People who buy train sets are looking for simplicity. They want to buy one box, set up its contents easily, and get running trains right away. Walthers is answering that need with new technology, offering three new train sets that operate via a digital throttle using a smartphone, tablet, or similar Wi-Fi device. The HO scale WiFlyer Express train set comes with an oval of track, a sound-equipped Electro-Motive Division GP15-1 locomotive, three freight cars, a caboose, and a Wi-Fi receiver.
