in 1994, the next generation, the etr 460, styled by giorgetto giugiaro, began service. though plagued by technical teething problems, the etr 460 introduced several innovations, such as more powerful ac asynchronous motors. further, the pistons actuating the anti-tilting action were placed in the bogie instead of on the carbody sides: this permitted the reorganisation of the vestibules and passenger compartment areas, improving comfort. the bogie-to-body connection is extremely simple and easy to make, with clear advantages for maintenance.
