Paragon(TM) Series Diesel E8B Powered w/Quantum(TM) Sound -- Union Pacific #931B w/Horizontal Grilles & Snow Shields

For long and heavy trains, additional power was often needed. While many roads used matching A units coupled back-to-back, some also purchased cabless booster units to provide a snappy, uniform appearance. Prepainted in authentic colors to match specific A Units (sold separately), models are available powered with sound, or as unpowered models.
