The magic ingredient: soybean oil.
Since January, the four operable trains that run along the Disneyland Railroad have been injected with the orangey-yellow liquid (resembling apple juice), with workers slowly weaning the steam locomotives off of ultra low sulfur diesel. The trains are now a mix of 2 percent diesel and 98 percent soybean oil, known as B98.
It's a move that more and more companies are undertaking as legislators stress "green" alternatives in the face of climate change reports and dependency on foreign oil.
For Disneyland, the switch to biodiesel saves as much as 150,000 gallons of diesel fuel each year, while potentially reducing carbon dioxide emissions by up to 80 percent, Disneyland Resort spokesman Bob Tucker said Monday.
"The decision, once we knew the trains would perform well, was an easy one," said Frank Dela Vara, technical director for Disneyland's Environmental Affairs.
