PRR Chartiers Branch - Topography
At Carnegie, PA, the branch starts at 770 feet above sea level. At Washington, PA the elevation was 1060 feet. Most grades were less than 1%. The track follows in the valley of the Chartiers Creek. The reason why I became interested in modeling this branch was the fact that it crossed the Chartiers Creek 19 times in the 23 miles, and it included one 500-foot long tunnel ("Greers" tunnel near Bridgeville). Outside of the towns the scenery is mostly rolling hills with lots of wooded areas; just my cup of tea.
