A high-speed train at St. Pancras International Station in London on October 19, 2010. Plans for a high-speed train between Dallas and Fort Worth were discussed at a public meeting on Monday.

Absent state and federal funding, the future of the high-speed rail project is uncertain, to be kind. This means that in Texas, the bullet train, first unveiled in 2015, is still on the drawing board.

The issues have hampered other high-speed rail links, such as the HS2 project linking London to Birmingham in the U.K., which has seen costs spiral due to revisions and delays in construction.
