Abstract - The primary goal of this research is to
highlight the factors that are used in metro trains in several
developed countries. Many metro lines have broken down in
recent days due to a variety of factors, including human
error. This can result in a variety of issues, including the loss
of human life, train delays, and other mechanical issues that
render the interior of a metro train unworkable, among
others. These issues can be quite harmful because they can
disrupt passengers' daily routines, and we all know how
valuable time is in our lives. As a result, we require a precise
and accurate transportation system for our convenience.
The automatic model train has been updated to overcome
this issue, and it now uses an ARM7 controller to operate
automatically. The 32-bit LPC-2148 microcontroller is
utilized as a CPU in this example to accomplish a variety of
tasks. One of these is for the train to come to a complete stop
when the IR sensor detects the platform and displays the
platform area on a three-segment display. When the train
detects an impediment, an obstacle detection unit is
activated, and the necessary information is shown on the
LCD display.
Key Words: ARM7, LPC2148, IR sensor, LCD display
1. INTRODUCTION
In this paper the problem with the railway analysis is to
find cracks in the structure. Trains build great
infrastructure and are an important means of
transportation in many lands. Improper train repairs can
lead to accidents. New railway technologies and better
safety measures are being introduced from time to time,
but accidents do occur. Thus, proper strategy is needed to
maintain and evaluate tracks. In this paper, the proposed
broken rail system automatically detects a faulty railway
line without human intervention. Benefits include lower
cost, lower power consumption and less analysis time,
with this proposed system. The location of the faulty
railway line can be easily identified and repaired
immediately to save many lives. Urban railway transit has
been getting more advanced, from trains to metro trains.
Driverless metro trains are a smart multi-passenger
solution that can work on its own. Driver-free technology
meets a number of objectives, including maximum volume,
speed and standardization, to reduce operating costs,
adaptability, flexibility; it complements the idea of a new
way of travel. In this project, the problem about a train
analysis is detection of cracks in the structure. Metro
comprises a large infrastructure and is an important mode
of transportation in many countries. The poor
maintenance of the railways can lead to accidents. New
technologies for railways and better safety measures are
introduced from time to time but still accidents do occur.
Thus, a proper strategy is required for maintenance and
inspection of tracks. In this project, the proposed broken
rail detection system automatically detects the faulty rail
track without any human intervention. Minimal cost, low
power usage, and quick analysis are just a few of the
benefits. With this proposed technique, the exact location
of the broken railway line might be swiftly found and
repaired, perhaps saving many lives. The planned
endeavor will look into a select high-risk regions and offer
measures to lower the incidence of events in order to
prevent mishaps like these. Human error or lacks of
manpower are the most common causes of accidents. Anti-
collision, automatic Track Fault Control, and tracking,
among other key issues, will be discussed. The two will
avoid colliding thanks to collision avoidance technology. If
the track fails, accidents caused by faulty tracks will be
averted. There are a few small features included, such as
platform directions and a crowd-based lighting system.
After an accident happens, the risk recognition feature will
enable immediate emergency help without the need for
human participation. Blocking sensors positioned close to
the railway will be used to prevent collisions. Obstacle
detection sensors using non-infrared LEDs and infrared
receivers.
2. METHODOLOGY
The proposed prototype accomplishes the task by
integrating the knowledge of embedded systems and
instrumentation systems. It decreases the need of manual
control as the whole system can be operated automatically.
The prototype is capable of detecting obstacles in front
of it and it also detects faults in the track through which
it commutes. There are also sensors attached to count
thenumber of passengers that enter and exit the train. A
sensor to sense the internal temperature of the train
bogey and to switch on the fan is also attached; a LDR is
also used to turnon or off the light in accordance with
the amount of light present in the bogey.

The train moves with the help of motor drivers, and we can
identify whether the driver is functioning or not using the
relay wherein we have used reverse motion the relay will
only blink when the motor stops running thus saving some
energy of the power supply. Person count will be functional
whenever a person passes through IR sensors, If the first IR
sensor is high and the second IR sensor is low, the person
is going in; if the second IR sensor is high and the first IR
sensor is low, the person is exiting. When both IR sensors
are high and the trains stop moving, the IR sensors that are
used to detect platforms operate, signaling that there is a
platform. The LCD will display the side on which both IR
sensors are high, indicating whether it is left or right. The
HCSR-04 obstacle detection sensor will assist in
determining whether or not there is a defect in the track
through which the train travels; if a fault is discovered, it
will be displayed on the LCD and the buzzer will buzz in
order to alert the passengers as well as the control station
thus ensuring the passengers safety. Each relay is used to
depict the functions of respective sensors such as the
temperature sensor, motor drivers and the LDR. The
temperature level is also displayed on the LCD and with a
rise in temperature the fans are switched on automatically
to comfort the passengers that are commuting. The LDR
observes the intensity of light if there is less light in the
train bogey it automatically turns on the light and switches
off the light if the condition is vice versa.
3. FLOWCHART
The following flowchart explains the about the complete
mechanism of the train. As the train starts to move the
motor drivers are set into action and the wheels start
running as soon as the sensors detect the station the
motors turn itself off and the passengers board the train.
This whole scenario if captured using the sensors at the
doors that count and display the number of passengers
that come in & go out. The displayalso indicates on which
side the platform is present and shows it on the display.
This flowchart indicates the functioning of obstacle
sensors when a train is in motion and if the obstacle
sensor detects any object in front of the train, the
wheels of the train will be stopped. If any obstacle is
not detected the train will be incontinuous motion.
4. RESULT
1) If the temperature in the train rises above 36C the
fan will be switched ON automatically and if the light

intensity of the train drops below 30% then the lights
will turn on automatically.
2) Two IR sensors placed on the right and left of the
train will help find the platform. The sensed platform
will be displayed on the LCD towards the side where the
platform is located, and the arrow will show direction
on the 3-segment display.

3) If there is an obstacle in front of the train the
ultrasonic sensor will detect it and the buzzer will
start buzzing and the message will be displayed
"OBSTACLE DETECTED" and the train will stop
moving.

4) The ultrasonic sensors are positioned right and
left in front of the train, which will help detect an
error while the train isin motion. If the left track is
faulty then the buzzer will start to buzz, and a
message will be displayed on LCD “TRACK FAULT
ON LEFT” and similarly if the right side of track is
faulty the LCD will display a message “TRACK FAULT
ONRIGHT” and the train will stop moving.

5. CONCLUSION
The train prototype presented in this paper has a new
approach for improving safety in railways. A common
unspoken conclusion, the benefit of such engineering
projects is that they expose students to a wide range of
development opportunities. Such initiatives may just be
a small part of what the future and technological
integration may entail.
FUTURE SCOPE
High-speed sensors, which allow for faster and more
efficient operation, can be added to this project to
improve it. The use of the GPS-GSM model will also give
us an upper hand in the near future. The existing system
can be made capable of switching tracks whenever it
detects a junction in the route it would be intelligent
enough to decide and follow the specified route. As
there will be more advancements in the technology
domain the system will be safer and will be smart
enough to provide clear and detailed decisions and
recommendations.
