The construction of the Dohazari–Cox's Bazar section of the
Chittagong–Cox's Bazar line was planned to be completed by September 2023.
Bangladesh Railway planned to run at least 4 trains on the line after the construction of the section was completed. But due to various issues the authorities later decided to run an intercity train on the line. In November of the same year, it was announced that the scheduled train on the route would start running from 1 December. Six names were suggested for the train. On 16 November 2023,
Md. Nurul Islam Sujon, the railway minister, announced the name of the train as Cox's Bazar Express. The train went operational from the scheduled date which is 1 December 2023. ==Service==
