Abstract:
1. A seal and connection device between a first train compartment and a second train compartment, comprising a groove bottom and two groove walls, wherein the two groove walls (i) are each perpendicular to the groove bottom, (ii) are separated by a width being substantially equal to that of a slit between the two train compartments, (iii) are each parallel to the transverse ends of the train compartments, and (iv) can each be fixed to separate transverse ends of the two train compartments, wherein the groove bottom extends longitudinally and forms a brim at each of the two ends of the groove bottom so that one brim can abut tightly against a lateral side wall of the first train compartment, and another brim can abut tightly against a lateral side wall of the second train compartment, wherein the slit between the two train compartments is narrowed at a first side of the train during swerving and the brims shift position inwardly with respect to the lateral side walls of the train compartments at said first side, wherein the slit between the two train compartments is enlarged at a second side of the train during swerving and the brims shift position outwardly with respect to the lateral side walls of the train compartments at said second side, thereby forming a smooth hermetic connection between the two neighboring train compartments.
