prospective Electrical Railway Technology in Nepal"
Nepal is a developing landlocked country. There are lots of efforts needed to develop the transportation sector of Nepal. The cheapest means of transportation i.e. waterways is out of the blue for Nepal. The main transportation of Nepal is roadways, aviation mode, primitive railway and traditional porter means. Nepal has to focus on developing and enhancing the possible means of transportation. In the case of developing and enhancing transportation system of Nepal, it is necessary to focus on mass transportation system. So, that almost all general public can be a passenger and can be benefited by daily consumers' goods and services from the cheap mass transportation system.
Nepal is spending bulky chunk of foreign earnings in importing the fossil fuels. The vehicles plying are consuming fossil fuels. Also huge portion of fossil fuels is used to generate electricity at home, office and industrial sector. Nepal has tremendous potential of hydropower energy. i.e. about 43,000MW. The transportation sector has to focus on using this hydropower energy rather than spending and eroding national economy by importing fossil fuels. One of the best options for Nepal is using Electrical Railway System which is both mass transportation system and uses electrical energy for operation.
In 2010, the feasibility study for developing Electrical Railway in Mechi - Mahakali Section and Pokhara - Kathmandu Section is being done in association of RITES of India and SILT Consultancy of Nepal.
Our study for studying energy and technological assessment of prospective Electrical Railway System in Nepal, is confined to the different routes developed through the feasibility study report prepared by RITES and SILT.
This study focuses on the electrical railway system. It studies the basic technical aspects and capacity of the locomotives designed for passengers and the freights. The study focuses on WAP 5 and WAP 7 for the locomotives and WAG 9 for the freights transportation. It studies the potential passengers' scenario and freight scenario on the influence zone of prospective electrical railway systems. On the basis of passengers and freights of 2009/10 projected on the feasibility report of RITES and SILT, transportation modelling for different route is done. Also the probable energy consumption and energy cost for the model developed on the process of study is carried out.
The four routes for passengers' service are being selected for transportation modelling. The findings and results for 4 different routes are as follows:
1) Kathmandu - East Route
2) Kathmandu - West Route
3) Kathmandu- Pokhara Route
4) West - East Route
For the round trip in all above route it needs at least 14 number of Wap-7 loco with passenger hauling capacity of about 2200 or 18 number of WAP -5 locos with passenger hauling capacity of 1800 in each trip.
The main freight originating point is Birgunj and destination point is Kathmandu. Also, Birgunj Kathmandu sector has 16 % of the total freight of Nepal. About 40% of the total imports and exports is done from the Birgunj. So, the Birgunj - Kathmandu route for freight calculation is chosen for the study. For running smooth freight train operation from Birgunj to Kathmandu, it requires 4 + 1 or 2 extra WAG 9 locomotives with more than 230 wagons to carry freights. It needs 32 WAG-9 locomotives to operate freight operation through out the selected routes. The total investment for 18 WAP-5 loco is 374.4 crores which is less than total investment in WAP-7 locos i.e. 439.04 crores. But the total energy cost of 18 WAP-5 locos is 9.8734 crores more than the total energy cost of 14 WAP-7 locomotives. So it is recommended to use WAP 7. Finally, there are many direct and indirect benefits of the Electrical Railway System. The cost for construction is very high and it is not likely to get...
