INTRODUCTION
 The railway system is the most commonly used transportation
mode in India.
 Level crossings are managed by the gatekeeper and the
gatekeeper is instructed by the means of telephone at most of
the level cross from the control room.
 Delay in the opening and closing of the gate could lead to
railway accidents.
 To avoid the human errors that could occur during the
operation of gates, level crosses are controlled manually & the
concept of automation is introduced.
ABSTRACT
 The present work attempts to automate the opening and
closing of gates at a railway level crossing.
 The proposed system uses infrared sensors to detect the arrival
and departure of trains at the railway level crossing.
 The system uses two IR sensors to detect the arrival of the train
and a third IR sensor to detect the departure of the train.
SCHEMATIC DIAGRAM
INITIAL SIGNAL DISPLAY
 Signals SG1,SG2,SG3 and SG4 are placed near the gate each at
a specified distance. SG1 and SG4 are placed at 5Km
on either side of the gate whereas SG2 and SG3 are placed at
1Km from the gate.
 The road user signals are made GREEN so that they can freely
move through the gate buzzer is made OFF since there is no
approach of train and road users need not be warned.

TRAIN ARRIVAL DETECTION
 Train arrival is sensing is done by sensors R1 and R4
respectively considering the directions of train approach.
 When the train arrival is sensed by the sensors, the signal will
be YELLOW.
 After sensing next sensor the gate is closed and signal for road
users are made RED so that the vehicles cannot pass through
the gate.

TRAIN DEPARTURE DETECTION
 Train departure sensing is done by sensors R3 andR2
respectively considering the directions of train approach.
 When the train departure is sensed by the sensors, the gates are
opened.
 Once the gate is opened signal for road users are made GREEN
so that the vehicles can pass through the gate.
ARCHITECTURE DIAGRAM
APPLICATIONS
• Using the same principle as
that for gate control, we have
developed a concept of
automatic track switching.
• Considering a situation
wherein an express train and
a local train are travelling in
opposite directions on
the same track; Indicator
lights have been provided to
avoid collisions.
• Here the switching operation
is performed using a stepper
motor. In practical purposes
this can be achieved using
electromagnets
ADVANTAGES
 Management of road transport will be better.
 It will also minimize the risk of deaths in accident with trains.
 Reliable machine, which operates the railway gate even
without gatekeeper which makes it useful for operation at
unmanned crossings.
 Less traffic jam will be there.
 Management of Road transport will be better.
 Management of Road transport will be better.
CONCLUSION
 Avoids manual errors & provides ultimate safety to road users.
 Gatekeeper not necessary and automatic operation of the gate
through the motor.
 The mechanism works on a simple principle.
