1. IntroductionThe Dedicated Freight Corridor (DFC) Project:

Ministry of Railways (MOR), Government of India hasplanned to construct Dedicated High Axle

Load Freight Corridor covering about 3363 kms on two corridors, Eastern Corridor from

Ludhiana (Sahnewal) to Dankuni and Western Corridor from Jawaharlal Nehru Port, Mumbai

to Tughlakabad/ Dadri near Delhi along with inter-linking of the two corridors at Dadri.

Dedicated Freight Corridor Corporation of India Ltd (DFCC), a public sector company has been

set up under the Indian Companies Act 1956 for implementation of Dedicated Freight Corridor

Project.

Eastern DFC Route will be approximately 1847 Km long from Dankuni to Ludhiana via

MughalsaraiAllahabadKanpurTundlaAligarh and Khurja. Proposed alignment of DFChas been generally kept parallel to existing Indian Railway line except provision of

detours at locations bypassing the major cities/towns.

MughalsaraiNew Bhaupur Section (Double line 402 Kms) Phase 2 of the Eastern Dedicated

Freight Corridor project starts from near Howrah end of existing Mughalsarai station of Indian

Railways (between Mughalsarai-Ganjkhwaja stations) to New Bhaupur station (situated near

the existing Bhaupur station of Indian Railways) via Mirzapur - Allahabad - Fatehpur - Prempur -

Kanpur. Approximate total length in detour is 130 Kms.

This Phase 2 of the total project is divided into 2 contracts i.e. Contract Slice no. 201 and

Contract Slice no. 202. There may be possibilities of awarding both contracts to a singlecontractor or separate contractors for individual contracts depending upon the evaluation of

the technical and commercial bids.

2. DFCC Requirement on RailsThe total track length for the Phase 2 i.e from Mughalsarai to New Bhaupur is approx. 830 track

kms.

The total quantity of rail required considering 120MT/km is 830km*120MT/km= 99,600MT

As per DFCCIL (APL-1 from Bhaupur to Khurja Ph 1), specification of the Rails is as follows:

3.Available manufacturersThe List of available manufacturers for the Grade 880 UIC 60kg are as follows:

Domestic:

Steel Authority of India Limited Jindal Steel and Power Limited

International

Sr No. Company Name Country

1 Arcelor Mittal Luxemberg, Poland, Germany

2 Nippon Steel Japan

3 Voestalpine Schienen GmbH Austria

4 Tata Corus France

Apart from the above there are various manufacturers from China and Korea that manufacture

rails of 880 Grade.

4. Options available for LengthThe rails that are manufactured can be obtained in various lengths.

The standard lengths that have been indicated in IRS T-12 2009 on the length of the rail procured are

as follows:


6/17

Rails of lengths greater than 26m i.e 130m or 260m are also possible. But as of now in india, SAIL

hasnt supplied rails greater than 26m length directly from the manufacturing plant.

So considering that the manufacturer can provide the rails in lengths greater than 26m, the options

that are available with us are:

13m 26m 130m 260m

5. Transportation of RailsThe transportation of rails from the source location to the site can be done in two ways:

I. Transportation by RoadII. Transportation by Rail

I. Transportation by RoadOne of the modes of transport of the rails from the source i.e the steel plant to the site location

can be transportation by road.

The vehicle that will be used for the transportation by road shall be Trailers.

The major constraint in transportation of Rails by road has been the length of the Rails.

13m rails (42ft) can be transported easily transported on trailers of 50ft flat bed. This is astandard trailer and is easily available. These are generally used in transportation of various

other materials other than Rails like Steel rolled sections, steel pipes, steel channels etc.

.

According to IRC-SP-41, the minimum dimensions for the movement of the vehicle are as

follows:

Figure 1: Minimum turning path for a Trailor according to IRC SP-41

26m rails (85ft) can also be transported on trailers but this will require special type of trailerswith extended beds and has lot of problems during the transit operations.

Rail lifting and handling:

As per DFCCIL (APL-1) document, following specification on the handling of rails has been

indicated:


8/17




Page 8of 17

The high carbon and alloy steel used in the manufacture of rails renders the rails very

sensitive to shock or impact loading, bruising, notching or marking on the surface, and the

point or line loading.

This is especially true in handling the longer rails being produced in the rail mills welding

plants. The staff handling such rails are required to:

o Use strings made of flat link chains or holders of specific material.The attachments can be classified into two types:

Single rail lifting Multi rail lifting

There are various suppliers of these lifting attachments such as:

Geismar

Engcon

Camlock etc.

Single rail Lifting:

Page 10of 17

o Use of magnetic devices is preferable.o Use multipoint slinging for lifting of rails. As per the Flash Butt Welding manualby

RDSO the recommended lifting points are as follows:

o Stack the rails on firm, level and well drained ground.

o Stack subsequent layers on the uniformly placed spacerso Place rails of shorter length in upper layerso Handle rail gently without sudden impact.o Use protective clothing, gloves and helmet of distinctive colour

Location of Unloading:

Unloading of the rails can be done at two locations:

At the depot location At intermediate locations such as level crossing, junction stations, crossing stations etc.


11/17




Page 11of 17

At the depot location:Unloading the rails at the depot location shall involve extra expenditure on transporting the

rails again from the depot to the site location and hence this option can be avoided.

At intermediate locations such as level crossing, junction stations, crossing stations etc.:One of the best locations for unloading the rails shall be the intermediate level crossing,

junction stations, crossing stations locations where there will be enough space to unload the

rails and stack them in layers.

The unloaded rails stacked on the cess of the formations at these locations shall be lifted

and placed on the formation using a using a 360deg excavator with a special lifting

attachment as mentioned above.

After the rails are placed on the formation, the rails are then welded using a mobile flash

butt welding plant.


12/17




Page 12of 17

After the rails are welded, these are then dragged on rollers using a tractor or vehicle of

similar power, all along the alignment.

Welding is done in lengths of 500m as lengths more than 500m will be difficult to drag.

II. Transportation by RailThe most economical way for the transportation of rails from the steel plant / the rail manufacturing

unit to the site location shall be by rail.

The scope of transportation of rails by Indian Railway route shall be in the scope of the

manufacturer/supplier.

The rails can be obtained by Indian Railway network from the following domestic vendors:

Steel Authority of India Limited Jindal Steel And Power Limited

Rails of all lengths can be obtained on Railway Rakes i.e. 13m, 26m, 130m and 260m.

The rails of 13m lengths can be transported easily using the standard flat wagons i.e. BFR or the

BRNA wagons.

As per the discussion held with Mr. Bajaj of Jindal Steel and Power Limited, the rails of length greater

than 13m needs to be transported using special flat wagons known as the BLL flat wagons.

For the carriage of 260m long panels, JSPL has submitted the request for allotment of wagons to

Indian Railways.

In these flat wagons, at the coupler location there are these flat plates which have the roller

attachment on which the rails will be mounted.

As per the information obtained from JSPL, one rake of BLL wagons i.e. 40 no.s of wagons can carry

260m rail panels for quantity equivalent to 17kms of Track length.

Handling of rails of 260m while unloading of rail panels:

The loading arrangement of the rails for the 260m long rails shall be under the scope of the

manufacturer/supplier.

The unloading of the rails however will be under our scope and the necessary arrangement

for the unloading process shall be arranged at the unloading point.
