Shimla railway Station Building is another Heritage structure of special significance. Visitors feel happy to arrive and alight at one of India's significant hill tourist destinations and capital city of Himachal Pradesh, Shimla. The Shimla railway station was constructed in 1903 under the supervision of then 'Chief Engineer and Agent of KSR' Mr. H.S. Herington. This building was modified in 1921 with a new double storey design for the offices (Station Master, staff and control), accident relief arrangement, waiting room, shelter, shed for handcarts and a horse stand. The walls of the building were constructed with brick masonry in lime mortar plastered from outside as well as inside. Later on, in 1944, the platform shelter collapsed due to heavy snowfall, and consequently a new shed over the station building and platform was constructed under the supervision of Mr. M.W. Bouldwin, the then Engineer of KSR. At the same time, additional offices were also constructed on the first floor. Over the years, many development work have been undertaken for Shimla Railway station. These include end-to-end platform shelter, tourist information office, railway telephone exchange, ticketing office, computerized reservation office, ten retiring rooms and a spacious waiting hall that offers panoramic view of the valley to the visitors.
