Modifications
Although it is cosmetically identical to its sister machine, the ED73 features several improvements over the ED72.Amongst these are: bogies with pneumatic suspension; anti-skid devices; outward opening pneumatic doors (only one unit from the ED72 series had these installed); pneumatic doors between carriages; new transmission permitting a top speed of 120 km/h (≈ 75 mph); and eight traction engines with a combined maximum power output of 1,560 kW — allowing for an acceleration rate of 0.41 m/s² when the train is fully loaded.
The final modification was made inside the first class carriage, where a special compartment and toilet had been built for disabled passengers. Ironically, the carriage isn't designed to enable easy access for passengers in wheelchairs.
