Platform Screen Doors - Articles and news items
Miryam Hernández from the International Association of Public Transport (UITP) asks whether platform screen doors are the system of choice when considering platform/track protection systems.
A number of underground networks worldwide are gradually installing screen doors at the edge of their platforms to prevent passengers from falling onto the tracks. The first platform screen doors to appear in Paris were those used for the VAL line built to serve Orly airport. These were followed by those on Metro line 14; both of these lines are fully automated.
The automation currently underway on Paris Metro line 1 is the first time screen doors have been installed on an existing line. In all cases, platform screen doors are used to ensure that the system remains impervious to intrusions – a function previously incumbent on train drivers.
Several metro networks are progressively introducing platform screen doors, set-up at the edge of platforms to prevent passengers falling on the tracks. Platform screens remove the risk of accidental falls and prevent suicide attempts. Platform screens also improve the general sense of safety of the passengers waiting at platforms. In addition, they contribute to improving the regularity of train movements by shortening waiting times.
On the Paris network, platform screens are regarded as indispensable on lines that are automated (Line 14 was equipped at the outset and the current automation of Line 1 includes the fitting of platform screens). On non-automated lines, platform screens bring advantages in terms of safety, regularity and comfort.
Platform Screen Doors (PSDs) offer many advantages to rail and metro operators including increased safety, comfort for passengers, and added aesthetic appeal. This is why they are increasingly being ordered by transport operators across the world.
The most obvious benefit is that PSDs act as a physical barrier preventing people or objects from falling or trespassing onto the tracks. This helps prevent suicides, reduces the risk of accidents (especially when trains pass though the station at speed) and stops people entering tunnels.
