Throwing this completely off topic. But what do SWT Class 159 systems base their PIS on?

I caught the late night Bristol Temple Meads - Salisbury the other evening (Can't remember the time off hand, but I believe it's 22:25 or 22:20 pretty sure it's the former...)

Well when we left the PIS either hadn't been programmed properly. Or was very confused. The system annouced: "This is Keynsham" well it is was Keynsham. That train doesn't call there so we shot straight through understandably. Eventually we arrived at Bath Spa where the system announced: "This train is for Bristol Temple Meads Only" A few passengers looked nervous as we'd just come from Bristol Temple Meads.

Eventually we called at Bradford-on-Avon. Well the PIS thought it was Bath Spa. The same happened at Trowbridge which the PIS thought was Bradford-on-Avon. I got off at TRO so no idea what happened or if it sorted itself out. But for a non regular passenger, that would certainly confuse me slightly!

With SWT PIS I've also known it to get stuck in a loop. So it announced the station calls as it would do normally. Then started again a few seconds after completing the "round" This went on for ten minutes before the Guard looking rather flustered ran into the back cab to switch the thing off!

Thanks for posting, thetrout.  ;)

I've simply split your post off and started a new topic with it here, as it seems to merit a discussion of its own.

Hope this is alright, CfN.  :D

Sounds like this system was taking the PIS.

Works on GPS, so if it is still set up for the last journey it will announce everything backwards. Announcing that the next stop is x when you are leaving x.

With refence to BNM's comment....

Well it would wouldn't it ? Especially if the train was going to ...wait for it ,wait for it ... Water...loo..... ::)

Quite correct: needs to be set up by the guard, occasionally they'll forget, or there may be a fault that means for some reason it can't be done.

In that event the system will simply make the announcements it would have done in a given place on the outward journey; in my experience when that happens it will announce "we will shortly be arriving at..." just *after* leaving the station in question, and the announcement giving the destination will be similarly confused.
