U.S. border authorities have temporarily halted Union Pacific train traffic to Mexico via the Eagle Pass gateway in Texas due to the <a href="https://www.foxbusiness.com/category/fox-news-illegal-immigrants">growing migrant crisis</a>, the railroad said.

The work stoppage will halt movement of thousands of tons of customer freight.

In a statement to FOX Business on Thursday the rail operator said it is still preparing for operations to resume.

"While there is not yet an estimated time on when U.S. Customs and Border Protection will reopen the Eagle Pass gateway, we remain in close communication with multiple government agencies and our customers. Thousands of rail cars cross the border at Eagle Pass each day and once the gateway reopens, our goal is to quickly get trains launched and restore cross-border movement. Those trains already enroute (sic) are being staged, while any under embargo are being held at origin to alleviate congestion near the border."

The pass is one of the busiest gateways between the <a href="https://www.foxbusiness.com/category/fox-news-mexico">U.S. and Mexico</a> and was closed on increasing reports of migrants from Mexico riding on rail wagons to cross into the small Texas city.

The rise of migrants prompted Eagle Pass Mayor Rolando Salinas to issue an emergency declaration, citing "severe undocumented immigrant surge".

The situation is expected to continue for seven days from Sept. 19, according to the city's official account on <a href="https://www.foxbusiness.com/category/social-media">social media</a> platform X, formerly Twitter.
