This Broadway Limited EMD E8-E9 A-Unpowered B set is based on the carbody diesels introduced during the streamliner era. It features full Paragon3 sound and DCC for realistic sound and motor control. The B unit is unpowered. The Paragon3 sound system works with all Broadway Limited Rolling Thunder(TM) advanced sound systems. Other features of this diesel locomotive include a heavy die cast chassis, smooth-running flywheel-equipped drive, directional lighting and magnetic knuckle couplers. The N Scale EMD E8 and E9 locomotives can be operated on all DCC systems as well as on standard DC railroads (with limited sound functionality). This model has wheels profiled to operate on Code 55 and larger rail.
