Conspicuously missing from TFA: any measurement of the escalator's width.

There's no shortage of single-file escalators in NYC. I wildly surmise they're seen as fancier than the two-person-wide kind associated with subway stations and malls.

The Marriott Marquis in Times Square has two single-file escalators side by side — presumably the height of decadent luxury. Video: https://youtu.be/35-2FAI2DKU

Even for the subway there are single-file escalators, like the one going down to 34th St Herald Square between 32nd and 33rd St.

Without measurements, I can easily think of two other contenders:

- The Google employee escalator at Pier 57.

- The escalator to leave Delancey-Essex station.

Japan has been pushing for people to stand on both sides of the escalator. My dad thought it was due to unbalanced wear. I assumed single-file escalators were more efficient given that most people stand, they want to discourage walking, and it gets rid of the unbalanced load problem.

Faster indeed

Are the narrow escalators retrofits? IE, were there originally stairs that were converted to escalators?

Port Authority is full of them — every single platform, I think.

I don’t know if that’s sarcasm or not, but that’s the norm for shops in the uk (where shops are large enough to warrant escalators)
