Shall we abide by the definitions used by Wikipedia? And yes, I agree that a numbering system is more useful than annoying ordinary passengers with the technical differences between the 2 lines in operation. But there is no reason why people discussing metro systems in a forum should be forced to ignore the differences between the techology.

Quoting Wikipedia:

"Light rail or light rail transit (LRT) is a form of urban rail public transportation that generally has a lower capacity and lower speed than heavy rail and metro systems, but higher capacity and higher speed than street-running tram systems. The term is typically used to refer to rail systems with rapid transit-style features that usually use electric rail cars[1] operating mostly in private rights-of-way separated from other traffic but sometimes, if necessary, mixed with other traffic in city streets. Modern light rail technology is highly flexible in how it can be used, and whether any given system is considered a true rapid transit system or not depends on its implementation. [2][3][4]

Definition of light rail
See also: Passenger rail terminology

The term light rail was devised in 1972 by the U.S. Urban Mass Transportation Administration (UMTA) to describe new streetcar transformations which were taking place in Europe and the United States. In Germany the term Stadtbahn (to be distinguished from S-Bahn which stands for Stadtschnellbahn) was used to describe the concept, and many in the UMTA (now called the Federal Transportation Administration) wanted to adopt the direct translation, which is city rail. However, the UMTA finally adopted the term light rail instead.[5] Light in this context is used in the sense of "intended for light loads and fast movement", rather than referring to physical weight, since the vehicles often weigh more than those on so-called heavy rail systems. The investment in infrastructure is also usually lighter than would be found for a heavy rail system.

The American Public Transportation Association (APTA) in its Glossary of Transit Terminology defines light rail as: "An electric railway with a 'light volume' traffic capacity compared to heavy rail. Light rail may use shared or exclusive rights-of-way, high or low platform loading and multi-car trains or single cars."

Light metro
For more details on this topic, see Medium capacity system.

A derivative of LRT is light rail rapid transit (LRRT), also referred to as Light Metro. Such railways are characterized by exclusive rights of way, advanced train control systems, short headway capability, and floor level boarding. These systems approach the passenger capacity of full metro systems, but can be cheaper to construct by using the ability of LRVs to turn tighter curves and climb steeper grades than standard RRT vehicles."

On the Asian side, the branch from Kadıköy to Kartal will, as far as I know, add about 22 km to the system once it's finished in 3-4 years' time. That's 77 km combined. You're not telling us they'll build another 420 km of metro line between 2012 and 2023???

One of the suburban trains, locally called banliyö (from banlieu), presently operating on inner-Istanbul lines. They are Alstom from the 1960s, if I am not mistaken. They will disappear by next year when the entire network is closed down to upgrade the lines before being connected to the tunnel you see in the photos as u/c. When the lines reopen, only the new Marmaray (CAF?) train sets you see in one of the older posts will be used.


PS - Marmaray is perhaps not the most catchy name for this thread. There should be some hint to the fact that it is in Istanbul. Also we have been discussing Istanbul metro lines in the framework of this thread, so Istanbul Public Transport or so would be more appropriate.

People who know where Istambul is - do know also, what's Marmaray

You are right of course, Arda: Hyundai Rotem, like our present Taksim metros (and unfortunately the interior design looks just as bleak as on M1 too - long sterile benches against the wall instead of seat groups of 4 like the Ankara suburban rail). CAF will be used on the new metro from Kadiköy.

Almost finished metros, current official dates

In an interview with Dursun Balcioglu, deputy head of Transport Det. at the Istanbul Municpality, we are given once again official dates for the Istanbul metro lines almost finished. (see rayturk for this) Many are not exactly new, but I find it worth summing up for sake of non-Turkish readers and so we can later once again say "I told you it wouldn't work."

Metrobus Avcilar-Tüyap extension: June 2012
M4 Kadiköy-Kartal: late June or early July 2012
M5 Kirazli-Basaksehir/Olympic stadium: late July or early August 2012
M3 Esenler-Kirazli:end of 2013
M2 Sishane-Yenikapi extension: end of 2013 (?)
Marmaray Sögütlücesme-Kazlicesme: end of 2013
Marmaray Halkali-Gebze: end of 2015
No concrete statements on Kartal-Kaynarca and Üsküdar - Ümraniye, which to my knowledge are officially u/c and according to previous statements should become operable in 2015 and 2016 respectively.
Balcioglu seemed to be rather reserved on the topic of Yenikapi-Sishane, which when summing up all lines which should be operable at the end of 2013, he did not include in the list. I think the municipality is aware that because of the long delays in many places, it will be later that this line makes it down to the Marmara. As for the others, let us keep our fingers crossed.

Connecting continents amid archaeology and earthquakes

The Gateway goes behind the scenes of the world's major transport hubs, revealing the logistics that keep goods and people moving. This month, the show is in Istanbul, Turkey.

Istanbul, Turkey (CNN) -- As a city that sits astride two continents, Istanbul has always been a strategic gateway between the East and West. But an ambitious railway project is pulling the two continents even closer together with the construction of the world's deepest submerged tunnel.
The 76-kilometer (47.2-mile) Marmaray Project will include the world's first submerged railway connection between Europe and Asia, ferrying passengers under a 1.4-km (0.9-m) section of the Bosphorus Strait.
However, the massive infrastructure overhaul undertaken by Turkey's Ministry of Transportation has not been without problems. The project started in 2004 and has suffered multiple setbacks due to the region's rich heritage, as Turkey's transport minister Binali Yildirim explains.

"The tunnel is going under a very historical area, [a] historical peninsula where the Ottoman Empire settled ... so every piece of soil is examined by experts, archaeologists." Yildirim said.
At one point during construction, work had to be halted after the discovery of an ancient Byzantine port.
"If [the archaeologists] say you can go, we go. If they stay stop, we stop," Yildrim said.
All of which has added five years onto the original construction deadline.

To complicate matters further, the tunnel -- which passes under one of the busiest waterways in the world -- lies in an active earthquake zone.

"There is a big, huge seismic activity risk so we have seismic joints in the tunnels, especially between the immersed tube tunnel and the bore tunnel," says deputy project manager, Mehmet Cilingir.
The joints between the tunnels are flexible and will protect the structure from seismic movements, Cilingir says.
Despite the setbacks, the project is scheduled for completion next year -- a target that will be met, Yildirim says.
"We are very comfortable that the project is going to be complete by the end of next year. 14 million people are just waiting [for this tunnel to open."]
When it does, the tunnel is expected to ease the congested road and ferry routes above carrying 75,000 passengers per hour in each direction at peak times.
Train drivers, like Mustafa Berker, are already getting to grips with the new trains that will operate on the line.
"It will be a great joy for me if I too can add a bit to this big project," says Berker, a driver with almost four decades experience.
"I'm ready for my retirement but if I can see this through, it will be a great pleasure both for me, my children and grandchildren."
