In Connection with Disney's Environmentality program, the Disneyland railroad as of it's early april rehab now runs on a BioDiesel mix. Disney has a booth at Fullerton Railroad days with various handouts for the kids, pictures and documents about the changeover. I was discussing with the cast member what other Attractions might be switched over. I asked about the subs which have always run on Diesel. They will be running Bio when the Reopen. The next thing they're looking at is the Mark Twain riverboat. The booth is right next to the C.K. Holiday and the Kalamazoo handcar if you're in SoCal and have a free day tomorrow, it would be worth checking out these original Disneyland attractions.
