SNCF BB 67442 is hauling train 3837 Nantes Toulouse. 
Due to a new low speed limit for many kilometers long, it is approaching the river Lay at only 60km/h, and then 40km/h on the bridge over the river. The central part of line Nantes Bordeaux is in rather bad shape, with a blurry future.
Nonetheless, the ten coaches of the train are highly occupied. It is the evidence that this line is a very useful link between the main cities of the atlantic seaside of France - Nantes, La Roche sur Yon, Luçon, La Rochelle, Saintes, Jonzac, Bordeaux.
Is it a dream to think here of a modern diesel hauling on a modern infrastructure?
