I, student “Chandravati Group Of Institution ,Bharatpur “would like to pay my heart felt thanks to the Indian Railway for providing an immense knowledge and co-operation. I would like to express my gratitude to “ Mr. Anamol kumar ” (j.en) DRM KOTA for their corperation and

Guidance during the training.

Indian Railway is the world’s fourth largest commercial, by number of employees with over 1.4 million employees. Railways were first introduced in India in 1853. Indian Railways operates both long distance and suburban rail systems on a multi-gauge network of board meter and narrow gauges.

From 20th December 2010, the railways had developed a 5 digit numbering system. This need is required because IR runs 10,000 trains daily

After many decades of satisfactory performance, the steam

engines were to give way to more modern locomotives.

The year 1881 saw the birth of the first electric Railway run

by a German Engineer Werner Van Siemens using both the

rails to carry the current. Finding this a little too dangerous,

Siemens soon adopted the overhead electric wires.

Electric locomotives today raun on Rail roads in many

countries.

In platform lightning two type sensors are used:-

1) Lightning sensor

2) Train scheduler sensors

1 All the lightning system is replace by sensor base lightning system.

2 solar panels lightning system are used.

3 All bulbs are replaced by CFL.

4.Now a days we are using led light in place of CFL.
