1. Water Mist Fire Protection System – Enhancing Railway Passenger’s Safety
When constructing rail networks, platforms, railway engines and coaches, the most important aspect that
should be kept in mind is safety. Without any doubt, proper implementation of the safety measures
provides passengers the much needed assurance when they travel on the same route again and again.
When we talk about the threats or safety issues usually associated with railway systems, fire is perhaps
the most dangerous of them all. Every year, we come across horrifying news related to train accidents
and other mishaps in railway platforms, and a significant number of them happen when fire breaks out.
If we talk about freight and passenger trains, both of them come loaded with a number of fire risks, which
depends on the type of train as well as operating conditions. Nevertheless, it cannot be denied that the
situation gets much worse when fire breaks out in an underground passenger train. As a matter of fact,
the engines of trains usually have the traditional fire protection system. Yes, we are talking about the fixed
type of fire protection systems. On the other hand, passenger compartments as well as driver’s cabin
have usually relied on manual intervention, which involve portable fire extinguishers. Fortunately, things
have changed a lot, and certainly for the betterment of the railway sector.
These days, we can remain assured about our safety in trains and railway platforms due to a number of
reasons. Technology has become much better, and systems have turned out to be more effective and
efficient. One such fire protection system is the use of water mist to prevent the spread of fire and
extinguishing it as well. The combination of water and high pressure has turned out to be quite successful
as a fire protection system inside engines as well as passenger compartments. The concept behind the
system is about producing a vapor with heat absorbing property.
To be more specific, water mist can be defined as water droplet of size, even less than thousand microns,
and they are discharged from the nozzle with minimum operating pressure. However, the nozzle can be
used to control the pressure of the discharge of water through it, which is done using a nozzle with a

2. specific orifice size. As a matter of fact, mist created from certain volume of water can cover up more
surface area when compared to the same volume of water alone. And, when the same mist is turned into
steam, which happens too quickly, the steam formed absorbs a significant amount of heat from the
surroundings, which in turn bring down the temperature of the area. This is the reason why mist is so
effective in controlling fire and extinguishing it as well.
When fire breaks out in passenger compartments or coaches, without any doubt the firemen have to deal
with a huge area. However, the requirement of water can be minimized by the use of water mist fire
control system. And, with the passage of time, as technology would improve, new elements can be
incorporated into this system, which in turn will surely improve the safety level of the railway sector.
