The ICE 3 is not a Velaro, even though it looks similar. They don't have constant problems but regular ones in strong cold and heat, which is because of the set up DB has choosen. The Velaro in Spain and Russia is pretty reliable compared to that.

Ballasted track is easier to install, but is a pain to maintain: I read somewhere that the older Japanese HSR lines required nearly 5,000 people to maintain the tracks every night, since the ballast allowed the track geometry to deform. Aside from higher upfront costs (and being unable to change the route by even the slightest after construction), ballastless track is the way to go for high speed rail.

I think that the choice for Velaro rather than AGV is due to the fact that they
preferred to chose a proven design rather than a new set that nobody else
was using yet. I can understand they wanted to avoid all the debugging.
Yes, but the point is: the Velaro design to be used for Eurostar is new generation, not currently in use anywhere (not even in Germany). It's true that the older version of Velaro (known in Germany as ICE-3) has had a lot of trouble on LGV-Est, but Siemens must have convinced everybody that they now master those problems: Deutsche Bahn also bought the new design for its routes between Germany and France - predictably associated by howls of indignation from the French side of the border.

I think that this has more to do with Eurostar's ambition to start operating direct trains between London and Cologne/Frankfurt. That's probably easier to do with a train set developed by the Germans with the intent of using it on the Belgo-French network.

The new version of the train is called Velaro D. It was first delivered to Deutsche Bahn last year but not yet - as far as I know - used commercially. You can read the story here: http://www.siemens.com/press/pool/de..._velaro_en.pdf.

Not entirely true. The ICE 3 BR 403/BR406 has been built by Siemens and Bombardier together with a few smaller suppliers, while the Velaro which is in use in Spain and Russia is a Siemens-only product. So, while the exteriors are pretty similar, a lot has been changed on the inside including the new platform which allows the modifcations which are made for different customers. This would have not been possible with the ICE 3 / DB BR403/406.

Seems like this thread turned into a Siemens vs. Alstom argument instead of talking about Iraq's high speed rail ventures.

I will literally roll on the floor and laugh hysterically if Iraq manages to get its show going before America does.

Iraq can't beat the US because we have Acela, regardless how shitty it is compare to other HSR systems in the world, it's still a HSR.

You got something wrong here: The spanish high speed lines are all international gauge. I think that only russia runs high speed rail in a gauge different from the international.

Is this line Tehran - Mashad being constructed for HSR or just electrificated?

only electrification
The only real HSR line under construction in Iran is Tehran-Isfahan

Iran launches €2.4b high-speed rail project

http://www.tehrantimes.com/economy-a...-rail-project-

TEHRAN – The construction of a high-speed railway, extending about 400 kilometers from Tehran to Isfahan, started on Wednesday.

Iranian President Hassan Rouhani officially launched the project during a visit to the city of Qom, which is located between Tehran and Isfahan.

The railway is projected to be built over the course of four years at a cost of €2.4 billion. Trains running on the Tehran-Isfahan railway can reach speeds of about 350 kilometers per hour.

The project will save an estimated 550 billion rials (about $20 million) annually in fuel consumption.

Iran’s Bank of Industry and Mine will provide $1.8 billion of the total finance through China Export and Credit Insurance Corporation (SINOSURE). China Railway Engineering Corporation (CREC) will implement the project in cooperation with Iran’s Khatam al-Anbia Construction Headquarters.

An HSR300 proposal I just came up with for Tehran-West HSR Line

Total length 592 km
Sharing infrastructure from Tehran to Qom, so saves some costs there
Tehran-Arak: 1 h, down from 3h using Expway+FW, and down from 2h30 when Arak-Salafchegan-Qom FW opens
Tehran-Hamadan: 1h 25min, down from 3h 25min when using Freeway
Tehran-Kermanshah: 2h, down from 5h 45min using Expway+FW, compared to 1h 05min using plane

Xi-Rouhani talks: China to finance high-speed railway in Iran- Nikkei Asian Review

Xi-Rouhani talks: China to finance high-speed railway in Iran- Nikkei Asian Review

RIYADH -- Chinese President Xi Jinping and his Iranian counterpart, Hassan Rouhani, on Saturday agreed to a deal that calls on China to provide financial aid for the development of a high-speed railway in Iran.

The deal was among 17 agreements on economic and technological cooperation that the two leaders signed in Tehran.

Xi, who is currently touring the Middle East, became the first head of state to visit Iran since economic sanctions were lifted earlier this month as part of a nuclear nonproliferation agreement. He also met with Iranian Supreme Leader Ayatollah Ali Khamenei.

After the meeting, Rouhani said Tehran plans to significantly increase trade with China in the next 10 years to $600 billion from around $52 billion in 2014, according to the Iranian Foreign Ministry.

The planned railway is to connect Tehran and the northeastern city of Mashhad, Iran's second-largest city, along a route of about 900km. China is to undertake the project as part of Xi's "One Belt, One Road" initiative, meant to create a trade corridor between China and Europe. The agreements also confirm that the two countries will cooperate on the Chinese initiative.

During the meeting, Xi and Rouhani also discussed counterterrorism measures and increased tensions in the Middle East following the severing of diplomatic relations between Iran and Saudi Arabia. They agreed to strengthen their collective efforts to fight extremists.

Before Iran, Xi made stops in Saudi Arabia and Egypt. In a speech to the Arab League on Thursday, Xi unveiled a plan to spend $55 billion in the region. Of the total, $35 billion will take the form of loans, including $15 billion for industrialization and $20 billion as a fund for the United Arab Emirates and Qatar.

FS to support Iranian high-speed projects
Wednesday, April 13, 2016



ITALIAN State Railways (FS) will participate in the construction of the Teheran - Hamedan and Qom - Arak high-speed lines under a framework agreement with an estimated value of around €3bn, which was signed in Tehran on April 12 by FS CEO Mr Renato Mazzoncini and Dr Mohsen Pour Seyed Aghaei, Iran's deputy transport minister and president of Iranian Islamic Republic Railways (RAI)

Under the agreement, which builds on a memorandum of understanding signed by the two parties on February 9, FS will act as a general contractor providing services to RAI through the design, construction, testing and commissioning phases of the two projects

Iran appoints high-speed rail consultant
Thursday, December 15, 2016



IRANIAN Islamic Republic Railways (RAI) has awarded Italferr, the engineering subsidiary of Italian State Railways (FS), a contract worth around €12m to provide project management consultancy (PMC) services for the development of Iran’s first high-speed line

The 415km Tehran - Qom - Isfahan line will have a design speed of at least 250km/h

Italferr will (and already does) provide consultancy for the high speed line. It seems that Chinese companies should complete the line which looks built to around 60%. The problem seems to be that Iranian actors have no clear idea on how to complete the line, and the Chinese are those who will build, but not plan the line.
In fact, at both ends of the current line, Qom and Isfahan, they have no clue where to build the stations.
Italferr provides a detailed analysis, suggesting for example not to remove the current central station in Qom to the desert ...
