Well here is one of my favorites, from the early MPC era at Lionel, 1973-74, the # 8303 Jersey Central "blue" Columbia 2-4-2. In those days Lionel was trying to re-establish itself in a much smaller market than today and selected the Columbia 2-4-2 , in a sense , to launch its efforts in steam trains again. It made the Columbia from 1970-1976 in both cataloged and uncatalogued units, in sets, for separate sale, and in quite an array of liveries. Lionel did use the Columbia in the postwar era as well especially in Scout sets and low end 0-27 sets and there are differences between postwar and MPC Columbia's but they are too detailed to discuss here. Most of the best features of the postwar engines were continued and new ones were added. In the case of the #8304 the big new feature is "Electronic Sound of Steam" and this was one of the first engines to have it.
So here is a stalwart, the Columbia 2-4-2 one of many sisters, ready to go to work (MPC wisely replaced the postwar Scout motor with a much more reliable spur gear motor in all these engines).
Hope your weekend will be great. Enjoy!
