Prepare the required hardware components:

• ESP32 Development Board
• Railway Signal Modules
• Servo Motors or Track Switch Actuators
• Power Supply
• Connecting Wires
• Breadboard or PCB
• Optional Train Detection Sensors

Connect the railway signal modules and track switching mechanisms to the ESP32 GPIO pins. Ensure all components share a common ground connection and receive appropriate power.

Install the Arduino IDE and ESP32 board package. Upload the control firmware to the ESP32 using a USB connection. Verify that the board initializes correctly after programming.

Define the railway routes and signal states within the firmware. Assign specific GPIO pins to each signal and switching mechanism according to your layout requirements.

Test each signal and track switch separately to confirm proper operation. Check wiring connections and power levels if any component does not respond as expected.

Run multiple routing scenarios to ensure signals and track switches operate correctly. Verify that route selection updates the corresponding signal indications and switching positions.

Install the controller on the model railway layout and perform extended testing. The system is now ready for automated railway control and future feature expansion.
