They share their supply with the traction and needed to be able to handle the greater variations in supply voltage. Does that mean the escalators speed up slightly when a train brakes into a station?  Seems a good idea - get the passengers from the last trainout of the station quicker! Hopefully they stay the same speed, but don't draw as much "external" power for a few seconds. Ah pity. I had images of a couple of particularly full trains pulling into a station at the same time and people being flung off the top of the escalator over the ticket barriers Did anyone else here ever stand on the platform at Essex Road in Northern City Line days? The platform lights were fed from the traction supply so dimmed sharply when a train started away. Of course the platform was empty at that point as the passengers had all got on the departing train but we were changing directions there on the Underground trip in 1970. -- Colin Rosenstiel |

I can see the raw text that reached my newsfeed and what I quoted is all there is. It seems to be something about Robin's news arrangements because I've seen the effect before and only with his postings. -- Colin Rosenstiel |

Maybe it's some sort of interaction problem between his outgoing newsfeed and your incoming newsfeed. My news server (Virgin Media) has received his complete post, as has LondonBanter.co.uk and Google Groups. -- Richard J. (to email me, swap 'uk' and 'yon' in address) |
