Sahibganj loop
The Sahibganj loop is a railway line connecting Khana Junction and Kiul Junction. Originally a part of the Howrah-Delhi main line, it was opened to traffic in 1866. With the construction of a shorter railway line for a part of the route, the stretch was assigned a separate identity.
History
Railway transportation was introduced in India within 30 years of its maiden run in England.The East Indian Railway Company which was formed on 1 June 1845, completed its survey for a railway line from Kolkata, then called Calcutta, to Delhi via Mirzapur in 1846. The company initially became defunct on refusal of government guarantee, which was given in 1849. Thereafter, an agreement was signed between East Indian Railway Company and the East India Company, for the construction and operation of an "experimental" line between Kolkata and Rajmahal, which would later be extended to Delhi via Mirzapur. Construction began in 1851.
On 15 August 1854, the first passenger train in the eastern section was operated up to Hooghly, away. On 1 February 1855 the first train ran from Hooghly to Raniganj, from Howrah. The priority accorded to the Raniganj section was because of the assurance of coal transportation.
The Khana Junction-Rajmahal section was complete in October 1859, crossing Ajay River on the way. The first train ran from Howrah to Rajmahal via Khana on 4 July 1860. The Loop from Khana Junction to Kiul via Jamalpur, including the Monghyr branch, was ready in February 1862.
From Rajmahal, construction progressed rapidly, moving westward along the banks of the Ganges, reaching Bhagalpur in 1861, Munger in February 1862, and opposite Varanasi in December 1862 and then on to Naini on the bank of the Yamuna. The work included EIR's first tunnel at Jamalpur and first major bridge across the Son River at Arrah.
During 1863-64, work progressed rapidly on the Allahabad-Kanpur-Tundla and Aligarh-Ghaziabad sections. The Yamuna bridge near Delhi was completed in 1864 and EIR established the Delhi terminus. The Yamuna bridge at Allahabad opened on 15 August 1865 and in 1866 Kolkata and Delhi were directly linked. The 1 Dn/ 2 Up Mail started running.
With the completion of the long line connecting Raniganj with Kiul in 1871, a "shorter main line" was in position. Initially, it was called the chord line. However, as it attracted more traffic it was designated the main line and the original line became the Sahibganj loop.
After approx 150 years of operation, Sahibganj loop is converted in double line on 14-05-2019 except Ratanpur–Jamalpur section as construction of tunnel near Jamalpur is in progress. Train operation with Electric Loco in Kiul-Bhagalpur section is Started on 03-06-2019.
In the Rail Budget 2008, Bhagalpur was announced to be converted to as Railway Division and yet to be completed by ER. The new rail lines from Sultanganj to Deoghar announced and the construction yet to start. Bhagalpur to Dumka section is operational. Bhagalpur to Deoghar via Banka section is operational.
Bhagalpur Godda via Hanshdiya is under construction.
Branch lines
In 1863, the Indian Branch Railway Company, a private company opened the Nalhati–Azimganj branch line. The track was initially a 4' gauge line. The track was subsequently converted to 5' 6" broad gauge. The Indian Branch Railway Company was purchased by the Government of India in 1872 and the line was renamed Nalhati State Railway. It became a part of the East Indian Railway Company in 1892.In 1913, the Hooghly–Katwa Railway constructed a line from Bandel to Katwa, and the Barharwa–Azimganj–Katwa railway constructed the Barharwa–Azimganj–Katwa loop line.
The Andal-Sainthia Branch Line was built in 1913.
The long Ahmedpur Katwa Light Railway connecting Ahmadpur Junction railway station and Katwa Junction railway station, built on, was opened to traffic on 29 September 1917.
Bhagalpur to Dumka section is operational. Bhagalpur to Deoghar section via Banka is operational.
Mirjachauki–Godda and Godda–Hanshdiya is under construction. Bhagalpur will directly connect with Godda via Hanshdiya.
Developments
Only Ratanpur to Jamalpur of the Sahibganj Loop is still operating on single track. Work of construction of Second Tunnel Near Janalpur is in progress. Second tunnel work near Jamalpur is likely to be completed by 2021. Twenty-one pairs of trains ply between Bhagalpur and Sahibganj.New Rail Line From Pakur-Godda and Bashukinath Dham - Chatra is proposed.
Work for doubling the stretch started in 2010.
Work on the new long Rampurhat-Dumka-Mander Hill broad gauge line completed and Kavi Guru Express BhagalpurJn to howrah is running on this route.
Jamalpur Workshop
Jamalpur Workshop, the first full-fledged railway workshop facility in India, was opened on 8 February 1862, at a time when the Howrah-Delhi main line, passing through Jamalpur was under construction. It was felt that communities of gunsmiths and other craftsmen in the area handling mechanical engineering jobs could pick up the skills required in a railway workshop. It undertook repairs of wagons, coaches, cranes and tower cars, and locomotives, as well as manufacture of some tower cars, break-down cranes and various kinds of heavy-duty lifting jacks. They also produced their own locomotives, starting with the CA 764 Lady Curzon in 1899. It has also produced ticket printers and other ticket machines. With fairly extensive workshop facilities, it was a fairly self-contained.Electrification
Electrification of the Khana - Rampurhat - Sainthia - Pakur section was announced in the rail budget for 2010-11.The electrification of Ahmedpur - Khana - Sainthia - Rampurhat - Pakur - Bonidanga section was completed in 2016. The first electric train service started from 29 September, 2016 through running of Howrah - Rampurhat Express by Electric Locomotive.
The electrification of Bonidanga Link Cabin - Barharwa - Sahibganj - Kiul section Including the Tinpahar - Rajmahal section has been started from September 2017 and was expected to be completed by the end of March 2020 but got delayed due to a pandemic and was completed on 30th June 2020.
After approximately 150 years of operation of Kiul - Bhagalpur Section of Sahibganj Loop Rail Line, Vikramshila Express became the first train to be hauled by an electric locomotive on 2nd of June, 2019.
After the electrification of Bhagalpur to Kiul first train With Electric Locomotive on this loop was started on Vikramshila Express between Anand Vihar Terminus to Bhagalpur hauled by WAP 5 of Ghaziabad Shed. The next day it departed and ran with the same Electric Loco from Bhagalpur Junction till Anand Vihar Terminus. By then almost 8 pairs of express trains originated from Bhagalpur begun its operations by electric locomotives.
The electrification of the further loop line between Bhagalpur to Bonidanga Link Cabin was delayed due to doubling of Sahibganj - Bhagalpur section which was completed in the month of April 2019.
After the complete electrification work was then resumed between Bhagalpur to Bonidanga in 4 stages which began from both sides as the Bonidanga - Barharwa section was electrified within 1 month in First Phase.
The work was then resumed between Barharwa - Tinpahar which was completed within 2 months in the Second Phase.
Within that time Doubling work between Bhagalpur to Kahalgaon section was completed but, it was again delayed due to Route - Relay Interlocking work so, electrification work from Bhagalpur section was paused due to RRI work.
After the electrification of Barharwa - Tinpahar section, Tinpahar - Sahibganj section was electrified in the Third Phase and its CRS Inspection was done between Sahibganj to Barharwa.
The Fourth Phase of electrification was done between Sahibganj to Bhagalpur into two parts.
- Sahibganj - Shivnarayanpur - Completed on February 2020
- Shivnarayanpur - Bhagalpur - Completed on March 2020, CRS Inspection was done on 30 June 2020.
As the newly electrified section of Bhagalpur – Shivnarayanpur portion under Eastern Railways’ Malda division was completely electrified, train number 05956/05955 Delhi-Dibrugarh-Delhi Special Brahmaputra Mail was the first passenger train from Delhi to reach up to New Jalpaiguri with an Electric Locomotive. According to the NFR zone, the national transporter will save an amount of around Rs 20.4 crore per annum in its fuel cost, for running this train on electric traction between Mughalsarai Junction and New Jalpaiguri Jn railway stations.
Finally, the whole Sahibganj loop route has been electrified and the last CRS inspection was done on 30 June 2020 between Bhagalpur and Shivnarayanpur.
More electric trains to run soon in this route after notification.
