At the University of Minnesota, the Coalition for Sustainable Rail (CSR) is actively converting a 1937 locomotive, # 3463, into what will be the world’s first carbon-neutral high-speed locomotive. It will not be electric, running instead on steam generated by the burning of biofuel, or torrefied bio-coal.
The fuel will be produced by the University of Minnesota’s Natural Resources Research Institute (NRRI).
Due to the abundance of sustainable forest in Minnesota and the energy efficiency of the torrefaction process (to subject to intense heat), bio-coal can be produced at reasonable cost. Not as cheap as current domestic coal, price range is lower than the diesel fuel powering all diesel-electric fleet of engines.
Featuring a gas-producer combustion system, improved steam circuit, modernized boiler, low-maintenance running gear and steam-powered electric generator, CSR anticipates # 3463 will be able to pull a passenger train with electric-like performance for less than the cost of diesel-electric locomotives. In order to prove the viability of bio-coal and modern steam technology, CSR plans to test the locomotive at speeds in excess of 130 miles per hour. CSR has named this “Project 130.”
