Global rail systems face a capacity and flexibility gap. Long freight trains are efficient for moving large volumes, but they are slow to reaccelerate, difficult to schedule flexibly and costly to shunt, especially on mixed-use lines, in dense terminals and on industrial sidings. Diesel shunting locomotives add emissions and additional maintenance costs, while building new lines is capital-intensive and slow to deliver. Przemek Ben Paczek, together with Łukasz Mielczarek, Paweł Radziszewski, Katarzyna Foljanty and Tomasz Kublin, is addressing these issues with the MagRail solution, a retrofit technology that upgrades conventional rail infrastructure with magnetic propulsion.
