Here's a web page for you: (albeit on the Philadelphia, Germantown and Norristown Railroad)
It would appear to me that the PRR station would have been accessed by Shawmont Ave.

"The oldest train station in the United States, dating to 1834 is Shawmont station
(see photo) in the Shawmont section of Roxborough and is along the line used to Norristown. It represents a time when the train station was the home of the person responsible for tending it (Stationmaster). It had a waiting room, baggage room, post office and living quarters. One could get something to eat there as well. Many of the early stations functioned that way. With little parking and a short platform, the station was closed in 1990; however, the train still goes by as it did in 1835, and stops at nearby adjacent stations (Ivy Ridge and Miquon). Just imagine-over 1,500,000 trains have passed by Shawmont station.
The stagecoach-style passenger coach eventually became an enclosed coach with a wood-burning stove. The wood burning engine became a coal-burning engine and the 30-lb. rails were enlarged to 50 pound to accommodate larger, heavier and faster engines. "
