I noticed that the escalators on the tube have a brush running the full length on both sides of the escalator. If this was fed with neutral coloured shoe polish, people could buff their shoes on it on the way to work by holding the toe of the shoe against the brush as they were moved past it.
There
may need to be a rail or something to stop the toe getting caught against the side of the escalator and th leg being twisted and/or dislocated but these minor details can be worked out in testing.

An escalator, but not at all funny. [8th of 7, Jun 10 2015]

Schindler, who are one of the leading manufacturers
of escalators (and, amusingly, of lifts) estimate that
the habit of buffing ones shoes on the side-brushes
costs the escalator industry between 70 and 100
million US dollars per year worldwide, due to
accelerated wear and the need to replace worn
brushes. They also claim that 30-40% of escalator
accidents are caused by this activity. |
|
| |
In 1993 in Japan, there was one of the worst
escalator accidents on record, when a brush broke
and the free end caught between two of the treads.
This created a loop which, as the escalator ascended,
peeled off the entire brush strip creating a loop
which travelled upwards (at twice the escalator
speed, thanks to the geometry of the situation),
sweeping the tightly-packed commuters off their
feet. |

If people are doing it anyway, that shows it should be built in as a feature to avoid the wear and accidents you refer to. |
|
| |
That accident does create the image of a kind of inverted linear mexican wave with everyone being sequentially hurled to the ground |

They just got brushed off, shirley ? |

Is there a video ? We would pay a dollar to watch it. |

Errr, right. What are you up to, now the 787 programme is winding
down ? |
|
| |
//They just got brushed off, shirley ?// There were
some awful injuries. I suspect that the authorities
swept it under the carpet. |
|
| |
We need a Tube here. Oh wait... |
|
| |
// I suspect that the authorities swept it under the carpet. // |
|

Presumably that makes you bristle with indignation ? |

It's as well to get a handle on these things early, so you know how it's going to pan out if there's a dust-up. |
