An arrangement consisting of coupling elements allowing both pitch and yaw pivotal motion between two coupled modules or coaches, is disclosed. A transverse rod located at the end portion of one module is rigidly secured to a pair of arms and is supported thereby. These arms are rigidly connected to a king-post located in a casing. The king-post is adapted to pivot about its vertical axis. The end portion of the other module is provided with a pair of longitudinally-oriented shafts, each having an outer end provided with a pair of jaw members. The latter can open and close to effect coupling of the modules and are adapted to pivotally grip jaw-receiving portions on the transverse rod.
