Detail Survey and Design of Electrified Railway Line Simara – Tamsaria Sector of Mechi – Mahakali Electrified Railway Line (127.08 Km)

Project Description

In pursuance of the Government’s objective of development of railway as an alternative mode of transport in Nepal, Ministry of Physical Planning and Works, Department of Railways, has decided to carry out detail survey and design of the Simara- Tamsaria section of proposed Mechi- Mahakali railway line with design speed 160 km/hr. The proposed new railway line normally runs parallel to the East – West Highway. Simara and Tamsaria are small towns in Tribhuwan Rajmarg and Mahendra Rajmarg respectively are situated at 585 km and 471 km of the of the proposed Mechi –Mahakali railway alignment. The railway alignments proposed for detail design in this study is approximately 127.08 kilometres, 23.086 km approach road, 2 junctions at Simara and Tamsaria, Architectural Design of 11 intermediate stations, station buildings, station platforms, office & service buildings, residential quarters, sheds & workshops, 51 numbers of bridges (26.43 km) [Bridge Name and Span: Gindri River Bridge (length 147.43 m), Ban River Bridge (length 72.42 m), Laukaha River Bridge (length 122.42 m), Deusat River Bridge (length 122.42 m), Mukunde River Bridge (length 72.42 m), Khahare River Bridge (length 72.42 m), Krasot River Bridge (length 97.83 m), Shikaribas River Bridge (length 417.43 m), Bire River Bridge (length 97.43 m), Bakhariva River Bridge (length 347.43 m), Guhye River Bridge (length 122.82 m), Lategade River Bridge (length 72.43 m), Bhaluwahi River Bridge (length 382.46 m), Sukaura Dundwa River Bridge (length 47.52 m), Tilabe River Bridge (length 97.43 m), Jamuniya River Bridge (length 122.43 m), Manbojhi River Bridge (length 197.43 m), Mahadev River Bridge (length 97.43 m), Megha River Bridge (length 97.43 m), Bhedaha-1 River Bridge (length 97.43 m), and Bhedaha-2 River Bridge (length 97.43 m); Narayani River Bridge (length 1992.46 m), Lagauta River Bridge (length 47.63 m), Gajapur River Bridge (length 47.63 m), Chanauli River Bridge (length 72.42 m), Rodi River Bridge (length 72.43 m), Amritnagar River Bridge (length 47.43 m), Kerunga River Bridge (length 97.43 m), Postal Road River Bridge (length 6931.65 m), Chitai River Bridge (length 72.43 m), Magui River Bridge (length 172.43 m), Patero River Bridge (length 47.43 m), Parui River Bridge (length 172.55 m), Ghanghar River Bridge (length 297.90 m), Baghai River Bridge (length 8355.23 m), Dabuwa River Bridge (length 47.43 m), Aireni River Bridge (length 47.43 m), Amuwa – 1 River Bridge (length 47.82 m), Amuwa – 2 River Bridge (length 197.43 m), Amuwa – 3 River Bridge (length 97.82 m), Amuwa – 4 River Bridge (length 47.43 m), Amuwa – 5 River Bridge (length 447.43 m), Dheduwa River Bridge (length 147.43 m), Saraswatinagar River Bridge (length 147.43 m), Hanumannagar River Bridge (length 72.57 m), Thute River Bridge (length 372.43 m), Bagmara River Bridge (length 297.43 m), Jarayo – 1 River Bridge (length 97.43 m), Jarayo – 2 River Bridge (length 97.43 m), Nayabasti River Bridge (length 297.43 m), Indrabati River Bridge (length 2547.4 m)]; including 12 important bridges, 124 minor bridges, 20 RUB’s, 14 level crossing, Soil Investigation 173 Holes (2618 m) and 2.747 km tunnels (3 Nos.) with 8.1 m tunnel dia. are required in this section.
