I have edited together the results from a number of visits to the line between Boulogne and Amiens in Northern France during 2012. Trains from Paris to Boulogne changed between diesel traction and electric traction at Amiens. This line turned out to be the host of the last services to have regular diesel loco hauled trains in France, ending during the Winter of 2019/20. As well as the BB 67400 diesels, look out for some familiar traction on aggregate trains.
