A nice touch would be an enormous key at the bottom of the escalator in case of emergency. |
|
| |
What if you connected it to the turnstiles? |

Perhaps the effect would be enhanced by painting the front of the train to look like a carved cuckoo.[+] |

I realize you'd smooth the motion, but my brain keeps showing me this vid of a long stream of people on the escalator, glassy eyed, bobbing back and forth to the rhythm of Tick (lean back) (lean forward) Tock (lean back) (lean forward)... priceless. |

Plus you need to remember the Muzak in the background, See Link. |

Its sounds like a great idea: not using power from the grid on escalators. However, I think using subway or other types of trains as a power source is where this idea is half-baked. Many times in the past I've thought about the same wastefulness you've noticed. I always felt that the 'down' escalators should be used to recover energy to put towards the 'up' escalators. This would still not be 100% off the grid, but could help to conserve energy. Besides, the down escalator could be completely gravity fed, as long as it had a governor to regulate descent speed for safety. |

| |
Another problem with the subway train idea is that some subway trains use a flywheel or compressed air energy recovery when stopping to reduce the energy required when accelerating away from a station. |
|
| |
Otherwise I'm quite positive about your idea and its about time escalator companies were more environmentally friendly. |

Most (all?) subway trains are electric - any modern one ought to use regenerative braking and feed the power back to the grid anyway. The brakes should be only for emergency and for parking. |
