@RickO posted:Actually, it sounds like the I1s have Pennsy 3 chime like the M1s.
With 5 legacy whistles I imagine the banshee and 3 chime will be in the selection.
They probably will have both like you say. I don’t think that whistles were specific to the whole class. Nearly all Pennsy steam was built by two different shops. Altoona and Baldwin.
I imagine the whistles that were affixed were probably influenced by that fact, rebuilds and shop visits, and maybe even the preference of the crews.
That said, I don’t know for certain.
