| A 10 to 20% increase in car body width allows for the accommodation of another seat per row in passenger stock. This has strong effects on both energy efficiency and life cycle costs.

Focusing on rolling stock only, wide-body stock is the most promising design option as far as space utilisation is concerned. Realisations and design studies of wide-body trains show strong seat-specific advantages with respect to energy efficiency as well as both investment and operation costs. The main barrier is clearly the incompatibility with many infrastructures. Even though wide-body design violates the existing UIC gauge and thus impedes interoperability of high-speed stock, wide-body trains can often be accommodated on parts of a network. This holds especially for regional and local operation where the potential for wide-body trains is high. |
