I guess this justifies why we can put platform screen doors on commuter trains

[@VinceHere98]

NYC could use something like this.

[@exp3rtsgaminglawandmusicvideos]

The PSDs forgot to close before the train moves

[@KotaruKun91]

They need some work. Only descend after the train starts moving.

I guess it's to prevent people from getting smashed by the gates when they decend? like when the train leaves no one's gonna stay in that area

@@KotaruKun91 They wanted to, but we have too many different trains with different door placements (except on line A). Also, it would mean changing all doors on all stations every time we need to change or update train designs or tying all future trains with the same door placement design (preventing designs from evolving). We're talking really long term investments here. And trains are not precise enough when stopping, especially in outdoor stations thus making it difficult for passengers to board (they could solve that by making the screen doors extra-large but still a problem).

Why are these doors vertical and not horizontal, it looks ridiculous.

[@stickynorth]

To allow for multiple rolling stock types, MAROON BABOON!

May I use part of this footage in my video? I will give you full credit.

I immediately knew this had to be in France. They like to be unconventional even when it makes no sense!

how does that make no sense

@@burgerpommes2001 The main point of platform screen doors is to improve airflow in a tunnel which isn’t relevant here. The second is to improve customer safety which it somewhat does but remaining open whilst the train is moving isn’t very safe. It also doesn’t stop track trespassing since anyone could just walk to the area past them. Closing top down also seems less safe than normal sliding doors, it just means the trains don’t have to stop so precisely. I do think having these is better than nothing, but it looks like a very expensive system to install for little benefit.

@@morzee94 where did you get the idea that these doors exist for airflow in the tunnels
The only reason that is kid of related that makes sense is that you can install AC in closed stations doesn't make sense on an outdoors stop
The reason platform doors are installed is because it prevents people from falling in front of the train which is provided by these
They can't close at the same time as the train doors because they don't use modern communication technology which is used on metros.
That ties into the reason why they don't use the normal doors
It is a mainline with loads of different door positions

@@burgerpommes2001 When they built the jubilee line extension in London they justified installing them due to the improvement in ventilation, with the obvious safety aspect being a secondary benefit. For crossrail, they also stated that ventilation and smoke extraction was the main reason they were installed. Of course I realise they do improve passenger safety so are good to have, but I don’t think they improve it as much as you might think. Thankfully, people falling onto the tracks accidentally is very rare and for those that unfortunately do it intentionally, they will still be able to do that outside of the station. If they had a huge safety advantage, surely they would be mandatory everywhere?

@@morzee94 the jubilee line ones don't go all the way to the roof so I have no idea how they would have an impact on ventilation
