Railway electrification in Iran describes the past and present electrification systems used to supply traction current to rail transport in Iran with a chronological record of development, a list of lines using each system, and a history and a technical description of each system.

The project is sometimes abbreviated to RAIELEC,[1] in which RAI is the abbreviation of Islamic Republic of Iran Railways ( Persian: برقی کردن راه آهن در ایران , abbr: بكرا ).



[edit] Definition

An electric container freight train on the West Coast Main Line, United Kingdom.

Railway electrification means to equip the railway (Rail transport) infrastructure with wires Overhead lines, or Third rail with electric current to feed the locomotive or electric multiple unit.

[edit] History

Railway electrification in Iran has started in 1975 (the initial negotiation in 1969)with a contract with Russia to electrify Tabriz [1] Jolfa route with 146 km at north west of country in East Azarbaijan Province near the border of former SSSR Soviet Union with Bogie exchange facility. Tabriz Jolfa was originally established in 1916 (before the main network in 1938) with the wide gauge 1524 mm and was changed to standard gauge after connection of Tabriz to the national network.

[edit] Track geometry

Tabriz-Jolfa is a single line rail track with 146 km length (736 to 832) and 9 stations in between.max grade is 2.8% and min curve radius is 400.

[edit] Electrification specification

The electric line voltage is 25kV, 50Hz with three substations in Tabriz, Marand and Jolfa fed by 132kV from the national grid. Each substation at two ends has 3*15MW transformer and in marand 4 is used.

[edit] Recent projects

[edit] Pilot projects

Recently another contract was signed with Russian railway RZD in Feb. 2009 to connect the Tabriz electric line to "azarshahr" in south direction and will hopefully be continued to "bonab" and Maragheh and possibly to Urmia through Shahid kalantary bridge that has the rail track inside, like Oresund Bridge.

Also the existing electric line is going to be connected to Oroumieh and Maragheh and also Shabestar and Salmas relying on existing facilities and locomotives.

On the northern route it is planned to connect soofian to Shabestar and Salmas.

[edit] Main project

There was a tender [3] for electrification of tehran-mashhad double track line within 30 months with supplying 70 elec. locomotive with Cab signalling that will increase the speed to 200 km/h for Passenger car (rail) train and 250 km/h for tilting train Electric Multiple Train(EMU) reducing the existing journey time of 12 to 6 hours for pass. trains and from 7.5 of Siemens diesel multiple unit DMU (and 8 hours by turbo train)to less than 5 for EMU Electric multiple unit or possibly Push-pull train with two locomotives. The line is equipped with Optical fibercommunication and CTC center for Railway signal.

This project rather than electrification and locomotive, includes SCADA, 5 years maintenance, back up power generation & ... The contract is considered with maintenance and supplying Road-rail vehicle dual mode.

[edit] Effects on stations

Building of Central Tehran railway station by architect Vladislav Gorodetsky[[ <iframe src="http://wikimapia.org/s/#lat=35.6581331&lon=51.397562&z=15&l=16&m=s&v=2" width="250" height="250" frameborder="0"></iframe>]]

The Railway station layout specially in Railway stations in Iran and the mashhad root like Tehran and Mashhad Train station will be affected with electrification and the Railway platform in other stations could be longer in future.

[edit] New locomotive specification

The passenger locomotives (with (Bo-Bo) according to UIC classification of locomotive axle arrangements) continuous tractive effort is more than 240 kn and for freight (Co-Co) is more than 480 kn and the all weather adhesion is at least 33%. The passenger locomotives are equipped with head end power (HEP).

The desired locomotives prototype would be available 6 months sooner than end date of inauguration to pass the Homologation phase. The mockup and pilot experiment for EMU could be used to expedite the accepting process.

[edit] Tendering process

The initial study was done by RAI vice president for planning and international affairs in 2003 specially by calculating the benefit of electrification in locomotive saving in long passenger trains that was argued by the railway research center MATRAI. After convincing the top managers and management and planning organization,(MPO) it was approved by the government to make a Feasibility study for electrification and this was accepted by the parliament in 2007.

The study was carried out by a joint of Metra and Italferr according to United Nations Industrial Development Organization(UNIDO) andFIDIC recommendations and Tehran Mashhad was assigned as the first priority for being electrified. After this phase the Tendering Pre-qualification(PQ) was prepared by new Joint venture of Metra and Systra and Request for proposal (RFP) was released with conceptual design and by result obligations.

The realisation need to be observed according to international project management guides like PMBOK(Project Management Body of Knowledge), ISO 10006, Opm3 or PRINCE2. One of the main items emphasised was RAMS (reliability, availability, maintanability and safety) with quantitative measures and goals specially for MTBF (mean time between failures) and MDBF (mean distance between failures).

The review and modification of the design according to Value Engineering and Reliability engineering technique will be envisaged in the detailed design phase.

[edit] Future projects

[edit] Strategy

To promote the Electrification with more effectiveness, better performance and more productivity according the internal and external factors, a study have been done and a SWOT analysis table was created.

[edit] Planned projects

Railjet-Taurus in Saalfelden 2007

It is planned to expand electrification to the north west up to Tabriz (with 200 km/h speed for passenger trains and 250 for tilting EMU or such trains like Railjet) that is part of Silk Road and the transit route from Almaty to Istanbul and islamabad to Istanbul as one of main task and objectives of ECO Economic Cooperation Organization and one of the emphasized rout of ESCAP United Nations Economic and Social Commission for Asia and the Pacific.

The first phase of this project will be in tehran to Zanjan (city) to make it more economic and also to prepare the new under construction short cut from Tabriz to Mianeh that will decrease the distance from Tehran to Tabriz about 100 km and for this stepwise plan the dual mode or Electro-diesel locomotive could help to justify the project.

[edit] High speed projects

[edit] High speed history in Iran

THSR train started from 2006.

High speed railway in Iran was started by a visit to Japan shinkansen high speed trains by road and transportation minister in 1974.He asked Japan to prepare a proposal for construction of a new and dedicated HSR from Tehran to Mashhad. According to this a delegation was sent from JARTS to do this and finally they proposed three options i 1976 as follows:

[edit] 1- Double tracking and electrification of existing line with 160 km/h

Track at that time had single line without electric signaling system, with lot of curve with 300 meters radius.(with estimated cost of about 1 $B)

[edit] 2- A dedicated high speed line with 210 km/h

The Max speed in Japan at that time was 210 km/h and there was no other railway with high speed unless Japan.(with estimated cost of about 4 $B)

[edit] 3- A dedicated high speed line with 260 km/h

This option was according to the long realisation time of such a huge project with an estimation of about 10 years.(with estimated cost of about 7 $B)

[edit] Other high speed projects

There are other lines that have been nominated, studied and approved for high speed railway like Tehran-Isfahan, Tehran-Qom and ... and the first one have been started and is under construction.

[edit] Electrification step to high speed

High-speed lines in Europe.      320–350 km/h      300 km/h      250–280 km/h      200–230 km/h

This project will enable the economically introduction of High-speed rail HSR gradually perhaps from Garmsar to Semnan, and the final goal is to have less than 3 hours for wide body high speed trains in a dedicated high speed line with road rail parallel layout.

There are two high-speed rail line projects in Iran, between Tehran and Isfahan, as well as Tehran to Mashhad. The Tehran-Isfahan HSR speed has been increased to 350 km/h and the section between Tehran and Qom is going to have a new dedicated alignment for 350 km/h connecting tehran to Imam Khomeini International Airport possibly connected by monorail, and to new multi mode terminal in Qom with a road rail parallel layout with freeway connecting to Isfahan HSR.

[edit] Maglev option for high speed

There are some possibilities to use the Maglev (transport) with Linear motor for high speed needs starting according to reliability and life cycle cost (LCC) with a Pilot experiment in short distance like tehran-karaj.

[edit] Road Rail Parallel Layout

Road Rail Parallel Layout is an approach that uses the land around the road to pass the railway lines, like the line from Paris to Lyon with 15% along highway and Koln to Frankfurt with 70%.[4]

Construction of the route through the Kösching forest, north of Ingolstadt, had a large environmental impact but with Road Rail Parallel Layout this would be less than using multiple routes.

[edit] Tunneling compatibility

By electrification it would be possible to choose the routes with longer tunnels like the Gotthard Base Tunnel tunnel in switzerland.[5]

[edit] Existing network connection

By electrification it would be possible to connect more cities to high speed network like arak, yazd, ahwaz, shiraz, kerman and in north west corridor to tabriz, ardabil and ...

400 3 1000 1800 1000 300 1700

The main factors that are different in above options could be referred to as the equipment for track and electrification that will be increased by speed and also the rolling stock that for higher speed will have a small higher price about 10% but the productivity that increases considerably because of lower time of trip that enables more density of seats with seat pitch about 50%.

On freight corridor, the electrification of Bafgh bandarabbas in Persian Gulf is planed as BOT Build-Operate-Transfer base with future continuation to Tehran and Intermodal freight transport at both ends plus the Classification yard.

The rate of return on investment would be very acceptable specially for international investment [6] because of enough demand between bandarabbas to Tehran with only 10% share of railway Freight train because of capacity limitation.

Bandarabbas is close to Gheshm Island that has 100 km length and could be connected by bridge or tunnel (like Channel Tunnel) or Marmaray in Turkey. One of the big advantages of this line is the big loading gauge and axle load that increases the productivity of the rail transport specially for intermodal freight transport by Well Car (double stack containers) from port shahid rajaee [7].

This line also can help to transit oil as a good start to the planed transit pipeline transport.

Iron ore is one of the main commodities on this line, especially from Golgohar mine near Sirjan, Choghart and Chadormaloo near Bafgh to Isfahan for two steel plants and steel mills named Zobahan (Esfahan Steel Company) and Mobarakeh.

The possibile use of roadrailers or rolling highway are some other options.

As the rail connection with Zahedan will be inaugurated in near future, it will make it possible to have a direct transit line from Central Asia to Pakistan and India possibly with variable gauge bogies and could be completed with a link to Chabahar port in the south east of the country.

The business plan to justify the electrification and supplying locomotives is going to be prepared.

[edit] Cost effective projects

For low density lines by doing cost-benefit analysis it is considered to use Dc elec. loco and the power from city substations for more Cost effectiveness of projects. For Lorestan province that there is more than 60 km tunnel, the DC diesel locomotive will be converted to electric.

For northern line (that has the grade of 3%) to Mazandaran and Golestan provinces one of the solutions could be third rail for using the existing diesel locomotives and dual-mode transit. The local production capability in electric energy sector makes the cost effectiveness better. for example the contact wire is produced a locally and also different insulators and there is god companies to wind transformers. With electrification, the need for shunting will be reduced and the Switcher locomotive as well. To improve the economic result of electrification it is foreseen to convert the diesel locomotives to electric one both in DC like GE E60 [8] and AC like AD43C. Value chain is a theory that could be used for this.

[edit] Electrification investment

Countries by 2008 GDP (nominal) per capita (IMF, October 2008 estimate)
GDP real growth rate 2007

Transport demand is increased more than GDP in freight and less than it in passenger sector, and it is essential to provide appropriate means for transport by investing in infrastructures.

According to the limitation in funds for electrification it is very important to increase investment for the extensions with good rate of return with different solutions rather than national budget as well as BOT as a Public-private partnership(PPP) type investment or a Concession (contract),Private finance initiative, Franchising, By back, Barter &...

Other sources of fund for Expansion of electric network is by believer people help for constructing the infrastructures for easy, safe and convenient transportation that is emphasized by Islam by Vaghf as a type of charity

Another solution is go for Privatization like Privatisation of British Rail or Japan. For more information it is possible to see the : Organization For Investment, Economic and Technical Assistance of Iran [9]

[edit] Electrification cost

The Electrification cost depends on the speed or the class of the track like Speed limits in the United States (rail). An initial and good estimate is done by world bank in 1984 with the name Railways and Energy [[10]]

According to the book of Prices and Costs in the railway sector by Professor Baumgartner from Switzerland [[11]] the rough estimation of traction substation cost is 0.2 million euro per megavolt amper and 0.2 million euro per km of line with 300 km/h and 0.15 for 100 km/h. It is possible to find some prices and cost data in following site.[[12]]

[edit] Electrification effect on safety

Detail of derailed EC 107 "Praha" in Prague (2007)

The electrification generally could have a reverse effect on safety but the consequences of it may increase safety a lot specially by increasing reliability, for example we can refer to the accident in neishabur as in Nishapur train disaster in List of rail accidents (2000–present) and derailment (Classification of railway accidents) in tight curves and high cant could be reduced by electrification .

[edit] World Electrification

Railway electrification in Europe by country. Data source: UIC

In 2006 25% (240,000 km) of the world rail network was electrified and 50% of all rail transport was carried by electric traction (both by locomotives and multiple units) and about 36% of electric system is 25 KV AC.

[edit] Electrification Advantages

Electrification of railway like every other phenomenon has some positive and negative results. some of advantages of electrification are as follows: less weight and space for same power (thus less locomotive need in big passenger trains), less maintenance(more availability and less cost in locomotive purchasing), less power losing in elevation and warm weather

[edit] Electrification Disadvantages

Snabel car with an electrical transformer near Koblenz

There are many argument about the electrification and may people believe it is not feasible to electrify the railway in many cases. Some of these experts say with the need to expand network it is better to invest for expansion programs.But it is important to say that there is not a general rule for accepting or rejecting this phase and the best approach is to evaluate all of the consequences of electrification either positive or negative. One of the restrictions of electrification is the clearance for large size commodities like double stack containers and big transformers and ...

[edit] Fuel saving

US gasoline prices, 1919-2007 (real and inflation adjusted)

One of the advantages of electrification is fuel saving, because of the cheaper method of electricity generation in power plants that uses either coal or some other sort of energy like gas, heavy fuel with max. efficiency of 55% and Cogeneration (CHP) with about 90% eff. and ... also the Bioenergy,Waste management, hydro electric and nuclear energy.[[13]][[14]][[15]]

According to the world Energy statistics [16] the reserve of liquid fuel is much less than gas and coal ( 15, 60 & 150 years respectively)so it is vital to increase the railway share in transport and to go for electrification because of source of useful energy in different modes. We can consider electrification as one of the important means to consumption pattern reform [17] [18].

[edit] External Cost

The External Cost of railway is lower than other modes of transport but the electrification brings down it even more, if it is Sustainable.

This is specially due to Railway safety to Road traffic safety with regards to Value of life. Also energy from well to wheel, and the necessity to reduce pollutions and greenhouse gas in earth according to Kyoto Protocol.

To have better interaction with society, using the help of Think tank organizatins (NGO) is vital.

[edit] Modes interaction

Electrification means higher speed for pass. and thus needs the railway to have better connection to other modes of transport like metro, light rail transit(LRT), monorail, Bus rapid transit(BRT), airport and Airplane for Flight &....

[edit] Research & Development

Another result of electrification is the affect on locomotive and wagon productivity and it is going to be more effective by more railway research in this field. The trend of technology in railway electrification is very important to adopt the efforts for better results, for example the trend from GTO (Gate turn-off thyristor) to IGBT (Insulated-gate bipolar transistor) for more powerful locomotive with higher reliability is one of the elements of Technology roadmap (TRM) and the loop to have a mature system as in Maturity Road Mapping with the Technology transfer provision. It is necessary to predict future by the skills of Futurology and to prepare the suitable conditions for Technomart [19] .

[edit] Railway Electrification Statistics

It is an important stage to use the traffic data according to railway statistics like in Rail usage statistics by country. and UIC in 2007 and (List of countries by GDP (PPP) per capita).
