This Broadway Limited HO Scale This Broadway Limited HO Scale Streamlined 4-6-2 "Yellowjacket" Pacific is based on Chicago & North Western's last streamlined steam engines. As the railroad received streamlined passenger trains, it sought streamlined steam locos to haul them and the result was the Class ES Pacific steam locomotive. Built in 1930 by Alco, the ES locomotives were originally intended for the "400" fleet. However, before the engines were delivered, C&NW management decided to shift focus away from streamlined steam power and instead placed orders for new diesel locomotives from the General Motors Electro-Motive Division. As a result, the ES locomotives were reassigned to other passenger services until they were retired and scrapped in 1953. Crews affectionately nicknamed them "Yellow Jackets" because of their distinctive yellow and green paint schemes. The Paragon4 Series models feature Paragon4 sound and DCC, user-adjustable smoke rate, and integral GoPack capacitor for smooth operation during small losses of electrical contact. This model has wheels profiled to operate on Code 70 and larger rail and curves of 18" radius, but larger curves are recommended. The 4-6-2 "Yellowjacket" Pacific is part of the line of Broadway Limited HO Scale Paragon4 locomotives.
