- Athearn Model "Pennsylvania Railroad" Diesel Locomotive, 1945-1975 - HO or 1:87 scale trains first appeared after World War I but didn't become big sellers in the United States until the 1950s. Their smaller size -- half the size of O scale models -- allowed modelers to build more elaborate layouts in the same physical space. HO is large enough for realistic detail, yet small enough to remain affordable to many customers.
