\r\nIn the coming weeks the trains will be tested at up to 400km\/h in order to gain certification from the Italian National Agency of Railway Safety for 360km\/h operation on selected sections, a process which requires validation of operation with a 10% safety margin.\r\nThe trains are currently limited to 300km\/h as this is the maximum permitted speed on the Italian high-speed network, although some sections were designed to be upgraded to 350km\/h operation.\r\nThe ETR 1000s are due to begin commercial operation at 350km\/h next year, reducing the Rome - Milan journey time from 2h 55min to 2h 20min.\r\nThe fleet of 50 ETR 1000s is being supplied by a temporary consortium of Hitachi Rail Italy (formerly AnsaldoBreda), which has a 52% stake, and Bombardier (48%) under a \u20ac1.54bn contract awarded by in July 2010. Trenitalia's new flagship train was designed by Bertone and Hitachi Rail Italy is carrying out all project and production phases in association with Bombardier. The trains are being assembled at Hitachi's Pistoia plant.\r\nThe first six trains entered service on the Turin - Milan - Rome - Naples route in June 2015, and so far Trenitalia has received 15 trains. Deliveries will continue at the rate of two sets per month until the end of 2017. The delivery of the ETRs 1000s will enable Trenitalia to redeploy ETR 500 high-speed trains to other routes such as Milan \u2013 Venice and the Adriatic coast.\r\nThanks to its distributed traction, which provides an output of 9.8MW across all eight cars, Frecciarossa 1000 offers much better acceleration than its predecessor the ETR 500. Each 202m-long set seats 457 passengers, including two wheelchair spaces, with four classes of accommodation \u2013 executive, business, premium, and standard.\r\nOperation of the trains outside Italy remains a medium-term objective for Trenitalia with Milan - Paris and Paris - Benelux open-access services considered to be the most likely options. Operation into Germany, Switzerland, or Austria is not currently planned - while the trains have passive provision for 15kV ac traction equipment this would require conversion work.\r\nFrecciarossa 1000 is the first high-speed train to receive EPD environmental certification with CO2 emissions of 28g\/km\/passenger.
