Complexity and Risk in Freight Transportation

Rail transportation is an enigma. It is a throwback to a bygone era, bridging the North American continent after a civil war sparked by tensions that echo loudly today. Many trains in the U.S. appear to have changed little since that time. And yet in some parts of the world they feel like a wonder of modern technology, blasting through the countryside with unrivaled tranquility.

The movement of goods across vast distances is essential to life in the 21st century. Much of this movement happens on land. In the 19th century, most freight in North America moved painstakingly slowly on a rail network built by large private railroad companies. Connection to this expanding network was a key to economic success in the burgeoning industrial power. That changed with advances in internal combustion engines and federal investment in a highway system.

Today, trucks move the majority (64%) of freight in the U.S. [1] There are almost 4 millions miles of roadway, allowing motor carriers to provide near-nationwide door-to-door service. [2] Trucks also contribute the vast majority (almost 80%) of CO2 emissions in the U.S. They are both the most significant proportion of total freight emissions and one of the carbon-intensive modes of freight transportation—especially the growing short-haul and final-mile segments delivering online orders. [1]

Trains, in contrast, are over three times more fuel-efficient than trucks. Freight moved on the least efficient trains emit less CO2 per tonne-kilometer than the most efficient trucks on the road today. [3]

In an era where we expedite critical personal protective equipment from distant lands, and where the global logistics system readies itself for the monumental challenge of distributing the coming coronavirus vaccines, rail transportation seems like a rigid, unreliable artifact of the past, ill-suited to 21st century challenges.

And yet rail may, in fact, be an apt metaphor for the coming decade. It has withstood the test of past global pandemics, natural disasters, and civil and global wars; it has unmatched, transcontinental carbon efficiency; and perhaps most importantly, it has proven, untapped technologies to accelerate humankind to a brighter, greener future.

In a twist of fate, the systemic challenges we face with land-based freight is a microcosm of the challenges we are likely to face as a species in the coming decade.
