Posted by Wado MP73 on Mon Feb 8 23:31:51 2010, in response to Re: Video showing Paris Metro Line 1 headway, posted by Easy on Mon Feb 8 22:00:22 2010. Line 10 and 11's interval never go under 120 seconds so I don't know where the "all of the other lines" comes from. Line 14 now does 90 seconds (not when I rode it yet), but it's ZPTO and designed so from the beginning.Anyway, the official figure is 105 seconds for line 1. I went through enough pdfs on RATP's site. No mention of recent changes and certainly not 90 seconds in 2007 when the video was posted. A study from Oct. 2008 about the automation says "currently 1m45s". IIRC, the terminal configuration and driver-started ATO relay will only allow 100 seconds at best and that's for delay recovery. Driverless automation of the line has been delayed to 2012, BTW. It could have been after a delay in service and since this is at the last stop of the line before the relay, where there are no departure timer, it's not impossible to temporarily have a shorter headway. But all departing trains at all stations will be held if arriving too early by the departure timer. Mind you, we are talking about ten to fifteen seconds in difference. It is easy to speed up the video without looking unnatural too. I tend to trust current RATP's documents than posts made on Skyscrapercity too. And even at 105 seconds, I'd say it's impressive. |
