The alarm chain inside a train is an important safety feature that allows passengers to stop a moving train during a genuine emergency. However, Indian Railways has repeatedly urged passengers not to misuse it. The Railways has also flagged cases where people board trains to see off family or friends but fail to get down before the train starts moving, sometimes leading to an unnecessary alarm chain pull and delays. Want to know when to use the alarm chain and what the penalty is if we misuse it? Read on.
How Does The Alarm Chain Stop A Train?
Talking to The Indian Express, Dr Shivam Sharma, Chief Public Relations Officer (CPRO), North Central Railway, explained that the alarm chain is connected to the train’s main brake pipe through a vent valve. Normally, the brake pipe maintains an air pressure of around 5 kg per sq cm. When the chain is pulled, the valve opens and air escapes, causing the brake pressure to drop and slowing the train. The change in pressure is visible to the loco pilot on the pressure gauge, allowing the train to be brought to a stop.
Three horn sounds alert the guard and security personnel that the alarm chain has been pulled. A loud hissing sound from the escaping air can also help staff identify the affected coach. Once the reason is checked and the chain is manually reset, the train can resume its journey.

When Can Passengers Pull The Alarm Chain?
The chain should only be used in a genuine emergency involving passenger safety. This may include a serious medical emergency, a passenger falling or slipping from the train, a fire, or a serious criminal or security incident. The emergency must be serious enough to require the train to stop immediately.
People often mistake missing their station or boarding the wrong train as valid reasons to pull the alarm chain. However, as per the portal, neither situation is considered a valid reason. Passengers should get down at the next station and make alternative travel arrangements instead of stopping the entire train.
What Is The Penalty?
Unnecessary alarm chain pulling is punishable under Section 141 of the Railways Act, 1989. A person can face imprisonment of up to one year, a fine of up to ₹1,000, or both. The law also provides for a minimum fine of ₹500 for a first offence in specified circumstances.
