What is the purpose of railway detonators?
Detonators are used to stop trains in an emergency when other options fail. An explosive device that is akin to an anti-tank landmine, but just emits a loud sound, is partly responsible for your safe travel by train.
What is a track explosive?
Railway track explosives are small explosives which need to be strapped on the railway line for use. When the train wheel crushes it while passing over the explosive will explode with a loud report which is a signal to train drivers to stop the train.
What are railroad torpedoes?
A railroad torpedo is one of the oldest safety devices used by railroad companies.It is a small dynamite charge that’s wrapped in paper, with lead straps to hold it on a rail. When a locomotive’s wheel comes in contact with it, the weight of the engine sets off the charge and makes a loud sound that warns the engineer.
What are railway fog signals?
A railway fog signal is a small metal device containing a limited quantity of explosive. The device is placed on the running surface of a rail so that any rail-mounted vehicle passing over it would cause it to explode, and in so doing, alert the driver of the vehicle to a hazard on the line ahead.
What is the life of detonator?
Further, the normal shelf life of detonators manufactured during 2010 and thereafter shall be 5 years, reckoned from the year of its manufacture. It can, however, be extended further for a maximum of 3 more years, provided that detonators which are more than 5 years old are effective.

Are railway detonators still used?
The packaging will also be dangerous goods packaging approved by a competent authority. Railway track signals are sometimes referred to as ‘railway detonators’. This is a misnomer because railway track signals are not detonators and cannot be used as detonators.
How many types of detonators are there?
There are three categories of electrical detonators: instantaneous electrical detonators (IED), short period delay detonators (SPD) and long period delay detonators (LPD).
Do railroads still use torpedoes?
“Torpedoes” are Railroad signal devices which are strapped to the railhead and used to warn engineers and crews of a potential stop ahead. No longer used by the railroads, the best way to dispose of them is to safely discharge them.
What is the life of detonators?
The shelf life of detonators has been advised by the Ordnance Factory to be 5 years only, whereas earlier it used to be 7 years.
What is the safety range of detonator?
Safety Range – When detonators are being tested, no person should be allowed within a radius of 50 metres from the detonators to be exploded; the engine crew shall remain well within the cab.
What is the word for turning off a bomb?
Meaning of Defuse It means “to remove the fuse from (a mine, a bomb, etc.).” Its figurative meaning developed quickly after, and is now the meaning most of us are most likely to encounter: “to make less harmful, potent, or tense.”
What is the purpose of a train detonator?
These signal an emergency stop to the driver. Detonators are also used to protect engineering works where the line remains open. The controller of the possession will communicate with the operative with the detonators as to when to place them on the track, or lift them to allow a train through.
How far apart should detonators be placed on a railway line?
Defined by the Rule Book, when protecting a line for whatever reason (failed train, obstruction fouling the running lines), three detonators must be placed 20 yards apart. These signal an emergency stop to the driver.
What happened to Taiwan’s train detonators?
In November 2010, the Taiwan Railway Administration deployed 800 detonators for destruction on maintenance tracks. It received media attention, emitting sounds similar to the culturally significant firecrackers .
Why do detonators need to be replaced?
As with all explosives, detonators can become unstable over time and must, therefore, be replaced regularly. They are triggered by pressure, rather than impact. This makes them safe during transport, as they normally cannot detonate in a bag or storage container. This article contains too many or overly lengthy quotations for an encyclopedic entry.
