From Chicago, and Railway Age's Rail Insights Conference and Expo today, June 8: William C. Vantuono, Editor-in-Chief, Railway Age: What is the status of Norfolk Southern's compressed natural gas (CNG) locomotives?
C. Douglas Corbin, Assistant Vice President Mechanical, Norfolk Southern Corp.: We built one prototype. We are sticking our toe in the water now with the CNG locomotive. We’re dabbling in it, I don’t see we will be building additional units currently. We’ve also looked at newer battery tech potentials. We are working with Penn State on one. There are some battery tech possibilities out there, but it's pricey.
