The sleeping giant of rail fuel conservation. No existing technology will save as much fuel long-term as chasing better aerodynamics — here's why, and what the data shows.
At freight speeds, a railcar spends a remarkable share of its energy simply pushing air out of the way. Close the gaps that create turbulence — voids along the roofline, spaces between dump chutes, the blunt faces of stacked containers — and you cut drag, fuel burn, and emissions in one stroke. The challenge is proving it, car by car, and making the modifications pay for themselves.
Something small can create a huge amount of drag. On the Wright Flyer, most of the drag came not from the wings but from the guy wires and struts. The same is true on a train: walkway supports, railings, and gaps between cars quietly dominate the air resistance. Find them, close them, and the fuel savings follow.
A 50-foot mach 0.2 subsonic tunnel pumps air past G-scale models at 100 mph, measuring velocity, temperature, and barometric pressure to compute each design's drag coefficient. Paired with CFD and a BYU engineering partnership, it turns hunches into measured, defensible results.
Tunnel results carry into the field: 112 life-size modified covered hoppers instrumented and run in high-mileage service confirmed a 4–7% fuel savings. Refrigerated boxcars, intermodal containers, and autoracks have all been assessed and improved the same way.
Railroads have committed to deep emissions cuts by 2030, yet fuel efficiency is improving only about 1% per year — far short of target. Aerodynamics is the proven, near-term lever that can deliver 5–10% reductions without waiting on a new fuel or a new locomotive fleet.
Deflectors, fairings, roof and side treatments, and screen systems retrofit existing fleets — the engineering behind six issued U.S. patents. Solutions like the Corrugated Metals Aeroscreen and roof/side riders make aerodynamic treatment practical at fleet scale.
The trucking industry's SuperTruck program showed what coordinated aerodynamic focus can achieve. Rail has even more to gain — long consists, high mileage, and decades of fleet life multiply every percentage point of drag reduction into real money.

How the rail industry can harness a proven path to fuel savings — and why the time to act is now.
Railroads have committed to ambitious science-based emissions targets for 2030, yet fuel efficiency is improving only about 1% per year — a pace that leaves the industry well short of its goals. This feature lays out the case that aerodynamics is the proven, near-term lever railroads have been overlooking: wind-tunnel and field results showing 4–9% fuel savings on covered hoppers, refrigerated boxcars, and autoracks; retrofit hardware like the Corrugated Metals Aeroscreen and roof/side riders; and the lesson the trucking industry's SuperTruck program holds for rail.

An independent consultant, inventor, and lifelong change agent for the North American rail industry — based in Omaha, Nebraska.
I'm Wayne Kennedy — founder of Kennedy Consulting and the person who started a fuel-conservation group at Union Pacific back in 2004.
For more than thirty years I've worked to make freight railroading consume less fuel and move more freight. At Union Pacific I built the railroad's first dedicated fuel-conservation program — a body of work credited with helping save over $1 billion in fuel expense and cut fuel consumption by roughly 12%. Along the way I designed and operated a 50-foot mach 0.2 subsonic wind tunnel, the only one of its kind in railroading, and partnered with Brigham Young University's engineering capstone program to accelerate aerodynamic discovery.
Today I work independently with railroads, suppliers, research institutions, and technology firms across North America — on aerodynamics, fuel conservation, GIS and fuel-flow mapping, emissions reduction, merger-impact analysis, and ROI studies for new locomotive and biofuel technologies. I hold six U.S. patents covering rail-car aerodynamics, drag reduction, and locomotive performance.
I'm a member of LMOA, I publish and speak regularly on rail fuel efficiency and sustainability. My approach is simple: data-driven, field-tested, and focused on results that move the needle.
A few of the things that keep me moving when I'm not consulting.
