I read that it is a terminus so that means there could be stairs??>

Well terminus I think technically means a dead-end train station - terminal - end of the line but in reviewing info and jamikins recollection it seems Dijon-Ville station is not a terminus but a go thru station where trains stop for a few minutes and keep heading out - those type of stations necessarily have to have passageways to get to the other platforms - many now have elevators - in big stations like this - for the physically challenged but not all.

We will certainly take the direct train if there is one.Knees are good now but stairs can aggravate the situation. Travel is tough on older bodies!
