Innovations for Deutsche Bahn are a challenge – which Rhomberg Sersa Rail Group accepts.
DB AG has an almost perfect innovation management system in which new ideas are constantly identified, generated and implemented throughout the company. This is also necessary becausse the group has to ensure the maintenance and operation of a network that is over 33,000 kilometres long - while adhering to the strictest safety and quality alert, expertise and experience are required.
Resources that RSRG has at its disposal for one of its largest customers in Germany: “Thanks to our track builders, construction managers and foremen, we have an 4 incredible amount of railway-specific 5 knowledge and experience", explains Norman Krumnow, Head of Innovation and Authorised Representative at Rhomberg Sersa Deutschland. “This enables us to question and optimise products, technologies and processes in a targeted manner.” With success, as shown by a particularly innovative example: the V-TRAS transition module from slab track (Feste Fahrbahn, FF) to ballast roadbed (Schotteroberbau, SchO). “Due to the different stiffnesses, track position errors repeatedly occur between these two types of track superstructure in crossing areas,” explains Krumnow. “These have a negative impact on driving comfort and, unfortunately, travel time.” RSRG has succeeded in producing a linear reduction of the high stiffness from the FF to the SchO, therefore virtually resolving the track settlements.
But this is not enough for RSRG: “We are currently in the process of further developing the product for installation in the crossings between art/engineering and earthworks,” reveals Krumnow. “Our goal is clearly to push ahead with innovations together with Deutsche Bahn and thus generate economic and technical success.”
