a swinging intersection point particularly
The invention related to/an improvement in Railway
Intersection Points by introducing a Swinging Nose. For the
movements of moving loads on Rails, whenever there is a
differential direction to the given path, an inter-section
Point with a flangeway clearance is employed for change of
path.
In the present system (Fig. 1), when a pair of Rails
branches out in two directions, one Rail from two pair of
branch lines has to cross each other. The intersection points
are made out from fixed components (Fig. 1) and have gaps
varying between 800 mm to 1000 mm depending on track angles
which varies from say 1 in 12 ( 4° 45' 49") to 1 in 8%
(6 421 35"). The moving load which is limited to an axle
load of 22.5 MT has to jump this gap causing high impact
load in the nose of the intersection point. In this process
the zone is subjected to fatigue resulting in wear and'
therefore are accident prone.
A disadvantage associated with the present system of
Railway intersection Points is that gaps varying between 800mm
to 1000mm restricts the speed of moving load. Superfast and
other fast trains while travelling non-stop has to slow down
at stations to cross several intersection points. This
considerably slows the train increasing travel time inspite of
very limited stops.

Another disadvantage with the the present
system of railway intersection points is that due to
high impact the zone is subject to fatigue resulting
in high wear and tear.
Yet another disadvantage with the present system
of railway intersection points is that due to wear and
tear and impact the gap may increase beyond safety limit
and may cause accident.
Still another disadvantage with the present system
of railway intersection points is that due to high impact
lot of noise is generated through the suspension to the
passenger compartment causing noise pollution.
To overcome this disadvantage/ there have been efforts
to modify the material of the nose to improve its load
and impact bearing capacity/ but despite improved wear
resistant properties/ which have been found to be effective
under normal travel conditions/ they have not responded
equally as well under conditions of impact. Also/ due to
the track geometry at the intersection point/ the speed
and axle load is restricted at the cross over and substantial
noise pollution is also generated.
To obviate the above disadvantages, the novel feature
of the invention has eliminated the gap or flange way
clearance making the cross over from one line to another
smooth and free of impact.

The object of this invention is to propose establishment
of continuous path in both the guide ways, reducing vibration
in moving loads resulting in reduction of maintenance and
increase of life for the intersection by elimintion of impact
forces.
Another object of this invention is to propose that due
to reduced vibration and impact, noise is greatly reduced
resulting in increased comfort and safety.
Still another object of this invention is the proposed
ability to go for higher speeds and axle loads across the
intersection.
Although the invention has been described in the context
of closed caption data, the invention is also applicable to
other forms of Rail structures with similar application with
certain modifications if required.
According to this invention there i.s provided a swinging
guidance of direction
intersection point for /change of travel path of a moving load
flexible
comprising a /vee nose of the intersection point formed by rails
and supported by guide structures characterized in that said
flexible
/Vee nose is hinged at one end (43} and is provided with an
expansion joint for angular movement of said Vee nose to rest
against either of the wing rail for change of the moving load
from one rail to another without any impact.
Further objects and advantages of this invention will be
more apparent from the ensuing description when read in
conjunction with the accompanying drawings wherein:
Fig. 1 shows the layout of the conventional intersection
point. The nose formed by wing rails 4 and 5 is fixed and forms
a gap with rails 1 and 2 at the nose which is around 3 inches.

Fig. 2 shows the layout of the present invention of the
intersection point, wherein the Vee nose 8 swings from one
direction to another and rest against the rail 10 and 11 and
leaves no gap for smooth travel without any impact enabling
longer life for the intersection point and enhanced load bearing
characteristics. In case of prior art the Vee-nose is fixed
hence leaves a gap of around 3" as seen from the prior art
drawing of figure 1. The Vee-nose comprising wing rails (4,5)
is permanently set between the rails (1,2) which resulted in
shorter life of the intersection point due to higher impacts
which resulted in the damage of the Vee-nose.
In accordance with this invention, the proposed swing nose
intersection point (8), the Vee, is hinged at end (13) and is
flexible. The Vee of the intersection point can be shifted from
one direction to another to redirect the travel path of a moving
load and to facilitate angular movement of the nose of the
intersection point, an expansion joint (12) has been introduced
which slides longtudinally. On both side of the Vee (8) are
located guide structures which during passage of a moving load
over the same, support the flexible Vee of the intersection
and are known as wings ( 10,11). The flexible Vee (8) formed
by.rails(4,5 ) and supported by guide structures (9) can be moved
to rest gainst either of the wings ( 10,11) for directing the
moving load in either travel direction. The profile of the wing

structures and the swinging Vee-nose (8) of the intersection
are so designed the proper transfer of load takes from one
structure to another for providing required rigidity and smoother
transition of the moving load from one rail (6) to another
without any impact. The assembly of rail (6) and the swinging
Vee—nose is supported by frame (7). This geometry enables the
guide ways of moving loads to have constant contact on both
sides, in difference to the normal arrangement (Fig. 1) where
there is a constant path- at the switch end whereas at the point
end the path is broken due to the flange way gap (3) at the
intersection resulting in impact on passage of moving loads.
The improvements highlighted above can also be achieved by a
stationary intersection with flexible wing structure and the
results are same as mentioned above.

relation to a non limiting embodiment and as defined
