Trenitalia ordered 28 new trainsets, which were delivered in mid-2008. In December 2008, the design was used for the first time in the regular service between
Rome and
Bari. From December 2008, Trenitalia introduced new brand names for categorising trains according to their maximum speed. The second fastest train category - after
Frecciarossa (Red Arrow) - is
Frecciargento (Silver Arrow), for trains with maximum speeds between 250 and 285 km/h. With this, the trains operate as "ETR 600 Frecciargento" and "ETR 610 Frecciargento". With the brand names, new color schemes were also introduced, which the FS presented on 13 November 2008. The car bodies developed by Alstom were built by the Alstom plants in
Savigliano near
Turin, and the electrical equipment in
Sesto San Giovanni near
Milan. ==Technical data==
