Railroads Between Pittsburgh and Duluth: Not Built from "W"

The premise is incorrect. Railroads linking Pittsburgh, PA and Duluth, MN were not built from "W" (whatever that refers to).

Actual History

• Pittsburgh: Hub of Pennsylvania Railroad (PRR), Baltimore & Ohio (B&O), others—heading west
• Duluth: Terminus for Northern Pacific (NP), Great Northern (GN), Duluth, Missabe & Iron Range (DM&IR)—heading east/west
• Connection: Lines built toward each other; key junction at Altoona, PA (PRR's Horseshoe Curve, shops)
• Transcontinental links: Completed via Chicago (major gateway) and northern routes (NP/GN to Pacific Northwest)

No single railroad directly connected Pittsburgh-Duluth. Traffic moved via Chicago or through-cars on multiple roads. The "W" reference is unclear—possibly a typo for a specific railroad, survey point, or person.
