While researching the Strasburg Lionel 0-8-0, and flipping through the Loco.
Cyclopedia, I noticed the Chicago and Illinois Midland 4-4-0. which is a high
stepping, slim little loco, that I think I read was the last "American" wheel arrangement built. That got me to thinking about the Columbia 2-4-2's that populated all the Marx #999 and Lionel Scout and other sets in years past. No 2-4-2's did I see in the Cyclopedia, but somewhere I have seen a prototypical one pictured. A 2-6-0 for export is about the smallest tendered critter shown. Since they had their own name designation, "Columbia", there must have been more than just a few. Maybe Cyclopedias prior to 1941 showed them or ? Wonder where and what roads ran them?.....I think the one
I saw was shown in the 1880's. (not 2-4-2T tank engines which are shown)
