Move freight forward with confidence
Your team already knows how to run a reliable operation. IntelliTrans gives them the clarity, tools, and support to do it with greater confidence and control.
There are currently 540 freight railroads operating across the United States. Seven of them are classified as Class I carriers, defined by annual operating revenue exceeding $447 million. These seven railroads - BNSF Railway, Canadian National, Canadian Pacific, CSX Transportation, Norfolk Southern, Union Pacific, and Kansas City Southern - collectively operate 95,000 miles of track and employ over 194,000 personnel.
For most bulk shippers, Class I railroads handle the majority of long-haul movement. Their reach, capacity, and rate structures dominate the landscape, and their performance directly affects your transit times, demurrage exposure, and cost per carload.

For most bulk shippers, Class I railroads handle the majority of long-haul movement. Their reach, capacity, and rate structures dominate the landscape, and their performance directly affects your transit times, demurrage exposure, and cost per carload.
Beyond the Class I carriers, roughly 533 Class II and Class III railroads (also called regional and short-line carriers) operate an additional 43,000 miles of track and employ approximately 27,000 personnel. These carriers typically serve local industries and connect to Class I mainlines, often handling the first or last miles of a movement.
For shippers located away from Class I mainlines, short-line relationships are critical. Your rail logistics team needs to understand which short-line serves your facility, how their interchange agreements work with Class I carriers, and what their service windows look like - because a delay on a short-line can cascade into missed Class I connections.
Rail is not a universal freight solution - it is purpose-built for specific commodity profiles and volume levels. Understanding the commodity mix tells you where rail shines and where it faces limitations.
Coal remains the single largest commodity by tonnage, accounting for approximately 33% of rail carload traffic. Chemicals follow at 12%, grain at 8%. But the revenue picture is different: intermodal traffic accounted for roughly 24% of revenue for major U.S. railroads in 2017, surpassing coal as the top revenue source.
Other commodities with significant rail volume include forest products (pulp and paper), motor vehicles, metals and metallic ores, crushed stone, sand and gravel, and petroleum products. If your business moves any of these commodities, rail is not a backup option - it is the backbone of your supply chain.
A rail yard is a complex series of tracks for storing, sorting, and loading or unloading railcars and locomotives. Understanding how yards operate - and where your cars sit in that process - is essential for managing transit times and avoiding demurrage.
Not all yards serve the same function. The major types your logistics team will encounter include:
Freight trains are not picked up and delivered as a unit. Individual railcars from multiple shippers and origins must be assembled into trains sorted by destination. This is done in classification yards.
The locomotives that pull those trains range from 2,500 to over 7,000 horsepower. Smaller yard switchers move only a few cars at a time within terminals. High-horsepower road engines handle long-haul movement, pulling trains of 50 to 100 cars or more across hundreds of miles. The type and number of locomotives assigned to a train affects its speed, tonnage limits, and how quickly it can depart a yard.
The train-building process is why transit times in rail are rarely as predictable as truck. A car may sit in a classification yard waiting for enough cars to build a train to its destination. Understanding this reality helps your team set accurate internal expectations and gives your planners the context to anticipate delays before they become demurrage charges.
When following up on a delayed car or coordinating a local pickup, your team will interact with railroad personnel whose roles directly affect your freight. The most common:
One of the most common sources of delays and cost overruns in rail logistics is equipment mismatch - either ordering the wrong car type or failing to confirm availability of the right equipment before a shipment is tendered. As of 2018, there were an estimated 1.67 million freight cars in service across North America. Of those, 53% were owned by lessors (leasing companies), 19% by the railroads themselves, 18% by shippers, and 10% by TTX, a jointly owned subsidiary of the Class I railroads. For bulk shippers, that ownership distribution means the majority of available equipment flows through leasing relationships, making fleet management and lease utilization a significant cost lever. Here is a practical overview of the eight primary railcar classifications:
For bulk shippers specifically, covered hoppers, tank cars, and gondolas are the most common equipment types. Each carries important compliance requirements - particularly tank cars, which must meet Department of Transportation specifications and, for hazardous materials, require double shelf couplers.
Managing rail freight effectively is not just a matter of booking cars and waiting for delivery confirmations. The operational complexity of the network means that proactive management, real-time visibility, and exception-based decision-making are what separate shippers who control their rail costs from those who absorb them.
The most common sources of preventable cost in rail logistics include:
Each of these cost drivers is manageable with the right data and the right workflows. The challenge for most rail logistics teams is that the data exists across multiple carrier systems, EDI feeds, and internal spreadsheets - making it difficult to act on in real time.
Rail logistics management is one of the most operationally demanding disciplines in supply chain. The network is opaque, the rules are carrier-specific, and the cost of mismanagement - in demurrage, missed deliveries, and fleet inefficiency - compounds quickly.
IntelliTrans TMS is purpose-built for bulk and break-bulk shippers who depend on rail. With deep integrations across Class I railroads and regional carriers, real-time car tracking, automated exception management, and embedded freight audit tools, your team gets the visibility and control they need to operate proactively - not reactively.
If your rail logistics operation is still relying on carrier websites, spreadsheets, or manual tracking, it's worth seeing what a purpose-built rail TMS can do for your team.
