Barriers

the biggest issues for this technology is the construction cost will be extremely large with possible low profitability. in the early invention, it may be a bit difficult to impress passengers to use this kind of transportation due to their confidence to this train. however, the inventor has to endure the highly cost if nobody want use it.

A report showed the tunnel would not be economically feasible unless if decision makers included the effects of job creation and the project's ability to revive the construction industry. so that it can attract attention from all parties especially non-government organization(NGO). when NGO interested to know or participate in the project,it would be more easier to upgrade the technology.

one of the experts have advised caution in proceeding with the project due to worries of possible society economic and political hegemony in country. however,it is possible form the logistical advantages the tunnel project would provide.


However the railroad industry has developed various methods and technologies to mitigate the cost impact of the break-of-gauge issue by reducing the need for multiple gauge rail lines.
As well as gauge issues, there would likely be substantial non-technical barriers –including different railway regulators, border controls, and nationalistic trade policies.
