The Böblingen maintenance hall and depot of Schönbuchbahn, which Furrer+Frey equipped as part of a complete contract, has recently been successfully commissioned. The complete system comprises five tracks with fixed and one with a moveable Conductor Bar as well an interlocking system with Automatic Connection to the Return Conductor (ACRC) protecting the interfaces to the washing plant, the underfloor lifting system and a crane. Furthermore, the accesses to the roof platforms and the fall protection flaps are monitored by the ACRC system.
