The double-track line connects to a length of 117 km, the capital city of Beijing ( South Station ) to the port city of Tianjin. It is configured for an operating speed of 300 km / hr. The Routing allows speeds of up to 350 km / h

The route runs parallel to the route of the new high-speed Beijing- Shanghai.

History

The design speed of the line in 2006 was 350 km / h, the train service should be handled with a top speed of 300 km / hr. The proposed planning and construction period was 27 months. The construction costs were ( 2.9 billion U.S. dollars) to 14.3 billion yuan.

In March 2008, the first test drives took place. On 24 June 2008, against 8:55 clock, presented a CRH3 on the track doing with 394.3 km / h new speed record for rail vehicles in China. The tests at the track, which included a total of more than 100,000 kilometers, was completed on 30 June 2008.

The handover took place as planned on 1 August 2008, a week before the start of the 2008 Summer Olympic Games in Beijing. Compared to the previous track, the travel time of 70 reduced to around 30 minutes. In addition, free with the new line capacity on the existing line.

Since August 2, 2008, at 47 trains per day in each direction. For the first time in the world a speed of 350 km / h is reached on schedule in regular operation with passengers. The minimum travel time non-stop service on the 115- km stretch lies at around 20 minutes. Since then run five CRH3 with the planned top speed of up to 350 km / h and six CRH2 - Multiple Units in passenger service. Along the way there are five railway stations. The current total of ten trains in the 10 - to 20 -minute intervals and each need 30 minutes for the whole route.

By mid-2009 more than 13 million passengers used the route, an average of 40,000 per day, with peaks of up to 80,000 people. 70 trains per day in each direction (as of August 2008), with a minimum headway of five minutes that can be lowered if necessary to three minutes.

Technology

Comes on the track for the first time in the People's Republic of China, ETCS (Level 1) as a train protection system used.

On the route comes to approximately 100 km in length a slab track ( Bögl system ) are used.
