How to Ship a Locomotive: Railroad Engine Transport Guide

Locomotive Weight and Dimension Ranges

Locomotive transport requirements vary dramatically by type and model:

Locomotive Type	Examples	Weight Range	Typical Width	Typical Height
Industrial Switcher	GE 44-ton, EMD SW1200	44,000–120,000 lbs	9–10 ft	13–15 ft
Vintage Steam Engine	Various heritage/museum units	28,000–200,000 lbs	9–11 ft	13–16 ft
Short Line Diesel	EMD GP38, GP40	240,000–280,000 lbs	10–10.5 ft	14–15 ft
Modern Freight Locomotive	GE ES44AC, EMD SD70ACe	400,000–432,000 lbs	10–10.5 ft	15–16 ft

Because virtually all locomotives exceed the 80,000 lb GVW federal threshold and most exceed 8'6" in width, locomotive transport almost always requires overweight and oversize permits. Modern freight locomotives are superloads by definition.

Trailer Selection for Locomotive Transport

Industrial Switchers and Lighter Units (Under 120,000 lbs)

Smaller industrial switchers and some vintage steam engines can be transported on a multi-axle RGN trailer (5–7 axles). The RGN's low deck height (18–24 inches) is essential for managing the locomotive's height within permit thresholds. Key considerations:

• Locomotive wheels must be blocked and secured to prevent rolling on the trailer deck
• Wooden blocking on the lowered RGN platform prevents shifting during transit
• Heavy-duty chain and belt strapping through designated lift points

Short Line Diesels (120,000–280,000 lbs)

Short line diesel locomotives require specialized multi-axle lowboy or RGN configurations with 7–12 axles. These loads are classified as superloads in most states, requiring:

• Route surveys to identify bridge weight restrictions and clearance issues
• Engineering review of bridge structures along the route
• Law enforcement escorts in most states
• Advance notice to state DOTs (typically 5–10 business days)

Modern Freight Locomotives (400,000+ lbs)

Modern freight locomotives at 400,000–432,000 lbs are among the heaviest loads moved on U.S. highways. Transport requires:

• Specialized multi-axle platform trailers with 20+ axles to distribute weight within bridge formula limits
• Comprehensive route surveys including bridge structural analysis
• Possible temporary road closures and utility line lifts
• Law enforcement escorts in every state
• Advance notice of 2–4 weeks to state DOTs
• Possible partial disassembly (removing trucks/bogies) to reduce weight per move

Route Planning for Locomotive Transport

Route planning for locomotive transport is far more complex than standard heavy haul. Key factors:

• Bridge weight ratings: Every bridge on the route must be evaluated against the load's weight distribution. Older bridges on secondary roads may require detours adding significant mileage.
• Tunnel clearances: Locomotive height (13–16 ft) combined with trailer deck height can create clearance issues at tunnels and underpasses. Route surveys must identify all low clearances.
• Utility lines: Overhead utility lines may need to be temporarily lifted by utility companies for very tall loads.
• International routing: Some locomotive moves route through Canada to avoid specific U.S. bridge or clearance restrictions — requiring additional border crossing permits and Canadian provincial permits.
• Railroad crossings: Ironically, moving a locomotive by truck requires careful management of at-grade railroad crossings, which can create clearance issues for low-deck trailers.

Securement Requirements

Locomotive securement requires specialized techniques:

• Wooden blocking on the trailer deck to prevent the locomotive from rolling (wheels are not locked)
• Heavy-duty chain through designated lift/tie-down points on the locomotive frame
• Belt strapping over the locomotive body to prevent lateral movement
• Blocking between the locomotive and trailer sides to prevent lateral shift
• Documentation of all tie-down points with photos before departure

Permit Timeline for Locomotive Transport

Locomotive transport requires significantly more lead time than standard heavy haul:

• Standard oversize/overweight (under 150,000 lbs GVW): 3–7 business days for multi-state permit packages
• Superload (150,000–300,000 lbs GVW): 1–3 weeks including route surveys and engineering review
• Extreme superload (300,000+ lbs GVW): 2–6 weeks including bridge structural analysis, utility coordination, and law enforcement scheduling
