A couple of years ago, plans were shown off for trains with inflatable seats. Today, it’s all over the news for some reason.

The Air Train concept was created by the Japanese architectural design firm Nikken Sekkei and the engineering firm Arup back in 2014 as part of a wider call for concepts that could be part of a next-generation train.

The idea was to essentially cover the inside of a train in a rubber sheet, and when the trains were less busy, the bottom section would inflate to form seating, which could then collapse down when the trains were busy.

In essence, it’s no different from replacing fixed seating with fold-up seats — but in a way that makes the seats inoperable during rush-hours.

But rather than design lockable fold-up seats, Arap covered the entire train in rubber and then made the seats inflate when needed. They claim that this can release 40% extra capacity in the carriage during rush hours.

Unsurprisingly, it wasn’t shortlisted for further development, so, no, the news reports are wrong to say this is a possible future of train interiors.

Not just because the idea is frankly, bonkers — but the public want to sit down on seats — and forcing them to stand would have caused a most unpleasant reaction, even on short commuter hops, let along longer journeys.

The call for improvements to the design of train interiors though, bouncy castles aside, was a serious one, and a number of concepts were suggested.

Most of them worked on how to fit more seating into trains, or to make the seating options more flexible to avoid space wastage.

Long term, the issue is about reducing the space taken up by the fabric of the train shell, so that more space can be extracted from of the carriage to allow more seats to be provided.

Which is in part why double-decker trains are being looked at again.

But not inflatable rubber seating.

This website has been running now for just over a decade, and while advertising revenue contributes to funding the website, but doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether its a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

    I wouldn’t want to be sitting on one when it retracted.

    Also, it’s like adding an even more in-your-face “cattle mode” to trains.

    Arup not Arap. Just sayin’. & yes, rubbish concept.

    the trains on the Denentoshi line in Tokyo already have flip up seats that are raised during rush hours to make extra space in the carriages

    they work very well.
