Five trains in operation at Disneyland Park in Anaheim, Calif., are running on biodiesel created from oil used to serve area tourists, an official says.

Disney Director of Environmental Affairs Frank Dela Vara said the biodiesel fueling five Disneyland Railroad trains was created from oils once used at the California resort's various hotels and eateries, The Orange County (Calif.) Register said Wednesday.

"The improvement here is that it's no longer using food for fuel. There are no soybeans grown in the Midwest to fuel our trains, just cooking oil that we're already generating," Dela Vara said.

The Disney official was referring to a failed 2007 attempt by the famed tourist site to use soybeans to create biodiesel for the trains. That environmental effort was scrapped by Disneyland in 2008 amid storage problems.

The Register said if successful, the new biodiesel effort that began Wednesday would one day be used to fuel Disneyland's Mark Twain paddlewheel steamboat and other on-site equipment.
