Indian Railways is the life-line of nation providing transportation facility over the length and breadth of country. It’s vision is to provide efficient, affordable, customer-focused, environmentally sustainable integrated transportation solutions and to be the vehicle of inclusive growth, connecting regions, communities, ports and centers of industry, commerce, tourism and pilgrimage across the country.
Civil Engineering infrastructure is the largest static infrastructure of Indian Railways comprising of track, bridges, land, etc. Management of this huge infrastructure has to be done in accordance with the organization’s vision. Civil engineering department of Indian Railways manages and maintains all these infrastructures. Further, it has key role in the area of infrastructure development, technological leap in various fields, high speed travel and development of world class stations.
Track and Bridges
As on 31.03.2017, the route length of Indian Railways covered 67,368 kms with running track length of 93,902 kms. The total trackage including yards, sidings etc. stood at 1,21,407 kms. The table below shows the changing size of IR's electrified rail network over the years.
|Year||Route kms.||Running Track kms.||Total Track kms.#|
State-wise Route Kms/ Running Kms./ Total Track Kms.:
Followings table shows Route Kms., Running Track Kms. & Total Track Kms. of railway lines across various States/Union Territories at the end of 2016-17.
|State/Union Territory||Route kms.||Running Track kms.||Total Track kms.|
|Jammu & Kashmir||298||366||491|
Broad gauge, though forming 91.56% of the route, generated 100% of the freight output (NTKms) and 99.22% of the passenger output (PKms).
Route length as on 31.03.2017 on each gauge, indicating double/multiple line, single line and electrified route, is given below:
|Gauge||Single line||Double/multiple line||Grand Total|
|Electrified||Non electrified||Total||Electrified||Non electrified||Total|
|Broad (1676 mm)||7,190.49||32,468.77||39,659.26||18,176.79||3,844.18||22,020.97||61,680.23|
|Metre (1000 mm)||0||3,479.13||3,479.13||0||0||0||3,479.13|
|Narrow (762 mm/610 mm)||0||2,208.46||2,208.46||0||0||0||2,208.46|
Almost all Double/Multiple Track sections and Electrified Routes are Broad Gauge. Meter and Narrow Gauges are mostly single line and non-electrified. Between 1950-51 and 2016-17, traffic density (million GTKms. Per running track Km.) increased from 4.29 to 22.00 on BG.
As on 01.04.2017, IR has 1,44,698 bridges out of which 680 are important, 11,915 are major and 1,32,103 are minor bridges. In the year 2016-17, 753 bridges were strengthened/ rehabilitated/rebuilt.
Road Over/Under Bridges:
To improve safety of train operation and reduce inconvenience to road users, level crossings are being replaced by Road Over/Under Bridges/Subways (ROBs/RUBs) in a phased manner based on the quantum of traffic.
There are 2207 of sanctioned works of ROBs/RUBs appearing in Pink Book 2017-18 which contains 1670 ROBs and 6213 RUBs/Subways. These are at various stages of planning, estimation and execution.
During the year 2016-17, 171 ROBs and 1183 RUBs/subways have been constructed under cost sharing, railway cost/accommodation works, Deposit/BOT term and by NHAI over Indian Railway.
Level crossing are meant to facilitate the smooth running of traffic in regulated manner governed by specific rules & conditions, Status of level crossings on IR as on 01.04.2017 is as under:
|Total number of level crossings||27,181|
|Number of manned level crossings||19,480||(72%)|
|Number of unmanned level crossings||7,701||(28%)|
Indian Railway has decided to progressively eliminate the level crossings for the safety of road users and train passengers. During the year 2016-17, 1503 Nos. of unmanned level crossings and 509 Nos. of manned level crossing have been eliminated.
As on 31.03.2017 Indian Railway (IR) owns about 4.76 lakh hectares of land. About 90% of this land is under Railway’ operational and allied usages such as laying of new lines, doubling, gauge conversions, track, station, workshop, staff colonies etc. The break-up of the land is as under:
(in lakh hectares)
|Tracks and structures including Stations, colonies, etc.||3.66|
|'Grow More Food' scheme||0.03|
|Other uses like pisiculture||0.09|
