Abstract
To move a rail-borne vehicle (2) over a preferably ascending partial section, a finite chain section (8) is pulled in a stationary guide (13) in parallel to the rail (23) using a cable (9). The vehicle (2) engages the chain section (8) via a chain hook (19). The two ends (35), (36) of the cable (9) are connected to the leading end (34) of the chain section (8). The vehicles (2) can be moved rapidly with this cost-saving arrangement. It is also possible to overcome steeper uphill sections than in the state of the art (pull-up devices of roller-coasters).
