The Udhampur-Srinagar-Baramulla Railway Link Project connects the Jammu and Kashmir region to the rest of India via rail. It is 345 km long and divided into three sections. The project aims to reduce travel time and provide an all-weather transportation system for socio-economic development. It faces challenges due to operating in earthquake and extreme temperature zones. Major obstacles include the Chenab Bridge, which will be the world's highest rail bridge, and the Pir Panjal Tunnel, which will be India's longest tunnel. The project involves complex engineering due to the difficult terrain and security issues in the region.
2. Introduction
• Jammu and Kashmir has limited surface accessibility to the rest of the
country.
• Providing a reliable transport system crossing major earthquake zones
which is subjected to extreme temperatures making it the most difficult
railway project taken in India.
• Already existing road link is 350 km long – NH 1 A.
• Rail link : 345 km in length running from Jammu to Baramulla.
• Declared as a Project of national importance in 2002.
• Facing many problems in completion and the project estimated cost is escalated
to many folds.
3. Objective
s
• Reducing the travel time to
various destinations in the
valley considerably.
• All weather transportation
system that could function in
adverse weather conditions.
• Socio-economic development
of the state.
• Employment Generation
5. The project is divided into three sections:
• Leg 0 – It extends 53 km from Jammu to
Udhampur which was completed in April
2005.
• Leg 1 – It extends 25 km from Udhampur to
Katra which is under construction.
• Leg 2 – extending 129 km from Katra to
Qazigund which is under construction.
Execution was started in november 2002.
• Leg 3 – extending 119 km from Qazigund to
Baramulla which was completed in October
2009.
Project Breakdown
6. Project Management
The project is being implemented by three principal agencies:
• Northern Railway Construction Organisation (NRCO)
• Konkan Railway Construction Limited (KRCL)
• IRCON International Limited
7. Most Challenging Part of the Project
Chenab Bridge.
Pir Panjal Tunnel.
Anjikhad Bridge.
8. Chenab Bridge.
• The rail height from the river bed will be 359 m which will
make it the tallest rail bridge in the world.
• The main arch will have a span of 465 m which gives
another distinction to this bridge being the longest single
span railway arch bridge in the world.
• A very elaborate procedure has been followed as there is no
Indian Code for designing mega structures.
• Since the area is prone to terrorist attacks, the blast load has
been taken into consideration for design.
9. Pir Panjal Tunnel (T-80)
It is 11 km long aligned in almost N-S
direction.
The method for tunnelling used is NATM
(New Austrian Tunneling Method).
The tunnel is the longest in India and
the third longest in Asia.
It is lower than the existing road tunnel
and will be much less vulnerable to
snow.
Problems in using TBM (Tunnel Boring
Machine)
Portal areas are situated in fluvio-glacial
sediments, i.e. soft ground.
No bidder was prepared to mobilize two
TBMs.
Fault zones hindered the use of TBM.
10. Conclusion
USBRL project was proposed to provide
an adequate transport system which will
be efficient in all the weather and to
quash the travel time to cover the
distance between Kashmir valley and rest
of the country.
Most difficult projects , sensitive region
with very weak support for logistics.
National importance and related
difficulties associated with project,
proper planning before execution is a
must condition.
12. Introduction
Gauge is defined as the minimum distance
between inner face two rails. Indian Railways
follows this standard practice and the gauge is
measured as the clear minimum distance
between the running faces of the two rails as
shown in Fig.2.1
13. TYPES OF GAUGES IN INDIA
The different gauges in India
are of the following these
types :-
1. Broad gauge (1676),
2. Meter gauge (1000),
3. Narrow gauge (762 mm &
610 mm),
4. Standard Gauge (1432mm)
