Himachal Pradesh do not have a well developed rail network likes its neighbouring states Punjab and Haryana. This can be attributed to its mountain terrains which are still new in terms of geographical timeline and still being shaped by the works of earth. Having said that, there are one broad guage and two narrow gauge railway lines in the hilly state.

1. The Kalka Shimla Railway Line
2. The Kalka Valley Line
3. Nangal Dam to Una Broad Guage

The Kalka Shimla Railway
The Kalka Shimla Railway is a 96 km long narrow guage line that traverses through the picturesque hilly regions of Himachal Pradesh between Kalka and Shimla.
