The Track Model

                                                                           The Train

                                                                       Track Switching

Problems Faced:

1) IR sensors are not reliable

-They stop working suddenly(Replace the IR sensor)

-It's difficult to debug which sensor is burnt out or stopped Working

-IR sensor senses daylight sometimes and provides wrong input to the MC

2)Railway Track is too large (portability is tough)

-Track Switching is difficult in the selected model

3)Keeping the model on the Card Board makes the model shaky 

-No firm Grip/ support for the model

-Wires keep getting disconnected cause of this

4)Soldering Problem

-Due to lot of connections to be made using wires to make the connections and solder them 

causes a lot of confusion and makes it difficult to debug.

5)Sound Sensor Problem

-Sound sensor keeps detecting unwanted sounds

-Defining it to work on a particular frequency is not reliable
