The Modern Railroad

Two Evolution-Series locomotives with Chicago-bound shipping containers roll at the Roanoke, Virginia, signal. They pass a green light on a clear the track.
These modern locomotives, dubbed "world's cleanest locomotives" were designed with six years and $200 million of research and development by the modern railroad industry. At up to 4400 horsepower, these locomotives have no compromises at the draw bar while lowering emissions and increasing fuel efficiency.
The locomotives grind past.  Many sea containers cross the United States from the Atlantic to the Pacific as a land bridge in order to avoid Panama Canal congestion. Domestic containers belonging to the railroads and trucking companies are quickly pulled off of the train at the destination and are routed for distribution. Modern trains allow truck trailers to be removed from their chassis to become stacked two high, helping satisfy the world's need for fuel-efficient transportation.
The locomotives throttle up. The cars whine with precision over the steel rail. The train has momentum. This is the modern railroad. America is in motion.
