In pyrotechnics, in addition to fireworks and firecrackers, there are other products that are not used on holidays and to create spectacular effects. There are firecrackers needed in the railway industry.
Principle of use
Why do locomotives need dangerous things like firecrackers? These devices are called signal devices, and sometimes a lot depends on one such little thing. A signal railway firecracker is a small pyrotechnic type device. It is used in emergencies to give an audible signal to the engineer. The invention was created in the middle of the 19th century by Englishman Edward Cowper and has already saved hundreds of lives from unforeseen situations on the rails.
The train crew installs such firecrackers in case something happens on the neighboring section - the cargo being transported collapses and falls on the tracks, the train goes off the rails. Thus warns everyone about the situation.
The railroad is a serious object, in the operation of which there are strict rules. And ordinary people must also observe some rules. For example, it is strictly forbidden to pour salt on the rails.
