Explore the network behind North American freight.
See the railroads, ports, terminals, transload facilities, warehouses, trucking providers, rail services, and freight infrastructure that connect freight across the United States, Canada, and Mexico.
Freight network
Freight moves through relationships, not isolated locations.
A railroad connects to terminals. Terminals connect rail and truck. Ports connect ocean freight to inland networks. Warehouses, transload facilities, carriers, and service providers support the movement between them. Commtrex brings those pieces into one connected freight network.

NETWORK RELATIONSHIPS
One freight location can connect to an entire network.
Start with a railroad, port, terminal, facility, provider, or market and follow the transportation relationships around it.
TRANSLOAD FACILITY
Example operating location
- Rail-served · BNSF
RAILROAD
DOCUMENTEDDocumented rail service. Direct service shown separately from connecting service.
- Highway access
HIGHWAY
DOCUMENTEDDocumented access. Otherwise shown as proximity, e.g. Interstate · 1.2 mi.
- Port · 12 mi
PORT
PROXIMITYNearby freight gateway. Proximity does not establish access.
- Storage facility · 3 mi
WAREHOUSE
PROXIMITYNearby storage, operated separately.
- Drayage · Example Carrier
TRUCKING
DOCUMENTEDService providers, where a relationship is documented. No fixed location implied.
- Industrial property · 2 mi
INDUSTRIAL PROPERTY
PROXIMITYNearby freight-oriented real estate. A property, not an operating facility.
A nearby freight asset is not automatically connected to the location.
Document the relationship. Map the proximity. Keep the two distinct.

Network FAQ
Exploring the Commtrex network
What is the Commtrex Network?
The Commtrex Network brings together freight infrastructure, operating locations, transportation networks, service providers, and industrial properties to help users understand how freight moves and who can support it.
What can I explore in the network?
Users can explore railroads, ports, terminals, transload facilities, warehousing and storage locations, trucking providers, rail services, industrial properties, and other freight infrastructure represented in Commtrex.
Does a location near a railroad mean it is rail-served?
No. Railroad proximity and documented rail service are different. Where service information is available, Commtrex keeps documented relationships separate from geographic proximity.
Does a facility near a port or terminal have access to it?
Not automatically. Geographic proximity does not establish an operational or commercial relationship. Access should only be represented when supported by documented information.
Does Commtrex cover the entire United States?
Commtrex represents freight infrastructure and service providers across North America, including the United States, Canada, and Mexico. Coverage varies by location, service type, and available data.
Can I use the network to find freight capacity?
Yes. Network exploration can help identify relevant freight locations and providers. Users with a specific service or capacity requirement can continue into Commtrex Find Capacity to pursue that need.
Are industrial properties part of the network?
Industrial properties can be explored alongside the transportation and freight infrastructure around them, but properties remain distinct from operating freight facilities and service providers.
Can freight providers appear in the Commtrex Network?
Commtrex represents freight providers and operating locations across multiple service categories. Provider information and participation depend on the provider type and the data available to Commtrex.
