RhB sound measuring car Xak 9371. This is one of two cars that belong together, they are currently being completed. On their yellow ends they have the RhB/MGB central buffer and double screw couplers, on their orange ends they have the SBB-Brünig/LSE/BOB automatic GF couplers, so they can be operated on these most important narrow gauge networks of Switzerland.
