Train drivers often neglect railway signals, which can lead to accidents, especially in foggy conditions. To address this problem, an automatic speed control system for trains was developed using a microcontroller. The system uses an infrared transmitter at the signal that communicates a code received by a receiver on the train. This allows the train's speed to be automatically controlled based on the signals to improve safety. The system is small, easy to operate remotely, inexpensive to manufacture, and flexible enough to be used in various applications including automation and remote areas.

2. Now a days there is a lot of problem with neglecting
railway signals by the driver in day today life. The driver
may neglect the train signals or it may not be clear due to
fog etc that reflects accidents of trains at different places.
We have taken the above problem for that we need one
solution that solution i.e. developed with automatic speed
control of train based on signals developed with
microcontroller. Here we have used an Infra Red (IR)
transmitter at the signal terminal We have established the
receiver part in the train that receives communication
code.

5. Advantages:
Small in size.
Easy to operate from a remote place.
Cost of manufacture is very less.
Flexibility of using in various applications.
Applications:
 After some small modifications made, the same kit can find
many applications.
Automation in industries ,house hold appliances etc
Also used in a remote areas where the facility of Cell network
is provided.
