M3 metro: special elements to reduce the clearance between trains and platforms

In our newspaper, we followed the reconstruction of the M3 underground line in a special section. Following the official handover of the last two stations, the entire line opened to passengers on 22 May 2023. During the works, which began in November 2017, the entire metro line was renovated by SWIETELSKY Építő, the rel="noopener">SWIETELSKY Építő, Swietelsky Vasúttechnika and Strabag.

In 2022, we already reported that a new solution was being tested on the M3 metro line to promote barrier-free transport. To reduce the gap between the platform and the trains, so-called platform gap fillers (PGF) are being attached to the platform.

The problem of the excessive distance of 5-6 centimetres between platforms and trains has been highlighted by the National Association of Societies of People with Disabilities (MEOSZ), which has pointed out that it is unsafe for wheelchair users. BKV sought a solution to this problem and decided to install PGF elements at stations on the M3 metro line.

Our photos show the work being done, and a video on the subject is also available on the BKV Zrt. Metro Renovation Project Management website.

Installation was carried out during the night shutdown

PGF element is a strong rubber platform fitting that minimises the clearance between the platform edge and the edge of the train door. It is flexible and therefore does not cause damage to the subway train, while at the same time withstanding the stresses caused by passenger traffic, ensuring easier boarding and alighting.

The test period has been successfully completed and in June 2023, the PGF elements will be installed at all stations on the M3 line between Kőbánya-Kispest and Újpest-Központ. The stations at Deák Ferenc tér, Ferenciek tere, Kálvin tér and Corvin-negyed were worked on.

Our photographer had the chance to see the works at Deák Ferenc Square, and we show you exclusive footage of the installation process.

The panels were installed at four doors per station, each 5 metres long; 10 half-metre panels were installed per door. Accessible entry and exit is indicated by platform signs.

The installation work was carried out from the station's track space, so that the technicians could only work at night, during the de-energised period. After the work was completed, a train was used to check the success of the installation.
