Euro Tunnel trains no chance, not even I can get access for that type of shot and I work there, as they only run round a circuit on the terminals. Euro Star trains will be just as hard as the high speed line has a fence along it's length to keep people off the line though there maybe places where you could get next to the fence and be able to focus through the fence.
Yep I have found such a place near Smeeth.
Smeeth, Ashford, Kent, UK and 51.107484, 0.955922 (search these coords in Google maps) it looks like you can get to this area.
I will have to do a rekki. I suppose I will have to take my jump leads and snips to get a decent shot.
