CSX, a major train company with 21,000 miles of tracks, is quietly and rapidly greening their entire operation. Tracks get lubed with a soy-baed substance now, not oil. Their engines are smarter and use much less fuel than standard diesels. They recycle oil and use it to heat their facilities. Lots more too.
Next time you sit at the intersection, watching the train go by, remember that it’s likely carrying the same as 280 trucks, and that each ton on there is getting 400+ miles per gallon.
An old-school industry is becoming cutting edge new, isn’t it?
