REPUBLICA
KATHMANDU, March 8: The government has completed final preparation to establish the Department of Railway (DoR) with the vision of developing 4000 km railway line across the country within 20 years.
The Ministry of Physical Planning and Works (MoPPW), which will oversee the DoR upon its formation, recently finalized the Organization and Management (O&M) survey and sent it to the Ministry of General Administration (MoGA) to forward it to the cabinet for approval.
The government decided to form the DoR to speed up the process of constructing different railway project across the country.
Ram Kumar Lamsal, who was involved in preparing O&M survey, said the DoR would have a total of 35 staffers, including three joint-secretaries, seven under-secretaries, 12 section officers and 13 non-gazetted officers. Annual budget for the department has been estimated at Rs 7.5 million.
"The Department of Railway will be formally established once the cabinet approves the O&M survey," said Lamsal, who is heading the Railway Project that is overseeing railway related works under stop-gap basis.
The Ministry of Finance has already given its consent to form the department. Upon formation, the department will oversee construction and management of railway, metro rail, ropeways and cable car lines in the country.
Lamsal, who is also a joint-secretary at MoPPW, said the department has set a vision of increasing railway line to 4,000 km, including the East-West Railway, Kathmandu-Pokhara Railway, Kathmandu-Tibet Railway and railway lines that connect major bordering towns of India and Nepal, within 20 years.
"We have also set a target of building 150 km metro line in the Kathmandu Valley, extend existing ropeway to 1,500 km and establish at least 60 cable car lines within the period," Lamsal told Republica on Monday.
The to-be-formed department will also complete the Detailed Project Report (DPR) of Janakpur-Bardibas railway line and bring the Nepal Railways Company under the purview of the MoPPW. Existing acts specify the Ministry of Labor and Transport Management as the authority to oversee works related to railway.
The document provides information about Pradeep Vyas's practical training at the Northern-Western Railway Workshop. It discusses the various shops within the workshop including the power shop, air conditioning shop, train lighting shop, and production and control department. It describes the key equipment and processes used in each shop's operations for maintaining railway equipment. The workshop provides hands-on training for engineering graduates and technicians.
This document provides an overview of the Transportation Engineering II course syllabus and discusses various topics that will be covered, including railway geometric design, station and yard design, airport engineering, and harbor and dock engineering. It also summarizes key concepts related to permanent way design, including subgrade, formation, embankment, track drainage, rails, rail fastenings, sleepers, and ballast. Modern trends in rail such as MAGLEV, tube, and metro rail systems are also introduced.
The Electric Loco Shed in Ghaziabad was established in 1976 by the Railway Electrification Organisation to maintain electric locomotives. It currently holds 185 locomotives used to haul passenger and freight trains. The shed maintains WAP1, WAP4, WAP5, WAP7, WAG5 and WAM4 series locomotives, which use technologies like DC traction, AC traction, and IGBT-based propulsion. The locomotives are maintained and repaired at the shed to keep them in service.
This document discusses various aspects of railway engineering including ballast, sleepers, rails, points and crossings, tractive resistance, track stresses, hauling capacity, buckling due to temperature stresses, and stresses in rails, sleepers, ballast, and formation. It covers topics such as the components that make up the track, factors that influence tractive resistance and track stresses, and how stresses are distributed throughout the track components and subsurface.
The branch of Civil Engineering which deals with the design, construction and maintenance of the railway tracks for safe and efficient movements of trains is called Railway Engineering

(2) Flat Footed Rails (F.F. Rail)
(3) Bull Headed Rails (B.H. Rail)
Signaling systems in railways convey information to train drivers regarding train movements. The two main types are time interval and space interval methods. The space interval method divides tracks into blocks and only allows one train per block, ensuring space between trains. It uses visual signals like semaphore arms and color light signals, as well as audible signals. Track circuits, points, and slots are also key signaling elements that detect train presence and enable route setting and dual control of infrastructure. The goal of signaling is to safely dispatch and receive trains at stations by controlling train movements between stations through block systems.

13. Vad behövs för att utveckla den
Railway Group
europeiska infrastrukturen?
• En gemensam vision och plan för både ett höghastighetsnät
och för godskorridorer – inte bara en sammanläggning av
nationella planer
• Åtgärder för att vidmakthålla och förbättra infrastrukturen i
de nya EU-länderna EU12
• En gemensam standard för godstrafik med längre godståg,
högre axellast och större lastprofil
• En snabbare utveckling av ERTMS level 3 med flytande block
som verkligen ger högre kapacitet
• Medel för att stimulera utbyggnad av infrastrukturen som
kombineras med krav

15. Vad krävs för att nå så hög
Railway Group
marknadsandel?
För persontransporter:
• Utbyggt höghastighetsnät från 6000 till 36 000 km, 30% av huvudnätet
• Uppgraderat konventionellt nät
• Effektivare tåg för att minska kostnaden
• Avreglering för att sänka priserna
För godstransporter:
• Effektiva godskorridorer utan gränser
• Bättre service genom avreglering
• Effektivare tåg (längre, tyngre, bredare, högre) för att minska kostnaden
• Utvecklad kombitrafik med automatisk terminalhantering

18. Hur öka kapaciteten?
Railway Group
• Persontrafik: Dubbeldäckare och wide body tåg, längre tåg:
+ 25-50%
• Godståg: Längre tåg, tyngre tåg, högre axellast och
metervikt, större lastprofil: +25-50%
• Nytt signalsystem ERTMS level 3: +40%
• Bygga höghastighetsbanor:
2-3 gånger högre kapacitet för gods- och regionaltåg på det
konventionella nätet nör snabbtågen lyfts bort
6-10 högre kapacitet för snabbtågen på höghastighetsbanan
Kortare restider och bättre punktlighet
• En ökning av kapaciteten 4-5 gånger är fullt möjlig men
kräver investeringar I nya banor
KTH Railway Group • Center for research and education in Railway technology - Railway development in Sweden 18
19. Hur finansiera inveteringarna?
Railway Group
• Möjligheten finns att omfördela inveteringar fråm väg till
järnväg eftersom vägtrafiken inte kommer att öka så
mycket
• Tabellen nedan visar ett räknexempel med utgångspunkt
från dagens investeringsnivå

21. Slutsatser
Railway Group
• EU:s vitbok innebär en radikal förändring av Europas
transportsystem – särskilt för långväga transporter
• Marknadsandelarna med mode shift ungefär samma som i
best practice för järnväg i dag
• Efterfrågan på järnväg blir 4-5 gånger större än i dag
• Ett utbyggt höghastighetsnät som frigör kapacitet och
gränslösa godskorridorer är förutsättning
• Ger ökad rörlighet och effektivare godstransporter
• Stora investeringar men viss omfördelning från väg till
järnväg kan vara en lösning
• Det behövs mer forskning och utveckling av
järnvägssystemet
