Barcelona metro tests vertical platform screen doors

Barcelona Metro trials a set of vertical platform screen doors, an innovative solution to improve passenger safety and comfort and, at the same time, enhance the safety and regularity of train traffic. The city’s metro has become the first in the world to put into operation such innovative solution.
The pilot test, started in May, is a result of a collaboration between the local public operator TMB and a consortium of companies and technological institutions from South Korea headed up by STraffic. It had been put into operation on one of the platforms of the Can Cuiàs station, on Line 11, located in the metropolitan area. The trials at Can Cuiàs are the first ones for an automatic vertical door system on an urban metro network given that, up until now, they have only been installed on some suburban lines in Asia.
On the platform chosen for the test, which is not usually used for passenger traffic, two vertical automatic door modules have been installed by STraffic. Successive operational reliability and integration tests will be performed on this equipment for at least six months and, if the results are favourable, tests will continue on their commercial operation with passengers. The series 500 trains used on Line 11 that are involved in the tests are composed of two carriages with a capacity of about 300 people.
The vertical platform screen doors (VPSD) represent an alternative to platform doors that open horizontally and which are already installed on many automated lines, including Line 9/10 and 11 of the Barcelona metro. They consist of a fixed vertical structure with guides where two transparent rigid panels slide up and down in a similar way to a window blind. They come down to form a physical barrier about 160 centimetres high between the train and the edge of the platform, and they fold upwards to let passengers on and off the train. They are designed to work automatically, synchronised with the passing of trains.
Compared to horizontal sliding doors, the vertical ones offer the advantage of providing much broader access spaces of over 7 metres, meaning that it is not necessary for trains to make highly precise stops nor for them to have exactly the same distribution of doors. For that reason they are appropriate for a wide variety of line systems, even those that combine trains of a different series as is the case on some of Barcelona’s metro lines.
In addition, the vertical doors are quicker and easier to install compared with horizontal doors, there is less need for structural reinforcement and less impact on traffic flow during their installation. Maintenance costs are lower due to their having fewer mechanical parts.
