Most of its users concentrate between Lleida and Balaguer, where a frequent service is offered, with few trains continuing to La Pobla de Segur.

Since 2009, a heritage railway service branded Tren dels Llacs (English: "Lakes Train"), in reference to the number of reservoirs skirted by the line north of Balaguer, has been running on the railway.

Between 1949 and 1951, it was extended to the current northern terminus in La Pobla de Segur.

The line was targeted for closure by the Spanish government in the 1980s, with great opposition from regional and local administrations.
