ABSTRACT:
From past many years we have been using railway services. But according to railway statistics many people are dying and some are getting badly injured while shunting the trains from one platform to other. To overcome this human loss shunt safe instrument is used with hooter and LED lightening.
This instrument consists of IC 555 Timer for generating clock pulses/tone, IC 810 for audio amplifier to drive hooter, BC 547 to drive LED array.
This instrument can be operated manually or using a remote. It makes a huge sound with the help of hooter along with LED lightening so that people can be aware of the shunting of train.
