At that time, the railway authorities made several promises, including building environment-friendly infrastructure and constructing overpasses and underpasses to facilitate elephant movement. However, they have not fully fulfilled these promises. Moreover, the infrastructure has been built at a huge cost, yet it is not entirely suitable for use. The underpass created for elephant movement is too narrow, so elephant herds cannot use it.

In 2010, the Executive Committee of the National Economic Council (ECNEC) approved the construction of a railway line from Dohazari in Chattogram, passing through Ramu to Cox's Bazar and from Ramu to the Myanmar border at Ghumdhum. The project's construction cost, including the Ramu-Ghumdhum section, was estimated at BDT 180.34 billion. Later, the construction of the Ramu-Ghumdhum section was suspended, and Bangladesh Railway initiated efforts to reduce the total cost to BDT 127.13 billion. A significant portion of this budget has been spent building various infrastructures within the wildlife sanctuary.

According to Forest Department sources, in 2012, during the initial feasibility assessment, the Forest Department opposed the construction of the railway line through the protected forests of Chunti, Fasiakhali, and Medakachhapia. However, after receiving assurances for maximum wildlife protection and ensuring their normal movement, the Forest Department granted permission for land use. Later, according to agreements and notifications made with the two agencies, the Forest Department repeatedly urged the railway project division to comply with their demands. However, the railway's project division did not pay heed. Most recently, on October 13, an elephant was killed by a train.

Train services on the Dohazari-Cox's Bazar railway line began in December last year. Currently, three pairs of trains are operating daily. When fully operational, nearly 23 pairs of trains will be running, further increasing the risk to elephants and other wildlife.

Professor Dr. Monirul Hasan Khan of the Department of Zoology at Jahangirnagar University spoke to Bonik Barta regarding the construction of the railway line and infrastructure through the protected forest areas, saying, "Heavy transportation infrastructure like a railway should never have been built in a wildlife sanctuary. Even before the project was completed, an elephant was killed by a train. In the future, train traffic on this railway will increase. The project authorities have no idea about the level of risk that will be created then."

On October 17, the Wildlife Management and Nature Conservation Department sent a letter to the project director of the railway. The letter said, "According to the government notification issued on May 23, 2019, the railway must construct international-standard overpasses and underpasses for the safe movement of wildlife in the project area. Although two underpasses have been built, they are not wide enough for elephant movement. As a result, elephants cannot use the underpasses."

The letter further stated that although there were plans to build two overpasses, only one has been constructed. According to condition 4 of the notification, sound barriers were to be built in the protected forest areas; however, this has not been done. As a result, noise pollution is disrupting the normal habitat of wildlife. Additionally, the issue of controlling the speed limit of trains in the sanctuary is not being followed.
