After World War Two the site was restored and another carriage from the same manufacturer was turned into a replica of Foch's carriage. It's this that you can still see today. Outside the small but interesting museum, there are a number of memorials related to both World Wars and the location of the tracks and carriages is marked out in stone.
One of the more modern memorials - this one to peace.
The site is level with fine gravel paths - it's quite a wheel from the car park but completely flat and thankfully shaded - this was the day it hit 40 degrees in Paris! The museum itself is accessed by several steps and there is a small, elderly but serviceable platform lift. I had to get No-so-small Scottish Boy to fetch someone with the key (his first French lesson turned out to be "l'acenseur s'il vous plait"). There's another platform lift inside, which is worth using to get up to the rest of the exhibit.
There seems to be big plans to update the museum - and hopefully also both the access and the website, which is a gem of a site, complete with Forrest Gump soundtrack and a Wanadoo e-mail address, that will take you right back to the late 90s!
