GAP of curved platforms in the Barcelona metro network

Ferrocarril Metropolità de Barcelona, SA

TMB is the main public transport operating company in the Barcelona metropolitan area. Transports Metropolitans de Barcelona (TMB) is the common name of the companies Ferrocarril Metropolità de Barcelona S.A (FMB) and Transports de Barcelona (TB) S.A, which manage the metro and bus network on behalf of the Barcelona Metropolitan Area. It also includes the companies Proyectos y Servicios de Movilidad, SA, Transports Metropolitans de Barcelona, SL, as well as the TMB Foundation.

The Ferrocarril Metropolità de Barcelona, S.A is the company of the Group that prepares the accounts consolidated annually.

TMB has 106 bus lines and 11 metro lines with a length of 946 km. In 2022, Transportes de Barcelona SA (Bus) had a demand of 178.11 million users, while Ferrocarril Metropolità de Barcelona SA (Metro) had 371.68 million passengers. The Barcelona Bus Turístic service has had 2.95 million trips and the Montjuïc Cable Car has had 1.53 million trips.


TMB provides services in Barcelona and in 10 other municipalities in its metropolitan area. It is the main public transport operator in Catalonia.
The Barcelona metro network has eight lines (five conventional lines and three automatic) and also includes the Montjuïc Funicular in its service. In total, there are 165 stations and 165 trains running at rush hour.

With extensive service hours, the TMB metro network is currently used by more than 400 million passengers a year, 39% of all passengers in the metropolitan region. Currently, in the Barcelona Metro network there are 9 stations with platforms built on a curve.

Due to the curvature of the platforms, a series of problems have been generated: accidents, injuries, problems in boarding and disembarking users, increased time to access the metro, availability of accompanying personnel who offer help to users, etc.

At this time we cannot accurately determine the approximate number of users who cannot use the service due to accessibility problems, but we can specify the population data of people with disabilities and people over 65 years old residing in the municipalities served by TMB, who are potential users, as detailed in the following image:

The current solution is to have specialized personnel to facilitate access to the metro.

Currently, in the Barcelona Metro network there are 9 stations with platforms built on a curve. This arrangement generates a Gap (space between the platform and the train abutment) that exceeds 30 mm measured vertically and 75 mm measured horizontally. This space makes it difficult for all users to access the train, as can be seen in the photographs.
