Beyond wires and batteries: Voltify’s new model for freight rail electrification

Freight rail is often described as the most energy-efficient way to move goods over land, yet it still runs on one of the dirtiest inputs in modern infrastructure: diesel. As rail operators face mounting pressure from volatile fuel costs, tightening emissions rules, and aging locomotive fleets, the question is no longer whether rail should decarbonize, but how.

One company argues the industry has been approaching the problem from the wrong direction. Voltify, co-founded by Daphna Langer, is pursuing a model that aims to leapfrog conventional electrification strategies, seeking to electrify freight rail without rebuilding the entire network or sacrificing operational range.

The Electrification Trap

On paper, the logic of electrifying rail is straightforward. Replace diesel locomotives with electric ones and connect them to clean power. In practice, freight rail in the United States spans roughly 140,000 miles of privately owned track, making full overhead electrification via catenary...

Even the most sophisticated AI (artificial intelligence) models are constrained by data trapped in information silos and legacy systems. The challenge is every new data source requires its own custom implementation, making connected systems difficult to scale, which is something that could slow building the next-gen infrastructure projects we so
