Double Decker Express are a series of trains started by Indian Railways for shorter routes in order to serve more people than a traditional chair car carriage.

In 2011, new fully-AC Stainless Steel LHB Double Decker were introduced in India.

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.

According to Indian Railways, Uday Express will cater to the "busiest routes" and increase carrying capacity by 40%.

The second service was launched on 26 September 2019 between Visakhapatnam and Vijayawada with 7 stops en route, and was later extended till Guntur.
