The Beijing–Tianjin Intercity Railway (simplified Chinese: 京津城际铁路traditional Chinese: 京津城際鐵路pinyin: Jīng-Jīn chéngjì tiělù) is a 117 km high-speed rail line between Beijing and Tianjin in China. It was put into service on August 1, 2008 with a maximum design speed of 350 km/h (217 mph) and CRH trains running on the line at a top speed of 330 km/h (205 mph) are the fastest conventional trains in the world.[1][2] The 120 km journey between Beijing and Tianjin, a city co-hosting football matches at the 2008 Beijing Olympics, was shortened from the original 70 minutes to 30 minutes.

Service

Since August 1, 2008, 47 daily pairs of trains services have run between Beijing South and Tianjin, of which, six pairs run between Beijing South and Tanggu (they only run between Beijing and TIanjin currently) on the seaside near Tianjin. In addition 13 pairs of existing trains were switched to the new line instead of existing Jinghu railway, including trains from Beijing South to Jinan, Qingdao, Shanghai, and Tianjin West. A pair of special track examination train (numbered DJ01/02) run every day in the morning before any regular trains into service. A track-measuring train (numbered DJ5581/2) runs every ten days. In summary, there are 62 pairs of train in service, 60 of them for passengers.

Since September 14, 2008, 10 more pairs of trains were added, reducing the minimum interval from 15 minutes to 10 minutes.

On September 24, 2008, 4 pairs of trains extended to Tanggu.

On September 28, 2008, 2 more pairs of trains were added into service.

In its first year, the line carried 18.7 million passengers, 86% more than the number of rail passengers between the two cities the previous year.[3] The opening of the line is also credited with a 30% fall in the number of passengers carried by intercity buses.[4]

Trains

The ticket looks a bit different from train tickets usually found in China

CRH2C (300 km/h, overspeed up to 350 km/h on the line) and CRH3C (350 km/h) EMU trains are used for the route from Beijing South to Tianjin. 8 trains will be in service and 5 of them are CRH2C (CRH2-062C, 063C, 064C, 065C, 066C) and 3 are CRH3C (CRH3-001C, 005C, 006C). For longer distance trains from Beijing South to Jinan, Qingdao, Shanghai and Tianjin West, slower CRH2A (200 km/h, overspeed to 250 km/h on the line) are used as before.

The intercity train number is prefixed with "C" (城) followed with four digits, from C2001 to C2298. Of these train numbers, C2001–C2198 are for trains traveling from Beijing South to Tianjin without stopping, odd numbers for train departing from Beijing South and even numbers for those running towards Beijing South. Trains numbered C2201–C2268 are trains from Beijing South and Tianjin that stop at on the way at Wuqing and Yizhuang stations. C2271–C2298 are trains from Beijing South to Tanggu. Existing Jinghu (Beijing-Shanghai) line trains use the D prefix as before.

Tickets

First and second class passengers receive bottles of water, while deluxe-class passengers receive Wang Lao Ji herbal tea.

Three classes of tickets have been introduced with fares higher than the former Beijing-Tianjin ticket fares: the deluxe seat (8 seats only available on CRH3s near the tail of trains) costs ¥99 (about €10 or $15 US), a first class seat costs ¥69 (about €7 or $10 US), while second class costs ¥58 (€6, $8 US).

Line & Technical information

The line has a total length of 113.544 kilometers, of which roughly 100 km is built on viaducts and the last 17 kilometres on an embankment. The elevated design was chosen due to the flat surface the line crosses. The total cost was roughly 14.3 billion Renminbi (Around $2 Billion US).[5]

The line is the first railway in China to be built for 300+ km/h running, and the alignment is designed to ultimately permit 350 km/h.[5] A trip between Beijing and Tianjin will take 30 minutes.[6]

Signaling system

The signaling system is built around Simis W electronic interlockings, Vicos operations control system and ETCS Level 1 train control system.[7]

Overhead catenary system

The caternary system in use is Sicat HA, aluminum cantilever,[7] electrified by two sub-stations at 25kV 50Hz AC.

History

Construction began on July 4, 2005, and the line opened on August 1, 2008.

In April 2006, Siemens and its consortium partners EEB (Electrification Engineering Bureau) and CRSC (China National Railway Signal & Communication Corporation) were awarded a contract by the Chinese Ministry of Railways (MoR) to supply and install the signaling systems, communications equipment and power supplies as well as the overhead line and to take over responsibility for system integration and overall project management.[7]

On May 11, 2007 the first interlocking container for the Beijing-Tianjin line left the Siemens factory in Brunswick, Germany. (This container had been the 1000th container shipped from the factory overall).[8]

Speed record

On June 24, 2008 a new Chinese steel-wheel rail speed record was set on the line when a Siemens Velaro-derived China Railways CRH3 train reached 394.3 km/h.[6]

Stations

The line has two terminal stations at Beijing South and Tianjin and three intermediate stations at Yizhuang, Yongle and Wuqing.
