Found this on YouTube yesterday... Not quite a TGV, but gotta hand it to him for trying!!
Now I aint been on a train for years, but thats fkin mad!! I never remember a train accelerating for that long haha! I guess he was running late. Any further and he'd have been going back in time!!
It's on the stretch from Moreton to Meols btw, quite a long stretch of uniterputed line, probably the only place he could have done it safely lol.
