Introduction of DFC Mughalsarai unit:

The CPM/MGS office is situated at Varanasi and is presently headed by CPM/ALD(E).

Initially the Jurisdiction of the MGS unit is 120 Km, now revised to 122 Km after adding 2 more Kms from the Sone bridge towards HWH end.

The zero chainage of the MGS unit starts from the center line of the first abutment (HWH end ) of the SONE Bridge.

One field unit is at Mohania (nearest Rly station is Bhabhua road station) where in one APM(Civil) and one APM(El) are posted. They are assisted by Executives. The office accommodation at this field unit has been provided by the M/s L&T to both DFC and PMC on contract obligation.

Second field unit is at Sasaram (SSM) wherein One APM(El), One APM(S&T) and One Executive (El) are posted. This office is arranged by the DFC itself on rental basis.

One Executive Civil is posted at Sonnagar, exclusive for the SONE bridge construction work. APM/EL/AII & ABR on 4-5.9.2014

Civil building and track work:

The work is being executed by the Joint venture of M/s C&C and M/s B Sinaiya with M/s Ferrovia as subcontractor for track work. The work is awarded for 108 Km section between MGS-SEB. This includes the 66 Km high priority stretch between Durgawati- Karwandia targeted for completion in Dec’2014 . The DFC stations are planned at New Durgawati (JS), Kudra (CS) and New Karwandia (JS) . The DFC staff quarters will be constructed at Sasaram. The temporary OCC (Operation Control Center) will be at DRM control office at Varanasi. As per schedule, the IR junction point will be at IR Durgawati station and IR Karwandia station. At the IR junction point , all the Civil, S&T work will be carried out by the Indian Railway and the SWR will also required to be modified accordingly. The track is parallel to the existing railway . At various places the land is acquired by the DFC for track building and on service road account.

Electrical and Signaling & Telecom work:

The work is being executed as Combined System Package by M/s L&T for the 66 Km high priority stretch between Durgawati- Karwandia and is targeted for completion in Dec’2014 . The work is in full swing. For electrical work the galvanized mast of B-175,B-200 & B-250 of length 9.5 Meters are being used. Contact wire of 150 Sq.mm and catenary wire of 130 sq. mm against 107 Sq.mm and 65 sq.mm used in IR are scheduled respectively. Mast Foundation of type B-8, B-10 and B-12 are being done. The scope of Electrical work includes erection of the 12 Kms long 132 Kv transmission line from 220Kv/132Kv Dehri on Sone GSS of BSPTCL to the DFC TSS at New Karwandia station . The DFC TSS will operate at 132Kv/25 Kv level. The S&T works is also going on. At some places the LC lifting barrier are being shifted beyond the DFC ROW. M/s L&T have made a combined full fledge stores at Kudra.

Work in Progress:

At IR Km 581/5 near Kumahu station, new SSP shifted/ Commissioned on IR side on account of DFC .

OHE mast foundation work completed at IR Km 581/11-12 (Ch. 31.177).

At IR Km no. 581/4-5 near Kumahu station, foundation work for S&T Relay room is under progress.

220/132 Kv Dehri On Son GSS of BSPTCL. Feed to DFC TSS NKWD will be supplied from here. DFCCIL track


NOTE: At new Durgawati station the IR junction point is as per the plan but due to some

land issue and other reasons, the IR junction point has been shifted about 2 Kms before the Sasaram station (MGS end) instead of at New Karwandia station. The meeting of Dir/PP with the IR took place on this and other issues on 4.9.2014 at MGS to exactly decide the IR Junction point.

At Pahleja , the IR station building coming in DFC alignment along with one SSP and microwave tower. All these are being shifted.

At new Karwandia, the station building is near completion. Ballast spread for yard. This DFC station is in front of the IR Karwandia station. Between IR junction point and the adjacent LC-38, one SSP is there but is not infringing the DFC alignment.

At LC-42 at Sasaram station at HWH end, the Aara line is diverging on DFC side. Same issue to be resolved at higher level. At present diamond crossing probably will be made.

Near Ganjkhwaja (IR station near MGS at SSM end), the RFO is proposed and from this location the DFC track will run from south to North of IR track.

EHT power line crossings are being done by the DFCCIL through separate open tender. Bid documents were under finalization.

At Present the OHE feed to the DFC line will be given from the IR TSS/Kudra.

The DFC SONE Bridge:

The Existing old Iron bridge was commissioned in 1900. At present the bridge is in operation with the CD.

The second IR bridge is commissioned adjacent to the existing bridge by the M/s AFFCON. The train operation on new bridge with three line is likely to be started in near future. This bridge is erected on pile foundation.

The DFC bridge will be third Railway bridge. The work is being executed by joint ventures of M/s ATEPL (Arvind Techno Enterprise Pvt. Ltd.) & M/s MGCPL (Mittal Group Construction Pvt. Ltd.). The work is started in Feb’2014.

The bridge is being erected on well foundation. The DFC/MGS unit chainage starts from center of the first abutment

(HWH end) of this bridge. The DFC bridge is having 92 piers and 2 abutment with a total length of 3.06 Kms.

Sh. Sumit Kumar, Exe(Civil) is looking after the bridge work from DFC side.

The salient features and milestones of the bridge is given in next slides.APM/EL/AII & ABR on 4-5.9.2014
