They make compatible systems. The Illinois Railway Museum supports both pan and pole operations, for example.
Pantographs are better, but we can't just rip the band-aid off. It'll be better to slowly transition, line by line.
All that matters insofar as motors is that the overhead lines run at the same 600 V DC.

The 23 historically ran from 10th/11th and Oregon to Chestnut Hill West via 10th/11th and Germantown Avenue. At different points in its history it used the Germantown Carhouse (since gone) and the Luzerne Carhouse (not accessible by trolley anymore).
