Near La Bourboule, a local mineral water bottling plant is currently served by rail twice a day. At 08.40 on June 20th 2005, the double headed morning train of empty wagons arrived at Laqueuille from Clermont-Ferrand, prior to climbing the branch line to the bottling plant.
This traffic by rail was threatened by withdrawal at the end of September 2005, for the motive that the steep gradients limit the loads possible and that the trains are thus uneconomic. But in March 2007, these trains continue to run on Mondays to Fridays. Another mineral water source is to be exploited in the area, and in principle, a new rail branch will be constructed to this new bottling plant soon.
