This table cross references Pennsy electric locomotives by class, type, sub class, sub class designator, year of introduction, and availability of HO scale models.

Eventually, clicking on minor class number will link to a class-specific page which will include prototype builder data, specifications, unit rosters, and unit photos.

Corrections and additions to this page are welcome. However, please refrain from submitting roster and subclass information for classes whose class detail pages have not yet been created. Thank you.
