Like most light railways, the line from Noyelles to Dompierre meandered through the countryside, taking advantage of the contours to avoid earthworks, but at the cost of a slow journey. Going up took just over the hour and coming down, somewhat longer.

The introduction of autorails (railcars) in 1936 in the form of a number (10?) De Dion Bouton NJ models, some of which survived until around 1960, probably reduced running costs but seem to have done little to improve the timetable.
