Geological StudiesMechi-Mahakali – Loose fluvial sediments of the Indo-Gangetic Plain (Terai) and sedimentary rocks of the Siwalik Group (mudstone, sandstone, pebbly sandstone and conglomerate) Through the Himalayan Frontal Thrust (HFT). Strike of bedding plane extends nearly northeast to southwest direction and dips toward north direction. Soil erosion in the Indo-Gangetic Plain may affect the alignment during the flood disaster because of presence of loose sediments. Tunnel alignment through the rocks of the Lower Middle and Upper Siwaliks 10 to 30% very poor rock 10- 40% poor rock 20-30% fair rock.
Geological Studies (contd..)Tamsariya – Abu-khairani Rocks of the Siwalik and Lesser Himalaya as well as the sediments of the Indo-Gangetic Plain. Rocks of Lower Siwalik and comprise of thick mudstone and sandstone. At Bharatpur, the Dun valley sediment found Dip direction of the foliation plane and direction of the tunnel alignment are nearly perpendicular.Kathmandu-Pokhara Low- to high-grade metamorphic and sedimentary rocks of the Lesser Himalaya, Central and Western Nepal Himalaya.

Environmental & Social Impact
Environmental & Social Impact The elevation ranges from 80m to 120m in Mechi- Mahakali alignment and 260m to 1300m Pokhara -Kathmandu alignment respectively Mechi Mahakali alignment - tea garden, mango garden. Shuklaphanta Wildlife Reserve, Chitawan National Park, Parsa Wildlife Reserve, Koshi Tappu Wildlife Reserve These ecologically sensitive areas are rich in floral and faunal diversity. Tamsaria-Abukhaireni Alignment consists of sal forest, nearby Abukhaireni a patch of Scima-Castenopsis forest also exists.
Environmental & Social Impact (Contd..) Kathmandu- Pokhara – hill sal forest, subtropical deciduous hill forest and subtropical conifer forest. Forest is the prime source of fuel-wood, fodder, timber, medicinal herbs and even agriculture manure Passes through many community forests Protected species - Sal, Khayar, Chanp, and Okhar
Environmental & Social Impact (Contd..) Requirement of Land Forest Area – 2661 ha Agriculture – 4527 ha River – 222 ha Barren – 56 ha Settlement – 239 ha Tunnel – 312 ha Others – 9 ha Total – 8027 ha
Environmental & Social Impact (Contd..)Details of settlements falling in (1km wide influence area) Mechi-Mahakali Population-3,40,113 Households-58,327. Tamsaria-Abukhaireni Population-24,380 Households-4160 Pokhara- Kathmandu Population-58,036 Households-10,104 Connections to Indian border town Population-8,508 Households-1,418
Environmental & Social Impact (Contd..) Main occupation of Mechi-Mahakali area is agriculture. Also, people are involved in cash crop production, commercial livestock, poultry farming, horticulture, business, cottage industry etc. Similar occupation profile in Pokhara- Kathmandu alignment also. Majority of the people in the Mechi-Mahakali corridor are local inhabitants. Only a few households constitute the immigrants from the distant area or neighbouring districts. In Pokhara- Kathmandu area only a few households constitute the immigrants from the distant area or neighbouring area.
Environmental & Social Impact (Contd..) The proposed railway alignment will change the land use pattern of the project area. Both adverse and beneficial impacts are expected Mechi-Mahakali alignment - 2247 ha. of forest Tamsaria-Abukhaireni - 187 ha. of forest Pokhara -Kathmandu -151 ha of forest In Connections to Indian border towns-75.15 ha. of forest
Environmental & Social Impact (Contd..) Positive impacts Creation of employment opportunity. May check out migration of the area. Better connectivity will improve industry competitiveness reduce cost of production and reduce pollution Approximate cost of land and mitigation - NPR 2682Crore

TRANSPORT DEMAND FORECAST
Project Influence Area* 24 Districts in Mechi – Mahakali section 6 Districts in Kathmandu – Pokhara section Project influence area covers 40% districts and 66% population of Nepal. * Project Influence area is taken 50km on either side of the proposed alignment.
Study Approach• Review of Secondary data and previous reports.• Field surveys at strategic points.• Meetings with different Government, Non-Government and Private Agencies.• Opinion surveys among different segments of the potential rail users, both in respect of freight and passenger.• Assessing and quantifying divertability of freight and passenger traffic from other modes of transport to rail.
Primary SurveysPrimary survey was conducted to: Understand the existing traffic on the corridor Passengers likelihood to use the new mode viz. Rail To assess the journey time/costs To use the proper statistical hypothesis to estimate the likely demand for the new mode.Primary surveys were conducted at 15 locations.
Primary SurveysMAJOR POTENTIAL PASSENGERS ORIGINATING POINTS PER DAY
Industrial Survey Most of industries contacted welcomed the new mode of transport. Qualified their inclination for quantum shift with: Assured transit time; Freight handling facilities; and Integration with other modes of transport for smooth transfer of freight.
Passenger Opinion Survey Around 90% of the bus travellers & 75% of the car travellers were in the favour of new rail connectivity in view of: • Better & safe mode • Avoid traffic congestion and • Result in development of country. Cost of travel, comfort level and time savings are the reasons behind selecting a particular mode of transport.
Base Year Traffic : 2009-10 Freight (Million tonne) 38.850 Passenger („000) Bus 37574 Car/Taxi 9410 Air 1428 Total 48412
Origin - Destination Flows not Considered Following O-D flows not considered for shift to rail: Origin – Destination not falling in the Project Influence Zone. Commodities not amenable to rail transport such as perishables, milk & milk products, confectionery, glassware etc. Commodities moving less than 100 kms distance left for road sector . Origin – Destination not expected to run on Railways due to higher time & cost.

Rail ShareThe traffic diversion from road to rail has been based on Cost of movement to Users The following factors mainly influence the choice of mode in transport » Freight / fare Charges » Transit Time » Reliability » Inventory / value of time Opinion surveys conducted from the users (passengers and industries).
Passenger Opinion Survey The rail mode was found to be economical for the passengers by bus as they had both time and cost savings. Though not much of savings in journey time was observed to personalised vehicle passengers, but there was substantial cost savings by switching over to new mode.

Preparation of DPR Project execution in phases as: The requirement of funds is huge There is no trained manpower in Nepal for construction of Railway line Prioritisation of sections Work of DPR to be outsourced Dedicated team of Engineers for overseeing DPR
Components of DPR Marking the centre line of alignment on the ground. Detailed Geological mapping of the tunnel portion Detailed hydrological investigation of the major bridges including model analysis Geotechnical investigation at the location of major bridges, tunnels, deep cuttings and high embankments. Detailed design criteria for various systems and structures.
Components of DPR Preliminary design of tunnels, bridges, track, signalling and electrification system etc. Environmental Impact Assessment Detailed operation plan. Detailed Yard Plans Recommendations regarding specification of rolling stock & other components. Detailed cost of the project. Recommendation regarding constitutional and legal provision to be made. Recommendation regarding packaging of contracts. Financing arrangements of the project.

Economic Appraisal Carried out “With” and “Without” the Project Approach With the Project - Covers Year to Year Entire Capital and Operation Costs by Proposed Rail services Without the Project- Relates to Costs involved in Handling Estimated traffic by Alternative mode (Road) Gap Between the Two Costs Brings out Net Margin to the Economy Due to the Project.
Economic Appraisal (Contd.) With The Project : (On Rail Services) Direct Costs: Construction, Rolling Stock, Operation & Maintenance, Road VOC- Feeder services, Transshipment & Inventory Without the Project : (On Road Movement) Direct Costs: Road Augmentation, Highway, Road VOC, Transshipment & Inventory.
