I would NEVER say SEPTA engineers aren't engineers.
Agreed, but the problem here is that SEPTA has acquired a reputation, fairly or not, of not being a 'real railroad.'
While I'm sure some of it is lingering (still!) resentment from the 1983 strike and its aftermath (in which many of the personnel with seniority left SEPTA for other railroads), SEPTA management and the SEPTA culture has a lot to do with it too. SEPTA is the only railroad in the nation that's operated by a bus company, and some of the things their management does are different from other railroads.
Worse yet in this respect is the culture where SEPTA doesn't
want to operate the railroad as a real railroad, and looks for every opportunity not to. Take for example Schuylkill Valley, where SEPTA was giving serious (millions of dollars of study serious) thought to running a 62-mile trolley line. You have to be really dead set against railroading to pursue a folly like that.
So (with some exceptions*) the current operating personnel are the victim of circumstances rather than doing anything to deserve that reputation.
*--then again some of the stuff I've seen SEPTA personnel do--like the engineer who decided to open the vestibule door and take a leak onto the tracks while his train was stopped to board passengers--makes me have second thoughts about that statement.
