According to this article on, the Sierra Railroad is planning to use diesel train locomotives to produce power for California. Each of the 48 engines are expected to produce 2.1 megawatts of power for a thousand hours each year. Another key advantage to this plan is that since the “PowerTrains” are mobile, they can be taken to the areas that need power the most, so it doesn’t have to be routed across the state through our power grid.

Moreover, the company is going to fuel them with 100-percent biodiesel, a cleaner-burning vegetable oil equivalent of the familiar petroleum product.
