Crown Metal Products was a manufacturer of railroad rolling stock based in Wyano, Pennsylvania. The company was founded by Ken Williams in 1946 and initially sold pot cleaners and then electric fence wires and other products. In 1959, the company began to transition into producing narrow gauge locomotives, a personal interest of Williams. The company went on to produce steam locomotives and passenger cars of various sizes for amusement park railroads. The firm ceased production in 1989; however, much of its rolling stock continues to operate at various locations around the world.
