5 Figure 3: EUDD performance and acceptance tests in a simulator ( Siemens) Compared with EUDD, the EUCAB working area not only covers the driver's desk but also the specification and development of whole driver's cab, including HVAC (heating, ventilation, air conditioning), cab equipment, interior design and lighting, crash structure for driver protection, and the frontend shell. The overall objectives remain: cost reduction along the entire life cycle chain, improved ergonomics and driver protection. EUCAB working process As the other sub projects and working areas within MODTRAIN, EUCAB applies an incremental process illustrated in figure 4. Based on existing international standards (EN's) and mandatory TSI's, industry and operators commonly develop in a stepbystep and interactive, integrated approach: The train architecture with FBS (Functional Breakdown Structure) and PBS (Product Breakdown Structure) Functional requirements specifications (FRS) System requirements specifications (SyRS) Operational requirements specifications (ORS) Functional interface specifications (FIS) Standards for selected components For EUCAB, the specs development process has been supported by detailed analysis of the driver's working place of modern reference rolling stock (Germany, Austria, France). These investigations were mainly performed by IAS Berlin with support from UPC Barcelona. By applying thoroughly defined intermediate milestones for the specs mentioned above ("intermediate design freeze"), two stages of hardware mockup's in 1:1 scale are planned within the EUCAB workplan:

7 o Reduced number of HW elements by shifting HW functions to SW functions => displays allow for better accessibility for the driver and they are more flexible o Enhanced functional modularization improves userfriendliness and enable the driver for quick learning and further training o Harmonization of the important operations (e.g. driving/braking with integrated master controller) o Design optimized for larger series (min. 15% cut of LCC calculated in EUDD project). Cab interior and design, including interior lighting, cupboards, fire fighting equipment, escapeoptimized door between cab and passenger compartment Dummy for the HVAC Frontend shell, aerodynamically optimized Crash structure for driver protection according to TSI scenario 3 "truck on level crossing" (figure 6) With the MODLINK mid term conference on 14 February 2006 at the German Museum for Technology in Berlin the EUCAB industrial design mock has been presented to the MODTRAIN project partners and interested journalists. High level speakers (e.g. Hartmut Mehdorn, CEO of Deutsche Bahn) provided the motivation to project partners to proceed with the results already achieved. Figures 7 and 8 should provide impressions about the "close to reality" nature of the EUCAB industrial mockup.
