The Athearn Genesis Missouri-Kansas-Texas Freight F-3A/F-3B/F-3A is a ready-to-go pre-built model replica of an Electro-Motive Diesel (EMD) locomotive. Made of plastic and designed at a 1:87 scale, this diesel locomotive is suitable for model railroads and trains enthusiasts aged 17 years and up. This unit features a vintage design from the 2000-2009 time period and is painted in the classic transportation theme. Standing at 2 inches tall, this locomotive is a detailed addition to any model railroad collection. It's fairly heavy, so that is what drove up the shipping costs.
