More fun with passenger information

Paris Line 14 has DMIs accurate to 10seconds. Now thats showing off!

DMIs on the tube are very approximate, as they are operated by often quite long track circuits. Hopefully when lines are ATO'ed, the DMIs will become a lot more accurate, as train location will be provided by shorter track circuits or inductive loop.

Not just on the tube. I was at Newport (South Wales) station recenty, and the three line next train indicators installed by FGW when they managed the station have been altered (presumably by ATW) so that instead of showing the expected time (e.g 23:10) until the train has departed the station they now only show it until the train is expected in more than 5 minues. From 5 minutes to 1 minute this is shown e.g.


This is fine until you notice that it still says four mintues when 23:10 is (by the clock on the display) 3 mintues away. Then after showing 1 minute the display changes to "arrived" - even though the train is still 30 seconds to 1 minute or more away from the paltform - and at stations like Newport you can't even see the train in the distance!
