[3] The line was electrified on 27 August 1984 at 25 kW 50 Hz, and was equipped with the restrained permissivity automatic blocking system, which since the 1990s has offered increasingly unsatisfactory operating conditions with respect to the increasing mixed passenger and goods traffic on the line.

It runs in generally southwestern direction, passing through Poix-de-Picardie, Abancourt and Serqueux until it reaches its terminus in Rouen.

In 1992–93, this line saw transport of 8,000 tonnes of goods daily, 60% of it in the Amiens - Rouen direction.

On the other hand, passenger demand is not strong but tends to be focussed by the express TER Rouen - Amiens - Arras - Douai - Lille axis.

The typical daily service (2019) sees five passenger trains in each direction, two of which are extended to/from Lille.
