Locomotiva a vapore FS 625.153

Locomotiva a vapore FS 625.153 stands as a preserved steam locomotive monument in the Fiumara area, at Largo Ernesto Jurse. Its broad boiler dominates the dark iron frame. The FS 625 class served mixed passenger and freight traffic on secondary lines across hills and plains. This engine carried both people and goods. Engineers combined superheated steam with Walschaerts valve gear to increase power over older designs. A front bogie helped the locomotive negotiate curves. Railway workers called these engines “signorine” because they showed a gentle rocking movement on straight track. Its rods and springs suggest that motion. Preserved within the Ansaldo works, this unit remains linked to the industrial history of its setting. The tender carries heavy coupling equipment. Restored external fittings reveal the practical details of a working railway machine. Brass fittings contrast with dark iron. The front bogie shows how railway engineering addressed tight curves and rail wear. That compact mechanism gives the locomotive its clearest technical story. Locomotiva a vapore FS 625.153 connects railway design with the former Ansaldo setting.
