CSX Transportation and New York State Reveal Low Emissions Locomotive

The main point of the article was to let people know that the CSX and EPA teamed up to lower the Genset emissions locomotive in selkirk, NewYork. They want to tell people that their reducing the harmful emissions in that area. The Genset locomotive has three small engines and one large engine. The large engine can be turned on and off and is capable of reducing carbon dioxide emissions by 80%. It can also reduce carbon dioxide emissions by 25%. The author argues that the new Genset is the next generation of sustainable energy.
I thought that the article was interesting and information giving. I actually agreed with the article because it's trying to help the environment. I am wondering why this is not being used in other areas. They should try to help the environment every where not just in one area.
