STB Approves Laredo Gateway Industrial Railway 2.6-Mile Spur

WEBB COUNTY, Texas – The U.S. Surface Transportation Board (STB) on 16 June 2026 issued a decision authorising Laredo Gateway Industrial Railway LLC (LGIR) to build and operate a 2.6‑mile rail spur that will link Union Pacific Railroad’s Laredo subdivision mainline to the Gateway Industrial Park north of Laredo. The line, developed by LGIR’s parent company Kraus Development, is designed to serve shippers using the Laredo Port of Entry for cross‑border freight. Ironhorse Resources Inc. (IHR) will operate the line under a separate agreement, subject to future STB approval.

What Is the Full Scope of This Project?

The 2.6‑mile rail spur will extend from an existing Union Pacific mainline into the Gateway Industrial Park, situated near the intersection of Interstate Highway 35 and State Highway 255 north of Laredo. The park is a greenfield development by Kraus Development aimed at warehousing, logistics, and light manufacturing tenants, all of which will gain direct rail access to the busiest US–Mexico freight gateway. LGIR has not disclosed construction timelines or total capital expenditure, but the railroad confirmed it has engaged short‑line specialist Ironhorse Resources to operate the line upon completion. IHR must obtain separate STB authority before commencing operations.

Key Project Data

How Does This Compare to Similar Projects?

The 2.6‑mile spur is a modest addition compared with other border‑area rail investments. In 2024, CPKC completed a second span of the Laredo International Railway Bridge at a cost of $100 million, doubling the crossing’s capacity to 80 trains per day (Source: CPKC, 2024). Union Pacific itself has injected more than $80 million into yard expansions around Laredo since 2023. Even short‑line spurs in neighbouring border states have recently been larger: a 12‑mile industrial lead approved in Pharr, Texas, in 2025 served a 1,200‑acre logistics park, while the LGIR line targets a single development site. Cost benchmarks for simple spur construction in the region typically range from $2 million to $5 million per mile, but the STB decision carried no financial disclosures, so any estimate for this project remains speculative. U.S. rail carload and intermodal volumes recorded year‑on‑year gains in the week ending 13 June 2026, underscoring the sustained pressure to add capacity at the Laredo gateway (Source: AAR, 2026).

Editor’s Analysis

The STB’s rapid treatment of a 2.6‑mile spur – at the same time it is managing the high‑profile Union Pacific–Norfolk Southern merger review – signals a policy focus on clearing small‑scale border projects that can quickly turn asphalt into freight lanes. Laredo already handles over 30% of U.S.–Mexico rail trade, and 2025 logistics data shows shippers shifting supply‑chain gravity from China toward Mexico and Southeast Asia (Source: FleetOwner, 2026). If this spur triggers similar park‑and‑spur developments along the I‑35 corridor, it could further entrench Laredo’s role as the hemisphere’s primary nearshoring rail hub, while boosting Union Pacific’s cross‑border franchise without requiring the railroad to deploy its own capital.

FAQ

Q: What is the Laredo Gateway Industrial Railway and why was STB approval needed?
A: It is a new short‑line railroad created by Kraus Development to build and operate a 2.6‑mile spur into the Gateway Industrial Park. Because the line involves new construction connecting to a Class I railroad, the STB must authorise its construction and operation under U.S. law.

Q: Who will actually run trains on the new line?
A: Ironhorse Resources Inc. has an agreement to operate the line, but it must first obtain a separate operating authority from the STB, which has not yet been granted.

Q: When will the rail line be completed and open for service?
A: No completion date has been announced. The STB decision only permits construction to begin; timelines will depend on Kraus Development’s park construction schedule and any remaining regulatory steps for the operator.
