The Athearn HO Missouri Pacific EMD GP50 & GP38-2 Diesel Locomotives 3522 2160 is a replica of the iconic I have had these MP Diesel Locomotives in my HO Scale Storage since I got them for Christmas in the early 1990’s the year they were released. I have had a family history with MP Railroad and always loved anything MP. The set has never been out of the box or run on track. EMD GP50 and EMD GP38-2 locomotives in 1:87 scale. This model is ready-to-go with a B-B wheel configuration and features a dual color scheme of yellow, gray, and red, representing the Missouri Pacific corporate roadname. Equipped with an analog control system, this diesel locomotive is designed for operation on a two-rail system, making it perfect for model railroad enthusiasts aged 14 years and up.
