N&W Pacific = Pensy K4?

[NW Mailing List]

Hanging in the lounge at the Raleigh, NC passenger station is a 
photograph of an N&W pacific (probably #503?) at Durham, NC.  Looking at 
the photo, it struck me how much like a Pennsylvania K4 Pacific it 
looks.  With the exception of the distinctive tender, I could almost 
believe I was looking at a Pensy engine.  Did the N&W and Pensy share 
locomotive designs, or is it merely a case of accidental similarity?

I took a photo of the photo, and can send it if it would help, though 
the quality isn't the greatest.
