These trains have a top speed of 300 km/h, have 25% more seats and consume 40% less power. They comprise of two short wheel base power cars and nine articulated trailer cars. Due to the North East Corridor track condition as of now, the Avelias would be limited to 255 km/h speed during the commercial runs.
