Connect and Protect – Galea Front end design is caught in a crossfire of influences: safety aspects, economic and environmentally friendly operation, efficient maintenance and repair works. Using innovative GFRP technology, Voith Turbo Scharfenberg combines structural elements and energy absorbing components to form a complete, modular vehicle head, teaming longstanding experience with state-of-the-art technologies. Safe, flexible, lightweight and modular: The Galea concept represents a standardised “framework” for all types of exteriour designs. A perfect combination of individual appearance and optimum energy absorption. Safe Safety plays a major role in rail traffic, with ever increasing importance. To meet these high demands, the Galea inte- grates a multiple-stage crash concept. It was designed to cover the main aspects of the EN 15227 standard, when integrated into a trainset. Crashworthiness and fire protection, as well as noise protection and thermal insulation were taken into account. What stands out: Even the crash elements are made from GFRP. The Galea was developed for Intercity trains up to 200 km / h. 34 Modular Just like every other Scharfenberg product, the Galea has been designed in a modular way. The entire vehicle head is characterised by short mounting times, and – when damaged – can be easily replaced. The same applies to the individual energy absorbing components. This way, train down times are minimised. The entire vehicle head will be delivered ready for installation. Apart from pre-installed pneumatic and electric components, it contains the interior panelling and driver’s desk (according to European drivers desk specifications). Lightweight The heavy-weight steel constructions in operation to date were replaced by lightweight structures using fibre composite materials. The weight reduction results in a higher economic efficiency and environmental acceptability. The load on every wheel is minimised, thus reducing the wear of train and tracks or respectively allowing an increased passenger volume. GFRP Energy Absorber Galea Vehicle Head Lightweight Design Using Fibre Composite Materials Additional Benefit The modular design allows the individual components of the energy absorption concept to be used as stand-alone solutions. This way, the new GFRP technology is open for other applications. Flexible The base of the Galea concept is its internal crash structure. This structure can be adapted to different vehicle heights and widths, but the design and the components making it up remain the same. For the external shell covering this crash structure any design can be realised. The result: individual design paired with optimum safety. Flexibly Adaptable Crash Structure 35

These are also provided with an efficient anti-climbing feature. Energy absorbing components within the floor structure are complemented by crash components at the front side of the A-pillars (EN 15227 crash scenario 3). The GFRP shell of the Galea has been designed such that – should a crash occur – all window panes are securely supported, protecting the driver. The combination of coupler, additional energy absorbing components and A-pillars together with a subtle choice of materials make sure that in case of a crash the driver’s survival space will be safeguarded. Points of reference • Fuel savings of 4848 litres diesel / year* • CO 2 emission reduced by 12 800 kg / year* * based on the following reference vehicle: three-car trainset (DMU / EMU); total weight: 180 t; energy absorbing components between the cars; kilometric performance: 200 000 km / year; weight reduction: approx. 1 000 kg per vehicle head. 37
