Before each season, which begins this year on June 20, the cars on the Furka Mountain Steam Railway (Dampfbahn Furka Bergstrecke) have to prove that their brakes are working perfectly. For this purpose, brake tests are carried out on each individual carriage and documented. Here it is the turn of the two-axle covered freight car X # 2925, which is being pushed by the steam locomotive HG 4/4 # 704 on the adhesion section passing the Realp entrance signal.
