When trains traverse varying regions, the pronunciations vary too. How many ways are there to say "Kanawha"? Only one. But you almost have to be from there to know.
Here in New England we have the Berkshire Mountains. People from other parts of the country say "Berk-ShIre"... like Hobbits live there. But it's pronounced: "BERKshear" or "BERKshur". NEVER "Berk-ShIre".
There's a railroad in the Midwest that was called the Pere Marquette. I recently heard it called the Pierre Marquette! WHAT?!
Pere Marquette was named for the French Jesuit missionary "Father Jacques Marquette". There's no "Pierre" in there. Anywhere.
"Pere" is pronounced like the fruit: "pear".
