Description of the Related Art
WWI Railroad carriages have been a -popular means of transportation for more
than a century. Most countries in the world posses a network of railway lines
crisscrossing
their lands. The mechanism of switching tracks of a railroad vehicle, is one
of the most
important aspects of railroad travel, as this is the core for enabling the
travel of a railroad
vehicle in a desired. direction.
[0004] Conventional rail switching systems use moving rails to switch
direction of
a. railroad vehicle. These mechanisms, known as rail switches, are slow to
reconfigure
from one position to the other. .fo accommodate for the low switching speed, a
large

distance is maintained between a. plurality of railroad vehicles travelling to
different
destinations. To compensate for the loss of throughput due to this separation,
railcars are
organized into long trains. The railcars have to be tough and heavy to have
the strength to
pull lengthy trains. Due to their massive weight, railroads cause an
extraordinary wear on
the tracks, resulting in expensive construction and maintenance costs,
Moreover,. most of
the wear and resulting maintenance cost is spent on the moving switches. A
lack of proper
maintenance often results in accidents.
[00051 To alleviate the above problems, there's a need for railcars to have
onboard
apparatus and mechanism to switch on otherwise passive rail tracks, currently
available
onboard switching mechanisms employ very complex design with complex
choreography
of the apparatus requiring expensive control systems. This makes the overall
system slow
and accident prone.
[0006] Hence, there is a need for an uncomplicated onboard mechanism for
enabling a railroad vehicle to switch tracks
(0007] The above-mentioned shortcomings, disadvantages and problems are
addressed herein and which will be understood by reading and studying the
following
specification.

points where two tracks intersect. The switching track comprises a separate
mono-rail or a
parallel-rail system. Apparatus onboard. the railroad vehicle can be
activated, to engage
with the switching track. or not depending on the intended destination of the
vehicle. Once
engaged, the switching track enacts the track changing mechanism for the
railroad vehicle
by smoothly separating the railroad vehicle from one running track and placing
it onto
another running track..
[0032] According to one embodiment herein, a mechanism for enabling a railroad
vehicle to switch tracks is provided. According to the present ynechanism, the
switching
track is elevated above the running tracks and above the railroad vehicle
running on it.
When the railroad vehicle approaches a switching point and intends to switch
tracks, a one
or more switching wheels in the railroad vehicle are activated to engage with
the
switching track. When the switching track and switching wheels are engaged,
the railroad
vehicle becomes suspended vertically down from the switching track. The
switching track
is designed to guide the railroad vehicle onto a second running track and
place the railroad
vehicle on the second running track. When the railroad -vehicle approaches a
switching
point and intends to not switch tracks, the switching wheels are not activated
and the
railroad vehicle continues to travel on the same running track.
[0033] According to one embodiment herein, yet another mechanism for enabling
a railroad vehicle to switch tracks is provided. According to the present
mechanism. the
switching track is at the same- level as. the running track. The gauge of the
switching track
and the running track are different. The switching track can be. narrower or
broader than

diverge beyond the
switching point. At the merging switching point, the switching track and
running track, run
parallel to each other for some distance beyond. the switching point. When the
railroad
vehicle approaches a switching point and intends to switch tracks, onboard
apparatus
including a one or more switching wheels is activated in the railroad vehicle.
The
switching wheels, when activated, are designed to get engaged to the switching
track.
When the switching track and switching wheels are engaged, the railroad
vehicle, is
designed to disengage the primary running wheels .from the running track. The
switching
track is designed to guide the railroad vehicle to a second running track and
place the
railroad vehicle on the second running track. When the railroad vehicle
approaches a
switching point and intends to not switch tracks, the switching wheels are not
activated
and the railroad vehicle continues to travel on the same running track,

a railroad vehicle to switch tracks is provided. According to the present
medhanism, the
switching track starts at the same level as.-the running track and slowly
rises to a height
where vehicles running on the running track can pass under the switching
track. The gauge
of-the-switching track-is broader than the running track. At the bifurcation
switching .point,
the switching track and The running track run in parallel for some distance
before the
switching point and diverge beyond the switching point. At the merging
switching point,
the switching track and running track run parallel to each other for some
