A customer forwarded this to me...
Seems Amtrak (US National Passenger Rail Service) is experimenting with B20 in one of their engines.
The Biodiesel is produced from beef tallow from cows from Texas.
More details here:
Amtrak is what got me into diesels in the first place (my father has worked for them since '79).
Trains got us both into diesels, diesels got us into Biodiesel, and now it's gone full circle with Amtrak experimenting with Biodiesel.
...beef-based biodiesel can efficiently run the Heartland Flyer passenger train between Oklahoma City and Fort Worth, Texas, and also reduce emissions.
Tallow from Texas cattle — fat often used in soap or animal feed — is supplying 20 percent of the fuel for the 3,200-horsepower engine, the rest is standard diesel. Previous engine tests showed that those running the B20 mixture produced less carbon monoxide and fewer particulates and sulfates.
