Shipping freight by rail is a key component of the overall shipping process, letting businesses move goods across long distances affordably. While trucks offer versatility and access to more destinations, knowing how and when to use rail services is important for any aspiring shipper. 

Key Takeaways

  • Shipping by rail is often more cost-effective than shipping by truck over long distances.
  • Carriers that ship via rail often use differential pricing, meaning rates vary depending on cargo type, distance, and demand.
  • Rail is more cost-efficient for bulk loads than small ones, and it's limited by rail infrastructure. Trucks are better for short-distance transit of smaller shipments.
  • Third-party logistics providers can help you combine rail shipping with other modes of transport, optimizing your freight shipment costs. 

This article explores the fundamentals of rail freight transport, including pricing, advantages, and disadvantages.

Shipping by Rail: Terms and Definitions

I’ll start by reviewing a handful of key terms and definitions that apply to most, if not all, forms of rail shipping.

  • Rail Freight Transportation: The process of moving commercial goods using trains.
  • Engine: The locomotive that powers the train. Usually located at the front, they are sometimes used as distributed power units (DPUs) to overcome steep grades.
  • Railcar: A specialized freight car designed to carry cargo.
  • Intermodal Transport: Using multiple modes of transport such as land, sea, and air during transit.
  • Drayage Container: A shipping container used for intermodal transport, moved by truck and train.
  • Bulk Freight: Unpackaged goods (often raw or lightly processed) shipped without packaging, such as grain, soil, and minerals.
  • Hump Yard: Known formally as classification yards, a train yard where cars are pushed down a small hill, or ‘hump’, into different rail lines based on their destinations.

Now that we have these terms in mind, let’s take a look at how rail companies determine shipping rates.

How Much Does it Cost to Ship by Rail?

The price of rail transportation in the United States is usually determined via a system called differential rate shipping. You won’t usually get a final price until some back and forth with a broker or carrier. However, a solid understanding of differential pricing can serve you well when looking for rail carriers.

Differential rates split the carrier’s shipping costs into two categories:

  • Fixed Costs: These include maintenance, rent, and costs not subject to short-term changes.
  • Variable Costs: Labor, fuel, and other costs that vary based on output and results.

To get an idea of how this works, assume a rail transport company has two shipments to pick up on a trip: one from a granite mine and another from a manufacturer of heavy machinery. While the mine operates like clockwork and has multiple carrier options, the manufacturer often has to meet short-term goals with little notice to serve their customers properly, and their shipping options are limited.

The trip will have fixed costs of $800 and variable costs of $200 for a total carrier cost of $1,000. Each customer pays an equal portion of the fixed costs ($400 a piece), but the rail company charges only 25% of the variable costs to the granite mine ($50) while charging the manufacturer the remaining $150.

An infographic titled “Variable Shipping Rate Costs Breakdown” containing data regarding how variable costs influence the price of shipping via rail. The graphic is divided into three columns, labeled (from left to right), “Customer”, “Fixed and Variable Costs”, and “Final Price”. The information presented in the graphic reads as follows:


Final Price
Customer: Granite Mine. Fixed Costs: $400. Variable costs: $50.00. Final Price: $450.


Heavy Equipment Manufacturer
Fixed: $400
Variable: $150
$550

Shippers should keep in mind that pricing information between carriers and their customers is usually confidential. Even if you do find out what a customer with comparable needs is paying for carrier service, your rate may be higher or lower depending on the previously mentioned variables.

Another factor to keep in mind is that over long distances, rail shipping costs tend to be lower than comparable truckload (FTL) and less-than-truckload (LTL) shipping. Trains can carry significantly more cargo with fewer resources, which means you could save hundreds of dollars per ton per mile on a similar shipment sent over the road.

Types of Rail Freight Transport

Given the variety of goods that travel by rail, carriers have developed a number of specialized train cars to make transport safer and more efficient. Some of these cars include:

  • Boxcars: Palletized and crated goods.
  • Flatcars:  Heavy hauls and oversize machinery.
  • Tank Cars:  Bulk chemicals, liquids, and other potentially dangerous raw materials.
  • Hopper Cars Grains, minerals, and other bulk commodities.
  • Refrigerated Cars (Reefers): Temperature-controlled units for perishable goods.

In total, 2023 alone saw over $203 billion dollars worth of widely-varied cargo moved across the railways of the United States. To help you determine if rail shipping should be part of your logistics plan, it’s worthwhile to know what goods and products benefit most from this mode of transportation.

What are the Major Types of Cargo Transported by Rail?

While almost any good or commodity can be shipped by rail, some make more sense than others due to shipment volume, size, or the type of cargo in question. Let’s break down

some of the most popular candidates for rail transport.

  • Bulk Commodities – Grains, minerals, and soda ash are easily transported in hopper cars, forgoing the need for immediate packaging.
  • Intermodal Freight – Full containers that are transferred intact between trucks, trains, and cargo vessels.
  • Perishable Goods – This includes consumables and pharmaceuticals.
  • Oversize/Over Dimensional Freight – Heavy equipment and parts or goods that can’t be broken down to standard shipping sizes and weights require this service.
  • Hazardous Materials – Chemicals and flammable substances can be transported more safely on a train car than a truck, since spills are less likely to impact population centers.

Even if your shipments don’t fall within these categories, you may find that rail freight transport should be part of your shipping strategy after thoroughly considering its advantages. 

Pros and Cons of Shipping by Rail

I’ve mentioned that rail transport is an effective way to move goods across long distances. Some specific advantages of this shipping method are:

  • Lower cost per ton-mile (approximately 75% lower) compared to trucks
  • More fuel-efficient, resulting in a lower environmental impact
  • Higher safety and security for cargo
  • Ideal for large-volume shipments
  • Reliable transit schedules due to dedicated rail networks
  • Reduced traffic congestion and less wear on roads

Conversely, shippers should be aware of the inherent limitations of rail transport.

  • Limited flexibility (restricted to railway infrastructure)
  • Not suitable for small cargo or short-distance shipments
  • Potential delays due to rail network congestion
  • Longer transit times compared to air freight

While rail freight transport offers significant cost savings and efficiency for large shipments, it’s rare to be able to use rail exclusively to ship goods. Instead, you’ll need to use intermodal shipping to address every point in the supply chain.

Intermodal Transport: Combining Rail, Road, Sea, and Air

Think about the overall journey of a product from a manufacturer to a distributor and, finally, to the end user. Unless the item was made within proximity to you, it probably spent time on at least two forms of transportation while in transit. This is intermodal shipping: the use of multiple shipping modes to move freight across the supply chain.

If you plan to ship nationally, you’ll need trucks, freight vessels, and even cargo jets at your disposal. Working with a third-party logistics provider will help you determine the fastest, most efficient way to move your shipments across the country.
