The detailed project report (DPR) of the Raxaul-Kathmandu Cross-border Railway will be ready in a month. On Monday, Deputy Prime Minister and Minister for Physical Infrastructure and Transport Narayan Kaji Shrestha said that India's Konkan Railway Corporation Limited (KRCL), which has been tasked with the preparation of DPR of the railway project connecting Kathmandu with the Indian border town of Raxaul, will submit the report of multi-billion railway project to the government in the next one month. "We have been told that the DPR of the project will be submitted to the government in a month," said Shrestha at a press meet organized at the ministry.

As per the memorandum of understanding (MoU) signed between Nepal and India on 8 October  2021, the DPR of the project should be completed within 18 months, by mid-April, 2023.

KRCL has already submitted the report of the preliminary engineering and traffic survey of the project to the Nepal government. According to the report, the length of the proposed Raxaul-Kathmandu railway will be 136 km. As per the initial report of the Konkan Railway, a total of Rs 320bn will be required to build the broad-gauge Kathmandu-Raxaul Railway. Once completed, the broad-gauge line will give Nepal's capital a direct connection with the Indian railway network, enabling non-stop train travel to all Indian cities. The initial report of the project has shown that there will be 32 tunnels, with the longest one stretching for eight kilometers. The 136-km-long railway project would have 40 km of tunnelway and 35 small and large bridges. The preliminary study has shown that there will be 13 stations on the railway line. After the DPR is received, the discussion about the modality of construction of the project will begin, according to the ministry officials. Nepal has been requesting India to build the project with a grant. The construction of the project will reduce the transportation cost of goods by a massive amount. Once this railway is constructed, goods can be transported directly to Kathmandu from India and third countries.
