Since 1958, goods traffic, much of which is shipped onwards by the standard gauge, has been carried by the narrow gauge by a "piggy back" system where the standard gauge wagons (freight cars) are transported on meter-gauge bogie-trucks. In 2004, the Nestlé factory generated over 1500 wagonloads over the system. From December 2006, the TPF handed over its freight traffic to the CFF/SBB/FFS and its two locomotives, numbers 101 and 102, became surplus. In April 2007, they were sold to the MOB.
