The Duronto rakes comprise ICF coaches used in the Rajdhanis and Garib Raths earlier. The Garib Raths had AC III-tier coaches that could accommodate more passengers than usual.

Each Duronto coach is 24 metres long, compared to the regular coach length of 22.3 metres. The distance between coaches is less too - 460 mm instead of the regular 960 mm.

Besides safety and hygiene features like dustbins and fire extinguishers, the trains have sleeker designs for bottle holders and switches, mobile charging points, sliding transparent doors between coaches, and LED night lamps instead of regular fluorescent lights.

The train is built of stainless steel, which is lighter, anti-corrosive and more durable than the conventional 'cotton steel'. An important safety feature is the central buffer couplers whose enhanced load capacity makes the train derailment-proof.
