  "textContent": "The vehicle train consists of two or more superstructures connected by joints and supported on a common bogie via two secondary spring pairings. Each vehicle unit has devices for statically determined three-point bearing, using valve-controlled connection lines (6). The number of lines is chosen so that the number of independently regulated secondary springs (4-4''') and level regulating valves (5), corresponds to the sum of the degrees of freedom for dipping, galoping, and rocking motions of the vehicle train. Arrangement of the valves permits a defined statically determined support.",
