How is SEPTA not a Interurban?

Parts of SEPTA I would defintly consider Interurban…Like the Doylestown line and NJ Transit River Runner (Well maybe,)

On the other hand when I do ride the South Shore the conducters there consider themselves to be hard core heavy haul railroad employes with the scars to prove it!! The SOUTH SHOREs main mission was and still is to act as a heavy haul switching railroad to the steel mills in “DA REGION” which is why the B&O owed it…

C&O (not B&O) had a 94% interest in South Shore from about 1964 to 1980, based in part on the fact that South Shore served the two new steel mills at Burns Harbor, but also on coal deliveries to NIPSCO’s online power plants. South Shore did not directly serve US Steel at Gary or any of the other steel mills in the Calumet region.

The only parts of SEPTA that have an interurban background are the Norristown High Speed Line (ex-Philadelphia & Western) and Routes 101-102 (ex-Philadelphia & West Chester). The Doylestown line is ex-Reading.
