"Does Amtrak currently use bio-diesel? I was reading about the trial run of the Heartland flyer back in the day when Amtrak was a charter member of the Chicago Climate Exchange. What were the results of that test? "
Best I could find is:
"Amtrak used a $274,000 federal grant to start a year-long biofuel experiment this month using beef by-products to power the Heartland Flyer, a route that travels from Oklahoma City to Fort Worth, Texas in an attempt to reduce emissions and find alternative fuels. So far, however, the experiment doesn't look like a sustainable alternative."

https://www.popsci.com/technology/artic ... r-train-us"what percentage of the electricity used by Amtrak comes from solar and wind power?"
Could not find pinpoint numbers my best guess would be 0% if we are talking about the acela and electric powered trains...might be solar panels charging batteries for various track side equipment.
