The current Castrosua bodies (very cutting-edge and even for electric chassis [as is the case with Nelec]) would be nothing without the previous path taken by their predecessors. On this occasion, we would like to recall a body that, in part, changed the perspective of our firm; we are referring to the Castrosua Master 35 body. This model was presented in the 1980s, a very good time for Spanish public transport and an equally good time for our business group, focused on innovating and offering modern bodies. ‘Of all the satisfactions that success brings, few can compare to the possession of a Master,’ we said then in its promotional material. Why? What did Master 35 mean for passenger transport and for our company?
