EMD GP38

A number of GP38s have been rebuilt into the equivalent of a GP38-2. Conversely, a number of higher horsepower 40 Series locomotives have been rebuilt into the equivalent of a GP38-2 (GP38AC), by the removal of the turbocharger and the substitution of twin Roots blowers. In 2007, Norfolk Southern rebuilt #2911 which is an ex Penn Central GP38 into an experimental zero-emissions Battery-Electric locomotive known as the Altoona Works BP4. The new locomotive was renumbered as NS #999. It has since been sold to Rail Propulsions Systems, where it was upgraded for eventual use in the Los Angeles Basin region. ==Preservation==
