 Class 73 is a four-car electric multiple unit built by Adtranz. Each four-car train has eight bogies — of which three are powered — with a total power output of 2,646 kW (3,548 hp). The trains have active tilting, which allows speeds 20 to 30 percent higher than conventional trains through curves on conventional lines. Maximum permitted speed is 210 km / h (130 mph). A four-car train is 108.48 meters (355.9 ft) long; an A-series weighs 215.1 tonnes (211.7 long tons; 237.1 short tons) while a B-series unit weighs 216.1 tonnes (212.7 long tons; 238.2 short tons). The trains have a steel body and the entire cabin is pressurized. Rail brakes are installed on all carrying bogies.
