Since February 2003, within the framework of a large-scale contact wire renewal programme, DB Bahnbau GmbH, a subsidiary of DB Netz AG, has been using the new Plasser & Theurer FUM 100.128 catenary renewal machine on German Rail (DB AG). Using this new machine and its ancillary vehicles, the contact wire and carrying cable can be installed, in a single working pass, with the final operating tension and in the correct stagger. Thus, compared to using conventional technology, a 50% reduction in track possessions and, moreover, a reduction in costs can be achieved.
