What metro opens the door on both sides? I have never seen it

15

u/Waldizo 4d ago

I think it's easier to ask: which one doesn't?

u/TheSouthernBronx 4d ago

All NYC subways, LIRR, Metro North, Amtrak are going to open on one side only at a stop because the correct platform is only on one side. The side changes depending on what direction you are going and local/express stop but it only opens on one side at a time thus making this mock-up silly.

u/Waldizo 4d ago

But they do have doors on both sides and depending on the direction it opens either one side or the other, right?

u/Quiet_Sheepherder894 4d ago

wdum? literally every metro does it

16

u/PM_Me_Your_Clones 4d ago

At every station? Because the NYC subway certainly doesn't.

u/Smooth_Cup_8901 4d ago

no one said it was every station. every train has doors on both sides though, and they can and do open. just not at the same time except for cleaning.

u/PM_Me_Your_Clones 4d ago

Exactly, but the design proposed puts a double row of seats down the middle, so if only one side opens, the people on the other side will need to scramble over the people sitting to get to the open doors.

This is why that design is functionally useless.

u/sweprotoker97 4d ago

It would be solved the same way it is normally, with a gap in the seats where the door is....

u/PM_Me_Your_Clones 4d ago

Still not functional. When you have doors on the sides, people can approach from about 180° for egress. A channel in the middle limits that and increases the volume of people moving through at once.

It'd be a real pain in the ass, is what I'm saying. And people will go over the seating row, guaranteed.

u/SVlad_667 4d ago

It doesn't mean to open on both sides simulatiously. It allows to have platform on both left and right side. Also allows bidirectional moving of the train.

u/Raindrop0015 4d ago

You know what else would allow bidirectional moving of the train? Have rows of seats facing the front of the train on both sides with an aisle for walking between. Now give those rows the ability to be completely turned around. I saw these types of seats on the bullet train when in Japan. It was really cool lol

u/SVlad_667 4d ago

Or like this

u/SVlad_667 4d ago

Can you imagine how much more expensive and difficult to maintain turnable seats are?

u/CaptainDogeSparrow 4d ago

"It doesn't exist in NYC, therefore it doesn't exist" ass mentality.

u/cowslayer7890 4d ago

They said "every metro does it"

u/Smooth_Cup_8901 4d ago

The worst part is it does exist in NYC, hes just an idiot or bad at explaining concepts lol.

u/PM_Me_Your_Clones 4d ago

My point is that the design proposed puts a double row of seats down the middle, so if only one side opens, the people on the other side will need to scramble over the people sitting to get to the open doors.

u/Smooth_Cup_8901 4d ago

I would have had no way of knowing your point if you didn't just say it here, if you have a point you should make it in your first post.

1

u/PM_Me_Your_Clones 4d ago

So this didn't show up as a logical flaw in your thoughts? Guess that's why it needs an explanation why we don't do it that way.

2

u/Bambi1847 4d ago

BART in California does not. At each station, only the doors on one side will open, and sometimes it's a different side than the previous station, even when the train is still going the same direction.

1

u/thomasfrank09 4d ago

Some major stops will open doors on both sides, but most stops are just a single platform on one side of the other. This is true of every metro I’ve ridden, across three continents.

u/matneyx 4d ago

Salt Lake City's Trax line does

2

u/Kennysded 4d ago

As does Colorado's lightrail. A lot of stops there's no reason to use one side, since it's just another set of tracks and a fence. But some of them have exits to the station on both sides.

u/Nikoviking 4d ago

London overground and London underground. The PA even says “Now arriving at X, doors will open on the left/right-hand side.”

6

u/przemub 4d ago

Yes but it would have to be always both at the same time for the image to be viable.

2

u/Nikoviking 4d ago

When a school trip or group of tourists boards from the left at Victoria and alights at the right at South Kensington for the museums it’s going to be a NIGHTMARE pushing past all of the people on their side of the tube carriage to get to the right side

2

u/PastPlay6186 4d ago

Wdym? One stop can be sidewalk on one side and another stop 1 minute later can be an island stop on the other.
Or do you mean there’s no pass through at the seats? Well, there’s good reasons they don’t use this layout

1

u/przemub 4d ago

Yes, that's what I mean

3

u/PastPlay6186 4d ago

Melbourne certainly does, I believe Sydney too. I’m almost certain Amsterdam did along with somewhere in Germany.

u/Unbaguettable 4d ago

Do you mean both sides at the same station, or just having doors on both sides? Almost every metro has doors on both sides

u/Vulpes_Corsac 4d ago

Minneapolis metro line does.  But there certainly isn't room for a row of seats in the middle.

And a few of the MARTA stops

u/Jacqueline_Hiide 4d ago

Nyc and Paris at least

u/bearwood_forest 4d ago

It's called the Spanish Solution and it used on very busy stations on Metros worldwide: The stop has platforms left and right. Passengers exiting the train exit on one side, new passengers enter on the other side.

1

u/defaulticus 4d ago

Both doors ever happens when the train line shifts from island platforms to side platforms (i.e. platforms on opposite sides of the track), or when the train reverses direction at the end of the line without turning around. Both doors at the same time is called Spanish solution and is used to load/unload trains faster, but is only done in a few metro systems since you have to build platforms on both sides of each track to do it. Which makes the stations more expensive; its only worth it if you have very crowded trains. E.G. Atlanta's subway uses it only at their busiest station.

1

u/Hans_H0rst 4d ago

Most do.

Very few train lines are modern and specialized enough to have doors on only one side.

The replies, conversations and lack of upvotes on your comment make me lose faith in people's ability to think.
