Mission Rail Park — An integrated industrial infrastructure platform

Why Mission Rail Park

Six things no other site in the corridor can offer together.

Rail parks offer track. Utility districts offer power. Mission Rail Park is the only site in a survey of 34 industrial parks across Greater San Antonio–Austin that puts dual Class I rail, interstate access, prime generation, thermal energy and guaranteed water on the same 1,000 acres — under one operator, ready for a manufacturer to build.

01 · RailExisting

2 × Class I

Union Pacific and BNSF both connected into the park — unit‑train capable, with on‑site switching, transload and car storage by Gravity Rail.

65,000 LF of track · 800+ railcar storage spots · 150‑car unit trains

05 · SteamFunded · 2028

Steam >85%

Waste‑heat recovery from turbine exhaust turns 1,000 °F heat into process steam, delivered by insulated pipe to each facility.

06 · WaterExisting

600M gal/yr

On‑site well water — 1,840 acre‑feet a year guaranteed by water rights exclusive to park tenants — plus wastewater treatment and reuse on campus.

Two products · one platform

The land and rail platform is open today. The utility overlay is funded and in build.

Prospects care about a different half depending on where they are in the decision. Both are designed to be contracted together: buy or lease the parcel, then sign a 20‑year service agreement for power, steam, chilled water, water and wastewater.

The utility overlay

A combined heat & power plant inside the park: gas turbines produce electricity, their exhaust makes steam, the steam drives absorption chillers. Every service is metered and piped to the tenant under a 20‑year agreement with guaranteed min/max hourly volumes.

Rail

Two of the largest railroads in North America. One park.

Only six Class I carriers serve the United States. Mission Rail Park has both Union Pacific and BNSF connected on site — which means competitive rail pricing, North‑America‑wide reach to source raw materials and distribute finished goods, and unit trains received and departed with switching and transload handled by the park's operator.

01
Dual Class I interchange
UP + BNSF, co‑located with the Union Pacific railyard. Cross‑border reach to Mexico and Canada.
02
Unit‑train capable today
Two 8,000 ft unit‑train tracks; extra‑large trains up to 150 cars; multiple unit trains per day plus manifest service.
03
Engineered for expansion
20,000 ft loop and seven 4,000 ft storage tracks engineered, all with access to both carriers — built to tenant need.
04
Full‑service operator on site
Gravity Rail: switching, transload (dry bulk, liquid, hazmat), car storage, repair, park‑owned shunt locomotives and track equipment, truck scale.

MRP / Energy Center

Prime power, steam and chilled water — made inside the park, sold by the hour.

Combined heat and power at industrial scale. High‑efficiency gas turbines generate electricity; integrated waste‑heat recovery turns the exhaust into steam; absorption chillers turn steam into chilled water. Overall energy conversion above 85%, N+1 reliability with battery ride‑through, and every service delivered to the tenant by pipe and wire under a 20‑year agreement.

Electricity$ / kWh

Utility / self‑gen > $0.14
MRP Energy Center < $0.10

CPS Energy (via FELPS) is the only regional utility option — no regional alternative exists for tenants. On‑site prime power removes the dependency.

Chilled water$ / ton‑hr

25%SAVINGS

Tenant chillers & towers $0.16
MRP Energy Center $0.12

Steam‑driven absorption chillers eliminate compressor electricity. Tenant avoids chiller and cooling‑tower capex and contracted maintenance.

Steam$ / 1,000 lb

68%SAVINGS

Tenant boilers $8.80
MRP Energy Center $2.80

Steam is a by‑product of turbine exhaust heat, delivered by insulated pipe — no boiler plant, no boiler labor, no boiler maintenance.

More than 100 district heating and cooling systems already operate across the US — including the San Antonio District Cooling Company downtown. The Energy Center brings that model to a manufacturing park: a typical 12+ month tenant construction period lets the plant add generation and thermal capacity ahead of occupancy, so N+1 supply is in place on day one.

Competitive position

Of 34 industrial parks surveyed in the corridor, one is energy‑enabled and dual Class I.

The alternatives in Greater San Antonio–Austin offer land, or a single carrier, or a substation. None offer on‑site generation, thermal energy and water rights with both railroads on the property.

Who it's for

Three routes to the same 1,000 acres.

High‑volume, rail‑served manufacturers and processors that use power, heat, cooling and water — and that add value to the park's ecosystem. Not standalone data centers.
