It is 1949 and a Pennsy H10 is doing some shifting and local freights. These dependable and versatile engines started showing up in 1913 as mainline freighters and many lasted until 1956.
How do I know this is an H10? The H8, H9, and H10 shared the same boiler and running gear, but they had different appliances. The H9 and H10 had the sloping external steam pipes from the smoke box to the cylinders, while the H8's were internal. The most noticeable difference between the H9 and H10 was the H9 had snifters where the pipe met the cylinder, and the H10 didn't. Since my Weaver model does not have the snifters (a round valve) it is an H10.
NOTE: Lionel is marketing their H9 as an H10. If you buy one of the H10s, hide the box and call it an H9.
