Background of Invention
There are many problems in our daily life. Out of these, science has made it possible
to solve many of them. Still there are other problems yet to solve.
In railways there is burning problem of sanitation of toilet in train coaches and
passenger has to suffer a lot of agonies during their train journey. It is very difficult
to travel in a train for long time without using a toilet. Often the toilet of the coaches
are very dirty and unhygienic . Sometimes it is seen that after passing a watering
station water is not available in all the coaches. So passengers are forced to travel in a
unclean and dirty situation. It becomes a big problem mainly for patients and
children. The passengers who are going in a long journey this problem of toilets
become very difficult for them. Now-a-days, trains are very long in length and stop
after a long interval of time. So one can't take advantage of facility available on the
spot. For this, it is very essential to supply water in the toilets of every coach.
PROBLEM FOR MAINTENANCE IN EXISTING SYSTEM
Railways department nominates certain stations for looking water availability and
stoppage time as a watering point for train. Trains are watered at these stations. The
water is filled in the toilet tank by fixing a flexible hose-pipe from the opposite side of
the platform at least in two places of every coach. Supply pipe line of water generally
is located between the two running lines and above a drain. There are no proper path
ways to operate this type of work, sometimes there are no lights also . In this
situation a man can pour water in two or three coaches within stipulated stoppage
time. Sometimes working out of hose - pipe creates problem for watering and
wastage of water is seen. The situation become so bad sometime that passengers get
irritated and railways lose their goodwill. Though water is available in the station but
coaches can't get the supply of water.

Detailed Description of the Invention
The system facilitates supply of water uniformly to every coach of the train in a very
short time with a lesser manpower. The system saves wastage of water which is so
precious. ( See Diagram)
The main pipe (MP) of a coach will run over all the coaches of the train and about 400
mm will be projected out of each side of the each coach. The main pipe (MP) should
be tightened with the ceiling of all coaches of the train.
From the projected portion of the main pipe a high pressure flexible hose (HPFH)
should be attached with adjacent coach's projected portion of a main pipe (MP) .
Like this, all the coaches of the train will be connected together with high pressure
flexible hose (HPFH).
Both the ends of the train's main pipe are required to be blocked with the plugs.
In every coach four feeder .pipes to be located in the existing position at the corner of
the coaches. The lower end of the feeder pipe below the coach corner is fixed with
quick cuppler (1st part) so that it can attached easily, lightly and leak proof.
Other end of the filler pipe to be connected with main pipe from both the sides in both
ends of coach with the help of the reducing cross socket and through a spring loaded
one way valve, it will allow to flow water from feeder pipe to main pipe only.
One tank filling pipe should be connected with main pipe with a T shaped
socket just above the toilet tank and other end of the tank filling pipe should be
connected with toilet tank through one floating ball type stop valve, so that whenever
toilet tank filled up desirable level of water it stop further water flow to the particular
In the tank filling pipe between main pipe joint and floating value a separate
valve called flushing valve is to be fixed to facilitate automatic flushing of toilet floor.
The flushing valve will allow to flow water through it for 30 only just while the tank
will fill up. It should be operated with floating type ball valve movement . The
flushing valve will allow to flow water into the flushing pipe arrangement in which a
number of jet system at toilet floor level will be operated from all directions is located
in the lower portion of the toilet wall through which water force will come to spray in
the toilet floor so that the toilet floor may wash out automatically just after filling of
the toilet tank. Main pipe of the coaches are interconnected of the full train will
operate one by one.
WATER SUPPLY SYSTEM IN THE PLATFORM
In the existing system there are several from the opposite side of the platform. In the
existing system all the individual toilet tanks required to fill up by fixing a hose pipe
in the system.
The system I want to develop in which the main hydrain pipe should be
brought to platform side instead of opposite side.
In this system main hydrain pipe will run through the platform at about 300
mm below the platform and at about 300 mm inside the platform from its edge
parallel to the railway track. A 150 mm dia pipe is required to use in which there will
be a constant supply of water with a pressure of 2.5 kg - 3 kg per cm2 . Constantly
available from the main source.
Considering the regular stopping position of train engine one box type opening
should be provided on the platform above the main hydrain pipe at about a distance of
3 coaches length and nearer to the joining point of coach no. 3 and 4 and the next
other boxes to be located 6 coach length apart.
Within the each box on the platform 2 wheel valves are require to connect
with main hydrain pipe facing towards track. Each of the wheel valve to be connected
with flexible of require size hose. Other end of the hose is fitted with a part of quick
cuppling to facilitated quick attachment / detachment of hose with feeder pipe quick
cuppling portion. Keeping the whole system i.e., wheel valve, hose, quick cuppling
etc it the box it should be closed with a heavy lid. The upper portion of the lid
requires to levelled with the platform so that passenger can easily walk on it.
WORKING OF THE SYSTEM
The system is designed to fill up toilet tank easily, quickly and evenly in
watering station and for automatic flushing of toilet. Just on arrival of trains two men
start working from forward and backward side of the train.
First of all they open the lid of the box after drawing out flexible hoses from
the box they connect the quick cupplers with the filler pipe quick cuppler and open
both the wheel valves to allow flow of water and after closing the lid again they will
move for next box situated 6 coaches away and repeat their job again. After fixing up
the hose they will come to the first position care whether toilet flush out or not. Just
after flushing out of maximum toilets they will close the wheel valve remove hoses
from the quick cuppling connection keeping the whole system in the box they will
finally close the lid again and repeat the job in the next box again to complete their
work for a particular train in a particular time.
The water supply through hydrain pipe will reach to main pipe through wheel
valve, hose, filler pipe, one way valve. From main pipe (MP) water will flow through
feeder pipe and floating ball valve to the toilet tank at different location in different
coach (As main pipe is connected together with flexible hose).
Whenever a particular tank of a particular coach will filled up immediately the
flushing valve will start working for 30 sec and water will flow through the flushing
pipe and the ball valve will close the opening of the tank of the train filled up and
washed up the water pressure in side the main pipe will come equal to main hydrain
pipe water pressure and one way valve close its path automatically and compressed
water will lock inside the main pipe.
Whenever any passenger start using water in a toilet and the water level of
toilet tank comes down which will give further path to the ball valve to flow water
from main pipe reserve water into the particular toilet tank. In this manner additional
water supplied to these tanks which are having more consumption.
