Çin'le Amerika Arasında Bir Hızlı Tren Mi?

Amerika Birleşik Devletleri'ni Çin'e bağlayan demiryoluyla saatte 350 km hız yapan trenle iki günlük seyahat!

Bu Çinli mühendislerin üzerinde çalıştıkları uçuk bir proje.

Mayıs ayı başlarında konuyla ilgili Çin resmi iletişim kurumu projenin üzerindeki perdeyi kaldırdığını İngiliz The Guardian gazetesi yazdı.

Toplam olarak 13 bin km.lik demir yolu Kanada bağlantısı ile Amerika'ya ulaşmadan önce Çin'in kuzeyinden başlayıp Pasifik Okyanusu'nu aşmadan önce Sibirya'dan geçecek.

İnanılması zor bu proje Trans-Sibirya'nın ( 9 bin km civarında olduğu...) önünde dünyanın en uzun demiryolu olma ünvanını elde edecek ve tabii ki 200 km uzunluğunda iki kıtayı birbirine bağlayacak dünyanın en uzun tünelini inşa etmek gerekecek.

Başka büyük projeler de var!

Kıyaslama yaparsak, Manş Tüneli 37 km.Pasifikte yapılacak tünel Manş ile kıyaslanmayacak ölçüde devasa dünyanın en uzun tüneli olacak. Japonya'daki dünya rekorunu elinde bulunduran 53 km.lik Seikan Tüneli'nden 4 kat daha uzun bir tünel sözkonusu.

Bununla birlikte Pekin'e inanılırsa, bu eserin gerçekleştirilmesi çok fantezi değildir.

Çin Mühendislik Akedemisi üyesi Wang Mengshu, Beijing Times günlük gazetesinde bu demiryolu projesi fikri, deli saçması bir rüyanın bile çok daha ötesindedir diye açıklıyor. Ve diyor ki, " Bugünlerde  bu konuyla ilgili  devam etmekte olan tartışmalarımız var.Zaten Rusya da yıllardan beri bu projenin gerçekleştirilmesini istemektedir"

Un train entre la Chine et les États-unis ?

Deux jours de voyage à 350km/h, c'est le temps qu'il faudrait pour relier la Chine aux Etats-Unis, en train. C'est aussi le projet totalement fou sur lequel travailleraient des ingénieurs chinois selon la presse locale. Les organes de communication officiels ont dévoilé l'information début mai, rapporte le journal anglais The Guardian.

Au total, 13.000 km de voie ferrée partiraient du Nord-est de la Chine, passeraient par la Sibérie pour traverser l'océan Pacifique avant d'atteindre les Etats-Unis, via le Canada. Un projet incroyable qui deviendrait le plus long chemin de fer au monde, loin devant le Transsibérien (qui ne mesure qu'à peine plus de... 9000km), et qui nécessiterait le plus long tunnel mondial pour rejoindre les deux continents (200km).

D'autres projets de grande ampleur!

En comparaison, le tunnel sous la Manche est sous-marin pendant 37km. Le tunnel sous le Pacifique deviendrait donc -et de très loin- le tunnel le plus long au monde, la portion sous-marine étant quatre fois plus longue à elle seule que le tunnel du Seikan (Japon), 53km et actuel détenteur du record.

Pourtant, la réalisation de l'ouvrage n'est pas si fantaisiste à en croire Pékin. Wang Mengshu, membre de l'Académie chinoise d'ingénierie, explique au Beijing Times que l'idée est bien plus qu'un rêve farfelu: "Actuellement, nous avons déjà des discussions en cours, la Russie envisage ce projet depuis des années."

Chinese experts 'in discussions' over building high-speed Beijing-US railway!

'China-Russia-Canada-America line' would run for 13,000km across Siberia and pass under Bering Strait through 200km tunnel

China is considering plans to build a high-speed railway line to the US, the country's official media reported on Thursday.

The proposed line would begin in north-east China and run up through Siberia, pass through a tunnel underneath the Pacific Ocean then cut through Alaska and Canada to reach the continental US, according to a report in the state-run Beijing Times newspaper.

Crossing the Bering Strait in between Russia and Alaska would require about 200km (125 miles) of undersea tunnel, the paper said, citing Wang Mengshu, a railway expert at the Chinese Academy of Engineering.

"Right now we're already in discussions. Russia has already been thinking about this for many years," Wang said.

The project – nicknamed the "China-Russia-Canada-America" line – would run for 13,000km, about 3,000km further than the Trans-Siberian Railway. The entire trip would take two days, with the train travelling at an average of 350km/h (220mph).

The reported plans leave ample room for skepticism. No other Chinese railway experts have come out in support of the proposed project. Whether the government has consulted Russia, the US or Canada is also unclear. The Bering Strait tunnel alone would require an unprecedented feat of engineering – it would be the world's longest undersea tunnel – four times the length of the Channel Tunnel.

According to the state-run China Daily, the tunnel technology is "already in place" and will be used to build a high-speed railway between the south-east province of Fujian and Taiwan. "The project will be funded and constructed by China," it said. "The details of this project are yet to be finalised."

The Beijing Times listed the China-US line as one of four international high-speed rail projects currently in the works. The first is a line that would run from London via Paris, Berlin, Warsaw, Kiev and Moscow, where it would split into two routes, one of which would run to China through Kazakhstan and the other through eastern Siberia. The second line would begin in the far-western Chinese city of Urumqi and then run through Kazakhstan, Uzbekistan, Turkmenistan, Iran and Turkey to Germany. The third would begin in the south-western city of Kunming and end in Singapore. The routes are under various stages of planning and development, the paper said.

Wang was not immediately available for comment. A man who picked up the phone at his office said he was traveling and would not respond to interview requests."

• This article was amended on Friday 9 May 2014. The project is nicknamed the "China-Russia-Canada-America" line, not the "China-Russia plus America line" as we said first. This has been corrected.
