> It’s fair to say that few of us now marvel at moving walkways, those standard infrastructural elements of such utilitarian spaces as airport terminals, subway stations, and big-box stores.

You've gotta be referring to escalators here. Never seen a moving walkway in a big-box store, or a subway station for that matter.

There are at least some in the Paris subway, including one that went at 12 km/h but was decommissioned in 2011:

		That one was in activity about the same period I took the Montparnasse station somewhat regularly, and over those years I couldn't ever take it as it was always either broken or running opposite to my direction. I do think a concept with parallel tracks moving at different speeds would have been easier to use and more reliable though. But it might not have been revolutionary/over-engineered enough to attract attention and subsidies.

		Man, they should've designed it similarly to the video, with parallel tracks with differing speeds. But people's lack of attention would probably lead them to park a foot on each track and causing a tumble. Speaking of speed, in the Stockholm main station the escalators go faster than others I've experienced... But I don't know if they've adjusted the speed since my experience years ago.

		Decomissioned but still rolling, just slower.

I have seen some occasionally in stores, in or around Paris. They usually are on an incline to allow trolleys to be taken up or down a level. Or similarly outside malls to get trolleys to the upper level of a car park. That’s in places where you have to stack car parks instead of just having them sprawl all over the place, of course.

> or a subway station for that matter.

There are a few of them in Paris métro stations. Some of them in the London Underground, as well.

		There's one in a Target in the LA area. I forget exactly where it is.

There's one in Sydney, from a carpark to near the city centre, of 207m.

Quoting wikipedia:

> The walkway has been the longest continuous moving walkway in the world since its construction in 1961.

Notwithstanding the people responding, yes, it is extremely uncommon in "big box stores".

Not in the US, but in Europe it's more common. Shopping malls in Eastern Europe they're not uncommon.

		only those that carry the shopping trolleys up/downstairs, designed so the wheels get locked into place. I have never seen a flat one in anything else but airports or connections between other mass transit transports such as metros and trains. Definitely not in big box stores as they would be inconvenient and slower than pushing the trolley in the flat.
