Double Decker Express are composed of bi-level seating arrangements for passengers with seating capacity of 120 seats, divided into lower deck, upper deck and mezzanine seating area. These days, stainless steel LHB Coaches built at Kapurthala Coach Factory are utilized in AC Double Decker Trains. The Howrah–Dhanbad Double Decker Express was the first of its type to be introduced.

UDAY Express
In 2018, a new generation of Double Decker Express trains were introduced in Indian Railways named as UDAY Express - Utkrisht Double Decker Air Conditioned Yatri Express trains, designed by RDSO. The coaches of these trains have an anti-graffiti vinyl wrapped exterior and have been given a bright color scheme of yellow, orange and pink - somewhat similar to that of the Tejas Express. The train service has been envisioned as a 'luxury' train service for business travelers. According to Indian Railways, Uday Express will cater to the "busiest routes" and increase carrying capacity by 40%. These trains have airline syled seating with a capacity of 120 passengers per coach (50 for upper deck, 48 for lower deck and 22 on the ends) as compared to Shatabdis which can seat up to 78. Also, these coaches are equipped with WiFi infotainment system, have information screens just like Humsafar Express and small dining area in coaches. Uday Express can run maximum 110 km/h and average 62 km/h.
