Take the right track to the future with the new WiFlyer Express HO starter set from WalthersTrainline! Delivering a perfect blend of hobby-quality trains and technology that'll appeal to kids of all ages, you run the train using most WiFi enabled Tablets, phones or other devices (required, not included)! For easy set-up and instant realism, there's a 38 x 54" (0.9 x 1.3m) oval of improved Power-Loc Track(TM) now with nickel silver rail, brown ties and gray roadbed (and we'll have more track available separately for future expansions!). Leading the way, there's a colorful GP15-1 diesel with a factory-installed sound and control decoder with diesel sound, horn and bell that pulls a matching caboose and three freight cars equipped with metal wheels and Proto MAX(TM) metal knuckle couplers. To get the fun rolling, a full-color copy of "Walthers Getting Started Guide" for new modelers, and complete set-up and operating instructions are all included.
