Barcelona Automated Line 9/10

The construction of the 9/10 line began in 2002, but was delayed due to financial problems and should be completed in 2019. The project cost is 6.5 billion euros.

Line 9/10 has a north-south direction and runs west of the historic center of Barcelona. In the north, the line goes to the suburbs and to the new La Sagrera station of the high-speed line Barcelona - Madrid, in the south - to the airport and seaport. 17 of 52 stations have connections to other Barcelona metro lines. A number of important passenger flow generation facilities are located on the line - the airport and the port and logistics zone, the Supreme Court, the high-speed La Sagrera station, Barcelona University and the Polytechnic University of Catalonia, the Fira de Barcelona Exhibition Center, São Pau Hospital and Camp Stadium Know . "

In 2017, there are two branches running northward from Bon Pastor Station - to Kan-Zam Station (line 9) and to Gorg Station (line 10), launched in 2009 and 2010. Between the stations of Bon Pastor and La Sagrera, both lines run along the same common section. The northern section is 11 km long and has 12 stations. In the south, in February 2016, a section was opened from the Zona Universitaria station to the airport (line 9) with a length of 19.6 km with 15 stations. Trains run at intervals of 7 minutes, travel time is 32 minutes. Line 10 also completed the construction of a southern section of 5.9 km, ending in a depot. A tunnel of about 5 km has not yet been completed on a central section of 11 km in length, as a result of which the southern and northern segments of the line are not connected.

At least 36 stations out of 52 are deep-lying stations and are located at a depth of up to 90 m. The use of escalators to descend to such deep stations is considered irrational. Instead of escalators, high-speed high-capacity elevators were installed, at least 6 at each station, all of them are built into a single shaft shaft with a diameter of 28 m. Some of the passenger platforms are located in the tunnel with a diameter of 12 m one above the other. For emergency situations, staircases are built.

On line 9/10 there is a radio traffic control system for trains (CBTS, TETRA standard) and a signaling system supplied by Siemens . This system provides the mode of movement of metro trains without drivers, in 2017 it is the most efficient and reliable of the existing systems, has the highest level of automation of GoA 4 train control. Sliding doors open and close synchronously with the train doors, which completely eliminates the risk of passengers falling from the platform . The movement of trains and the situation at the stations are monitored from the main control center of the Center de Control de Metro de Barcelona, ​​CCM and the emergency coordination center, the operation of both centers is synchronized. Physical and logical integration of all subsystems is also provided. Practice confirms that any deviations from the standard situation always attract the attention of staff and cause an adequate response.

On line 9/10, technology is used to remotely control trains, facilities and infrastructure, resources, elevators, escalators, ticket machines and turnstiles. Trains run at a given speed and according to established schedules, which can vary depending on passenger traffic and other changing circumstances. The network monitoring center, the control center has the ability to intervene at any time.

The need for personnel on automated lines is much less than on conventional; the hierarchical structure of subordination is no longer necessary. The principle of rotation of staff responsibilities applies, from inspections of stations and trains to work in a depot or control center. The usual boundaries between the duties of workers are erased, everyone has equal rights, each specialist becomes interchangeable, employees get rid of the need to repeat the same routine operations, which increases labor productivity. The automated metro implements the concept of mobile personnel, implying that the location of each employee is monitored by the center, and the employee himself can appear in the facility where his presence is currently required, usually at the busiest stations during the hours , from 8 to 12 minutes peak .

The operational experience of the line 9/10 of the Barcelona metro (as well as all local lines without drivers) confirms that automation using sophisticated modern monitoring and control systems for trains is a means of improving the quality of passenger service. This increases the technical safety, accuracy and reliability of the subway, the throughput of the line and the speed of trains (especially during peak hours), reduces the likelihood of errors due to the human factor. According to experts, the implementation of the 9/10 line project makes Barcelona a transnational reference example in the field of metro automation - both on lines under construction and during the conversion of existing ones ^[1] .
