From Richard Crabtree on Frisco Rails Across Missouri. Here we have an ad for a Frisco Fleet of Flashes featuring Frisco Nos. 4305, 3408, 4302, all 4-8-2 Heavy Mountain Class locomotives built at the Frisco West Shops in Springfield, Missouri between 1936-37. You could catch the St. Louis Flash, Kansas City Flash, or the Dixie Flash.
