HEFES - a fully integrated front-end system for trams and LRVs
posted on 25th Aug 2026 12:25
One module, multiple functions: with the HEFES front-end system, the HÜBNER Group is presenting a new, fully integrated solution for the front end of trams and light rail vehicles (LRVs). The integrated system is ready to install and combines the front-end shell, kinematics, energy absorption and sensor technology all in a single modular plug-and-play solution for the front-end assembly. The module sets new technological benchmarks for safety.
HEFES combines all of the key elements of a front-end system for trams, street cars and LRVs. It has been developed by HEMSCHEIDT Rail, a company of the HÜBNER Group. The system includes the front-end shell and bumper, kinematic elements for precise movement, as well as dampers and absorption elements designed for energy absorption and the reduction of impact forces in the event of a collision. Intelligent sensor technology for monitoring functions is also included in the system.
Christopher Sames, Managing Director of HEMSCHEIDT Rail, explains: “Our HEFES system incorporates HÜBNER’s 30 years of experience that in the field of bumper systems. This is joined with proven expertise in front-end shells, damping and system integration. The decisive factor is not any individual component, but the seamless integration of all the components into a complete, high-performance system solution. This delivers real benefits for our customers in the form of reduced interfaces and lower life cycle costs.”
HEFES is made possible as a complete system through the range of expertise that is available across the HÜBNER Group. The affiliated company HEMSCHEIDT Rail has the overall system responsibility for HEFES, covering the product architecture, the integration of components, the management of interfaces, the supplier coordination and overall system performance. HÜBNER contributes its many years of materials and manufacturing expertise in the front-end field, together with extensive know-how in design and bodywork applications.
Added value for manufacturers and operators
HEFES is the solution of choice for vehicle manufacturers and public transport operators looking for an integrated system solution for front-ends in trams, streetcars and LRVs. Customers benefit from high system availability and low life cycle costs resulting from a fully coordinated set of components.
As a fully integrated front end system, HEFES is simple to install. The modular plug-and-play design with clearly defined interfaces makes it suitable not only for new vehicles, but also for the retrofitting and modernization of existing fleets. In addition, the HÜBNER Group provides comprehensive service support throughout the entire product life cycle - from initial installation through all aspects of system maintenance.Meeting highest requirements for robustness, weight and fire protection
HEFES can be manufactured from glass fiber-reinforced plastic (GRP) as well as polyurethane (PU). The materials meet demanding requirements for robustness, weight and fire protection in accordance with EN 45545-2 R17 HL3. For impact absorption in the event of a collision, HEFES can be equipped with both reversible energy absorption elements such as dampers as well as irreversible elements. GRP offers particular advantages as a material: it is lightweight, corrosion resistant and highly resilient. GRP combines the advantages of glass fibers and plastic to offer an excellent solution for the mobility sector.
