Indian Railways Explains Alarm Chain Rules, Penalties and Emergencies
An alarm chain on a train is meant for serious emergencies.
When someone pulls it, air escapes from the train’s brake system.
The lower air pressure tells the loco pilot to slow and stop the train.
A fast-moving train may need time to stop safely.
Railway workers then check what happened and reset the chain.
The chain can be used for problems such as a fire, a serious medical emergency or someone falling from the train.
It should not be pulled because someone missed a station or boarded the wrong train.
Unnecessary stops can delay many passengers and other trains.
People who misuse the chain may face a fine or imprisonment.
Pulling the alarm chain vents air from the train’s brake pipe, reducing pressure and slowing the train.
Railway staff investigate the stoppage, reset the chain and allow the train to resume when appropriate.
The chain should be used only for serious emergencies, such as a medical crisis, fire, passenger fall or security incident.
Missing a station or boarding the wrong train is not a valid reason to pull the chain.
Unnecessary use is punishable under Section 141 of the Railways Act, 1989, with fines or imprisonment.

“A strong hissing sound caused by the escaping air can also be heard from the coach where the alarm chain was pulled. This helps railway staff identify the affected coach. Once the reason for the alarm chain pulling is checked and the chain is manually reset, the train can resume its journey.”

“If someone misses their station or realises that they are travelling on the wrong train, they should get down at the next station and make alternative travel arrangements.”
