** This was my father’s – it has not been tested. Thanks for looking! The Athearn Norfolk and Western 34014 HO Diesel Locomotive is a ready-to-go model that accurately replicates the G.E.U.-28-30-33B design in blue and yellow colors. This 1:87 scale locomotive features a Bo-Bo wheel configuration and is made of plastic and metal materials. With an analog control system, this model is perfect for ages 8-11 and operates on a two-rail system. The locomotive also includes a flywheel drive feature, making it a great addition to any model railroad collection with a transportation theme.
