How to Ship a Rail Car or Flatcar by Truck: Complete Transport Guide

Rail Car Types and Dimensions

Rail cars vary significantly in size and weight depending on their type:

• Standard flatcars (50–60 ft): Weight 50,000–70,000 lbs. Width approximately 10 ft. Height approximately 4–5 ft above rail.
• Bulkhead flatcars: Similar dimensions to standard flatcars but with end walls. Weight 60,000–80,000 lbs.
• Gondola cars: Open-top cars for bulk commodities. Length 50–65 ft. Weight 55,000–75,000 lbs.
• Boxcars: Enclosed cars. Length 50–60 ft. Height 15–17 ft above rail. Width 10–10.5 ft. Weight 60,000–80,000 lbs.
• Tank cars: Cylindrical cars for liquids. Length 40–60 ft. Weight 65,000–90,000 lbs empty.
• Hopper cars: Open or covered cars for bulk materials. Length 40–60 ft. Weight 55,000–75,000 lbs.

Why Rail Car Transport by Truck Is Complex

Several factors make rail car transport by truck uniquely challenging:

• Length: Most rail cars are 50–65 ft long, far exceeding the 53 ft legal limit for standard trailers. This requires specialized extendable trailers or multi-trailer configurations with a jeep dolly.
• Width: Rail cars are typically 10–10.5 ft wide, exceeding the 8.5 ft legal limit and requiring oversize permits in every state.
• Height: Boxcars and covered hoppers can be 15–17 ft tall, requiring careful route planning around bridge clearances.
• Weight: Even empty rail cars weigh 50,000–90,000 lbs, which combined with the transport trailer often requires overweight permits.
• No tie-down points: Rail cars are designed to be secured by rail couplings, not by chains. Specialized blocking and bracing is required to secure them on a highway trailer.

Trailer Options for Rail Car Transport

• Multi-axle RGN with extendable deck: The most common solution for flatcars and gondolas. The extendable deck accommodates the car's length, and multiple axles distribute the weight.
• Lowboy with jeep dolly: For very long cars, a jeep dolly (a separate axle unit) is placed under the front of the car while the rear rests on the lowboy. This configuration requires careful weight distribution analysis.
• Specialized rail car transport trailers: Some carriers have purpose-built trailers designed specifically for rail car transport, with integrated blocking systems and optimized axle configurations.

Permit Requirements

Rail car transport almost always requires oversize and overweight permits in every state traversed. Width permits are required because rail cars exceed 8.5 ft. Length permits are required because the load exceeds 53 ft. Overweight permits may be required depending on the combined weight of the car and trailer. Many rail car moves qualify as superloads (over 150,000 lbs combined or over 16 ft wide), requiring engineering reviews, route surveys, and in some states, police escorts. Pilot cars are required in virtually all states for loads over 12 ft wide. IronHaul's permit team handles all filings and coordinates with state DOTs for route approval.

Loading and Securement

Loading a rail car onto a highway trailer requires specialized equipment — typically a crane or heavy-lift equipment to position the car on the trailer. The car must be blocked and braced to prevent longitudinal and lateral movement during transport. Standard chain tie-downs are supplemented with custom blocking systems. The car's trucks (wheel assemblies) may need to be removed or secured separately depending on the transport configuration.

Cost Factors

Rail car transport by truck is among the most expensive heavy-haul moves due to the specialized equipment, permit complexity, and loading requirements. Short moves (under 200 miles) typically run $5,000–$15,000. Long-distance moves (1,000+ miles) can run $15,000–$40,000+ depending on the car type, dimensions, and permit requirements. Crane or rigging costs for loading are additional. IronHaul provides detailed quotes that itemize all cost components.
