The document describes a student project to digitally implement signaling and track changing processes for a railway system. The objectives are to get experience with real-world digital logic design and implement automation to replace manual control. Key features include automated speed measurement, signaling and track changing with only brief train stops. The system uses combinational and sequential logic circuits at an affordable cost of 2500Tk to make railway transportation safer and more efficient.

3.  getting acquainted with real life digital logic
design and implementation practices
 digitally implementing the total signaling
process and track changing process in a
railway system
 employing combinational and sequential
logic circuitry to shape a purposeful gadget

5.  A lot of people depend on the
railway for transportation
 Railway is broadly used for
transporting goods also
 Technological implementation
in this field is essential
 Saving time is also another
primary concern
 Manual control of railway
system is hazardous & time-
consuming

6.  Compatible for the speed measurement of
trains.
 Provision for automated signaling.
 Ensures security by excluding manual
operation system.
 Ensures a smooth and safe track changing
process where only one train have to be
stopped only for some minutes.

8.  The primary cost incurred is 2500Tk.
 The application of digital technology in this
case is not very costly. So it is affordable.
