I saw this feature:
about the Rhaetian Railway the other day on the BBC website then realized there might be a video.
'Rhaetia' - also spelled 'Raetia was a province of the Roman empire which is now part of Switzerland. The map on this Wiki will show you where: Rhaetia
I've always found it interesting because languages fascinate me and, while it's spoken by very few people, it is still one of the four official languages of Switzerland. You can learn more about it here: Romansh/Romansch
From the Wiki
Romansh is a descendant of the spoken Latin language of the Roman Empire, which replaced the Celtic and Raetic languages previously spoken in the area by the 5th century AD
I also love trains, which is why this video is here. Enjoy.
