Parallel Systems has been selected to receive $4.5 million from the Department of Energy for an advanced testing program of its autonomous, battery-electric rail vehicles. The startup, which has raised more than $53 million to date, was founded by former SpaceX engineers to reimagine the rail system by creating a more efficient, decarbonized freight network. Matt Soule, Co-founder & CEO of Parallel Systems, joined Cheddar's Opening Bell to discuss what the company hopes to achieve.
