Externally, there was little differences between the three classes. The main differences were the cylinder bore sizes (24" for the H8, 25" for the H9, and 26" for the H10), which is hard to tell apart in our scale models.
The H10 class was primarily built for the PRR's Lines West, and so that will be my personal focus as the Chartiers branch fell under that region. After the 4-6-0 G5, the H10 was probably the second most-often-seen engine on the branch line. The Lines West version has a high-side tender, to increase its coal-carrying capacity.
Engine #8259 worked on the branch line until 1957.
