The Bachmann N Scale Roaring Rails Diesel Train Set brings the sounds of real railroading to you! An EMD GP40 diesel locomotive equipped with a Sound Value DCC and sound system pulls a 50' boxcar, 40' gondola and a steel extended-vision caboose on a 34 x 24" E-Z Track oval. You'll have fun using the E-Z Command(R) Control Center to honk the horn and ring the bell as this detailed diesel runs down the track. Featuring realistic sounds such the roaring diesel prime mover with realistic horn and bell in 16-bit digital sound, the Sound Value package is great for beginning and advanced modelers alike! The locomotive and all cars in the Roaring Rails train set feature body-mounted E-Z Mate(R) knuckle couplers and the set comes with a complete illustrated instruction manual.
