Richard, I believe all the Virgin trains have GPSes, they're also like  
faraday cages so you're lucky if you get a good fix from your own GPS  
device (sometimes I have, other times I haven't).

I've now emailed, no idea if they'll come back with anything, I think  
it's a case of this guy goes to the marketing department and they say  
"how much press could we get off this and how much effort would it  
take". As the amount of press is probably minimal I'm not going to get  
my hopes up but I thought I'd ask him anyway.
