? Designed by the USRA for service during WWI, the 4-8-2 Mountain proved to be equally at home in passenger and fast freight service. ? Based on the Light version of the popular prototype, this ready-to-run model features excellent detail, including cab interior with glowing firebox, working headlight and many separately applied parts. The engine is DCC-ready, while a powerful can motor with flywheel provides plenty of pulling power. A hidden belt drive provides realistic see-through clearance between the boiler and frame. ? ?
