I took this photo of the Loire this morning in the early train from Blois to Nantes. The windows were very dirty!.
J’ai pris cette photo de la Loire de bonne heure ce matin dans le train de Blois à Nantes. Les vitres étaient très sales.
The Loire Valley and especially Blois
We see the same here on commuter trains sometimes- the windows are due for a washdown.
I don’t think they ever wash them here!
