STB Signs Off on New Maverick County, Tex., Line

Why It Matters

The approval creates a dedicated cross‑border corridor that could ease congestion, improve safety, and boost competition among freight routes, strengthening U.S.–Mexico trade logistics.

Key Takeaways

• STB approved GER's Southern Rail Alternative for Maverick County line
• Line will connect Eagle Pass border to UP's Eagle Pass Subdivision
• Project requires agreements with UP and BNSF before construction begins
• Expected benefits include safety, reduced grade crossing delays, and better air quality
• GER must file status reports semi‑annually, then annually; deadline May 12, 2026

Pulse Analysis

The United States‑Mexico border is a critical freight corridor, handling billions of dollars in annual trade. Yet congestion and safety concerns at traditional crossing points have prompted industry players to seek alternative routes that can separate rail and commercial motor vehicle traffic from dense urban cores. In this environment, the Surface Transportation Board (STB) acts as the federal arbiter for rail line exemptions, evaluating proposals for their economic viability, environmental impact, and alignment with national transportation policy. Its recent approval of a new line in Maverick County reflects a broader push to modernize cross‑border logistics.

The approved project, submitted by GER—a subsidiary of Puerto Verde Holdings—will extend from the Eagle Pass border southward to connect with Union Pacific’s Eagle Pass Subdivision, creating a dedicated rail and CMV corridor that bypasses the city’s downtown area. The STB designated the Southern Rail Alternative as the environmentally preferred route, subject to mitigation measures such as fencing, monitoring and patrols. Crucially, GER has pledged not to commence construction until it secures traffic‑shift agreements with both Union Pacific and BNSF, ensuring that existing carriers retain access and that shippers avoid service disruptions.

If built, the line promises measurable gains: reduced grade‑crossing delays, lower emissions, and enhanced safety for both freight trains and road vehicles. By offering a competitive alternative to the existing Eagle Pass bridge, the corridor could attract new freight flows, stimulate economic activity in Maverick County, and deepen the binational trade network that underpins the U.S. manufacturing supply chain. GER must now report progress to the STB within six months and annually thereafter, while stakeholders watch for the May 12, 2026 deadline to challenge the decision, a timeline that will shape the project’s ultimate trajectory.
