Hi all,

Does anyone have any information about this afternoon's 1S51 - 11:03 Birmingham to Glasgow C Virgin Voyager service?

It is simply showing up (or at least was) just displaying "No Report" on the nationalrail website, so I don't know how it's doing.

Any information would be very helpful.
Ian

Yes, I think it's been cancelled personally. I went out to look for it, for a minute or two, but I was deterred by the heavy rain. I would've normally waited for it to come for a while, but because I knew It's probablly not running anyway, I didn't wait around much.

How do 220/221s GPS systems work anyway?

Edit: Does anyone know If any of the first two Voyager services (09:03/11:03 Birmingham to Glasgow) return with the same unit/s on either of the last two services back from Glasgow?

O well.. That's one service which has probablly been cancelled. Doesn't stop me from seeing even more though ;) I'm now going to go & see a 57+390 combo on the 11:53 Carlisle to Euston.

I don't know how they work but I believe they control the destination + stops scrolling screens so as long as the train crew set the right route the screens should be correct. I think it would also send a message to NRE's HQ letting them know wheer the train is for up-to-date info.

Generally GPS systems work by sending radio waves to 3 or more satallites and then works out the time for the reply fom all the available satillites and so can pinpoint the position of the Transmitter/Reciver. They can just work off two sats but the accuracy wont be very great as it will only have a 2D picture of where you are rather than a 3D picture. The more sats available the more info the GPS set gets so the more accurate it will be.

the GPS in a 220/221 is for its onboard diagnostics use... the NR website uses reports from line-side equipment. This is why the Cambrian Line and Heart of Wales have weird time reports because of the long gap between token requests.

So Which unit/s did I miss?

Also, could somebody possibly get hold of gen for tomorrow's S&C 220/221/57+390 diversions, because I'll be away from them till the evening, and just watching them from home when I get back?

Many thanks to anyone who can inform me of what I miss.
