A UAE-based company has proposed an ambitious high-speed underwater rail link between Mumbai and Dubai, seeking to reduce journey time to two hours. The National Advisor Bureau Limited intends to build a train capable of reaching speeds of 600–1,000 km/h, providing a novel alternative to air travel. The project, first suggested a few years ago, is still being discussed, with no major progress on approvals or construction.
In addition to passenger transportation, the rail line is planned to improve the transit of goods, particularly crude oil, thereby improving trade links between India and the UAE. A YouTube video claiming to represent the corporation depicts how the futuristic train network may look if completed, including a view of the aquatic world along the way.
The major infrastructure project is expected to cost billions of dollars due to the technical and engineering constraints involved. If permitted, the rail link may be operational by 2030, offering a faster and more environmentally friendly transit option. The effort is being constantly monitored while conversations continue, and its success is dependent on governmental permissions and financial backing.
