@Mad Doug Biker - just the man!
Have you been watching the Criterium Dauphiné? Is Tournon, where they passed through yesterday, the same Tournon du Rhone that has a vintage railway in it? Is that the Vivarais Railway? I have travelled on the Vivarais, many years ago, and it looks familiar, but the train lines looked double track on the footage from the cycle race.
I have looked at maps and the route of the Criterium on tinternet but I cannot work it out.
I didn't watch, so you probably know more than me, sorry.
Thing is I have never been too much into French railways, so I would need to look it all up. Railway enthusiasm often tends to be somewhat parochial because each country has it's own version of basically the same things as everyone else, so, if you don't experience or know of something foreign, then it isn't necessarily the end of the world. A lot of enthusiasts in this country don't bother with 'foreign muck', with some being downright hostile towards it all, which is quite sad really.
I am always learning things here though - I am into German, Austrian, Polish, Swiss and ltalian trains, but that is because I have visited and experienced their trains in some depth. I was last in France in 1998 unbelievably!
I do read 'Today's Railway Europe' magazine, so I see news, be it from from current operations, from 'light rail' (trams) services or the heritage scene, from France or elsewhere, and it is interesting but one can only follow so much.
I'll go back to France eventually.
