why are the new Victoria and trains so slow?

I understand one of the prerequisites for the introduction of regenerative braking on the Central Line was a requirement to replace older motors in escalators at stations. 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 train out of the station quicker! B2003 |

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 B2003 |

Colin Rosenstiel I did occasionally use Essex Road Station in those days. I didn't pay attention to esoteric details such as lights dimming but I do remember vividly that the entire line seemed dingy and run down and that all the stations had poor lighting. The line was definitely the poor relation of the London Underground family. -- Robin9 In the late fifties I recall, as you say, lighting was poor and the tiling was pretty grim as well. Then, Essex Road platforms had diamond-shaped roundels and included Canonbury in the wording. |
