Why do class 700s have an interior partition

[NaZzAtAzEr]

I often see this partition on one of the carriages and it looks like a sliding door. What is it and why is it there?

Isn't that a fire door to enable the passengers to be transferred to the 'non-burning' side of the door?

Believe it's one of four 'fire partitions', used in the event of an on-board fire to enable it to be contained in one section - with passengers obviously moved to other unaffected sections.

As previously said they are partition doors. Can be used in the event of a fire/smoke event.
Also can be used for a variety of other uses that can keep a unit in service instead of being cancelled.

Which is why sometimes you see this train is formed of 5 or 9 coaches on passenger information screens.

Thanks peeps, never seen this stock short formed!

Anyone got a picture of it closed?

Do the other modern wall-through MU classes have these kind of partitions too?

Happens very rarely, but I did use one a few weeks back.
Someone had vomitted all over coach 11, instead of pulling the unit out of service. We closed these doors and the train could continue short formed to it's destination, and ultimately the depot for cleaning.

That’s interesting. I’ve literally never seen one being used. Are there any pictures floating around of them deployed?

(To echo the similar request above!).

So other Aventras might too, i'll have a closer look next time on a local 730.
