands behind the back of your neck to stabilize your cervical spine and block flying glass.
• If seated facing backward (opposite the direction of travel): Backward-facing rail seats are biomechanically the safest seats in a frontal collision because the seatback supports your entire spine and head during primary deceleration. Sit all the way back with your spine and the back of your head pressed firmly against the headrest, plant your feet wide on the floor to brace against the secondary rebound, and cross your arms over your chest or face.
• Shield your eyes and airway from brake and concrete dust: As soon as a train derails in an underground tunnel, decades of accumulated steel brake dust, silica ballast dust, and shattered window glass fill the cabin air. Pull your shirt collar, jacket, or scarf up over your nose and mouth and squint or shield your eyes until the dust settles.

Stay inside vs. evacuate: the golden rule of rail safety¶

Once the train comes to a halt and emergency backup battery lights flicker on, natural human claustrophobia makes passengers want to pry open the doors and jump onto the tracks. Resist this urge and stop fellow passengers from forcing doors open unless a life-threatening hazard is inside your car.

Why staying inside the car is almost always safer¶

• Ефекат Фарадејевог кавеза против високог напона изнад главе: Када електрични приградски или међуградски воз искочи из шина, жица контактне мреже од 25.000 волти изнад главе често пуца и прелази преко металног крова путничког аутомобила. Све док останете потпуно унутар металног вагона, струја тече безопасно око спољашње коже до земље. Ако изађете кроз врата и додирнете метални рукохват док стављате једну ногу на земљу, постајете пут до земље и моментално ћете бити погођени струјом.
• Ударци брзих возова на паралелним колосецима: На железничким ходницима са више колосека и експресним тунелима метроа, возови на суседној прузи удаљеној само 1,2 метра (4 стопе) можда и даље јуре ка месту несреће брзином од 100 до 200 км/х (60 до 125 миља на сат) пре него што дође до централног протока.
• Кашњење аутоматског искључивања снаге вуче: Центрима за контролу железнице треба неколико минута да потврде инцидент, зауставе суседне возове и даљински искључе струју са треће шине преко сектора тунела.

5 услова који захтевају хитну самоевакуацију¶

Отворите врата за случај опасности и оставите воз без надзора посаде само ако:

1. Видљиви пламен или врелина се шире унутар или директно испод вашег вагона.
2. Густ, загушљив дим пуни ауто и не можете да уђете кроз крајња врата у аутомобил без дима.
3. Вода се активно диже у колима (на пример, у подводном речном каналу, обалском насипу или у делу метроа који је поплављен).
4. Опасно цурење хемикалије или дизел горива из суседног теретног или локомотивног вагона цистерне се накупља око вашег аутомобила са јаким хемијским испарењима.
5. Ауто се нестабилно клати на ивици урушеног насипа или пробоја у структури где останак унутра ризикује тренутни пад.

Објашњене електричне опасности на стази и тунелу¶

Свака особа која се вози подземном железницом или приградским возом треба да разуме физички распоред колосека како би тачно знала где живи смртоносна електрична енергија и где је безбедно поставити ноге.

Step-by-step protocol for evacuating a railcar safely¶

If fire, smoke, or crew orders require you to evacuate the train inside a tunnel or along an open right-of-way, follow this strict sequence to prevent falls and electrocution.

1. Choose the safest exit door in this exact priority order¶

1. First choice: End doors between railcars (Inter-car gangway): If only one car has smoke or a small electrical fire underneath it, open the center door at the end of the car and walk across the threshold plate into the next car of the same train, closing the heavy fire-rated end door behind you. You stay completely off the tracks and out of danger.
2. Second choice: Side door opening directly onto a raised tunnel benchwall / catwalk: Look out the windows on both the left and right sides of the car before pulling any emergency door release. Most subway tunnels have a raised concrete emergency walkway (benchwall) along one wall of the tunnel, while the third rail runs along the floor on the opposite side. Always open the door that faces the raised concrete walkway so you can step straight across onto the catwalk without dropping down to track level.
3. Third choice: Front or rear cab end door with deployable ladder/ramp: If you must descend to track level, the end doors at the very front or very back of the train align directly with the safe center space between the two running rails and often feature built-in fold-down steps or evacuation ramps.
4. Last resort: Side passenger doors down to track ballast: Standard train floors sit 1.2 to 1.5 meters (4 to 5 feet) above the uneven stones of the track bed, and the third rail often runs directly underneath one side of the car just 30 centimeters (12 inches) outside the wheels. If you must exit a side door to the ground:
   • Look down with your phone flashlight before moving and ask loudly: "Is the third rail on this side?" If you see the raised third rail and its wooden/fiberglass cover board directly below the doorway, do not use that side door; open the door on the opposite side of the car instead (after checking rigorously that no train is approaching on any adjacent track).
   • Do not jump out upright. Sit down on the edge of the doorway floor, turn around on your stomach, grip the inside floor edge or side handrails with both hands, and lower yourself down feet-first until your shoes touch the stone ballast.

2. How to operate emergency door and window releases¶

• Pneumatic or electric side doors: Look directly above the door header or on the side pillar beside the doors for a red handle behind a clear plastic flap labeled Emergency Door Release. Pulling the handle down (and sometimes rotating it) vents air pressure or disengages the mechanical lock so you can push the two door leaves apart by hand. Note that on most modern trains, pulling the emergency door handle while the train is still moving automatically triggers the emergency brakes; wait until the train is stopped inside a station or safe flat section before pulling it.
• Emergency egress windows (Commuter and intercity rail): Double-deck and intercity railcars have specific windows framed in red or yellow rubber gaskets labeled Emergency Exit. Pull the red rubber gasket handle inward to rip the rubber seal out of the channel, then pull or push the entire framed glass pane inward or outward as indicated on the instruction decal. If using an emergency life hammer to break tempered safety glass, strike the bottom corner of the window firmly, never the bouncy center of the pane, and lay a thick jacket or blanket over the jagged bottom frame before climbing through.

3. Finding and using a subway tunnel "Blue Light Station"¶

In underground rapid-transit tunnels worldwide (particularly across North America, Europe, and Asia), you will see glowing blue lights mounted on the tunnel wall every 150 to 250 meters (500 to 800 feet) and at the ends of every station platform.

A Blue Light Station is your lifeline in a tunnel emergency. Directly beneath the blue light fixture you will find three critical tools:

1. An Emergency Telephone: A direct hardwired hotline handset or push-button intercom that rings straight to the Rail Control Center desk, automatically displaying your exact tunnel marker number to dispatchers even if cellular phone service is completely dead underground.
2. An Emergency Traction-Power Trip Switch ("Power Off Box"): A yellow or red pull-handle or break-glass push button that trips the high-voltage circuit breakers feeding the third rail in that tunnel zone, cutting off the 750-volt traction power immediately.
3. A Dry-Chemical Fire Extinguisher: Mounted in a bracket below the phone for suppressing small brake-shoe or trash fires.

Tunnel smoke dynamics: which direction should you walk?¶

During an underground train fire (such as an electrical arc fire beneath a car), the concrete subway tube acts like a horizontal chimney. Huge reversible tunnel ventilation fans mounted in shafts between stations are activated by transit control to push fresh air in from one station and exhaust smoke out the other end.

• Walk into the wind (against the airflow) away from the fire: Feel the direction of the air current on your face and watch which way the smoke is blowing. Whenever possible, evacuate away from the burning car into the incoming fresh air stream (upwind) rather than walking downwind in the same direction the smoke is traveling. Walking downwind means the toxic smoke plume moving at 3 to 5 meters per second (7 to 11 mph) will quickly overtake you in the tunnel before you reach the next station.
• Stay in the bottom 1 meter (3 feet) of air: Burning synthetic seat foam, wiring insulation, and fiberglass release superheated carbon monoxide, hydrogen cyanide, and hydrogen chloride gas that stratify along the top half of the tunnel ceiling. Bend low, breathe through a cloth dampened with water from your drinking bottle (never alcohol), and keep one hand lightly sliding along the raised walkway handrail so you do not lose your bearings if visibility drops to zero.
• Look for cross-passage fire doors in twin-bore tunnels: Modern deep-bore subways and underwater rail tunnels (such as the Channel Tunnel, Crossrail/Elizabeth Line, BART Transbay Tube, or modern Asian metros) are built as two separate parallel concrete tubes connected every 150 to 350 meters (500 to 1,150 feet) by pressurized, fire-rated steel cross-passage doors marked with bright green running-person lights. You do not need to walk kilometers to the next station; walk to the nearest green cross-passage door, push the panic bar to enter the pressurized safe corridor, and let the fire door close tightly behind you.

Special scenarios: underwater tubes, elevated bridges, and hazmat freight¶

1. Underwater subway tubes¶

If your subway train stops inside an underwater tunnel beneath a river or bay and water begins seeping or rushing in:

• Move immediately through the inter-car end doors toward the end of the train that is uphill (underwater tubes slope downward to a deep midpoint and then slope steeply upward toward both shorelines).
• Use the green-lit cross-passage doors to enter the central service gallery or adjacent tube, or walk briskly uphill along the raised emergency benchwall past the massive steel floodgates at the tunnel portal before they close.

2. Elevated rail viaducts and river bridges¶

• Extreme fall hazard: Elevated rail tracks often have open wooden ties with gaps looking straight down to the street 10 to 25 meters (33 to 82 feet) below, and many older elevated steel structures lack fenced guardrails along the outer edge or between tracks.
• Never climb out onto an elevated trestle unless flames are inside your car: Wait inside the railcar for fire department aerial ladder trucks or a rescue train pulled alongside on the adjacent track using a portable aluminum bridge board.

3. Mainline passenger trains near freight derailments¶

In North America and parts of Europe/Australia, passenger trains share rail corridors with heavy freight trains carrying pressurized tank cars of chlorine, anhydrous ammonia, vinyl chloride, or crude oil:

• If a collision involves freight tank cars and you see a vapor cloud, hear a loud hissing pressure-relief valve, or smell pungent chemical odors (like bleach, ammonia, rotten eggs, or sweet solvents), evacuate the train on the side away from the freight cars and walk rapidly upwind and uphill at least 800 meters (0.5 miles) away from the tracks. See our chemical spills and hazardous material leaks guide for full hazmat shelter and evacuation distances.

Контролна листа спремности путника у железници¶

Изградите ове навике без напора сваки пут када се укрцате у метро, ​​трамвај или приградски воз:

• Пребројите редове или стубове до најближег излаза и лоцирајте интерфон: Чим закорачите на вагон, баците поглед изнад врата да бисте уочили дугме Путнички интерфон за хитне случајеве и ручицу Отварање врата у нужди.
• Изаберите седишта окренута уназад или у средини у брзим возовима: Када се возите међуградском или приградском железницом, седење у средњим вагонима воза (уместо у првом вагону иза кабине или последњем вагону) и одабиром седишта окренутог уназад или седишта до прозора смањује повреде приликом судара.
• Чувајте тешке кофере на ниским подним полицама, никада изнад главе: Поставите тешке кофере на котрљају у полице за пртљаг у нивоу пода на крајевима вагона, а не на отворене полице изнад главе где постају смртоносне падајуће тежине током искакања из шина.
• Носите ципеле са затвореним прстима и равним ђоном током путовања на посао: Ходање 500 метара (1.640 стопа) преко назубљеног кречњачког баласта, масних дрвених веза и челичних шинских прекидача у тамним тунелима је подмукло у сандалама са отвореним прстима или високим потпетицама.
• Носите малу џепну батеријску лампу или држите телефон изнад 30% батерије: Наменско ЛЕД светло за привезак за кључеве вам омогућава да прегледате пругу испод врата воза за трећу шину, док вам обе руке буду слободне за безбедно спуштање.
