Why it matters

Let loggers and miners run trains on rough, steep track; Shay locomotives went to 48 states and 24 countries.

Who gets the credit is disputed

The Ohio claim. Lima Locomotive Works built Shay engines from 1878 to 1945, turning Ephraim Shay's idea into thousands of working locomotives.

The other claims. Ephraim Shay was a Michigan lumberman who designed the engine. Counts of engines built differ by source: 2,761 in one, about 2,770 in another.

Sources

Confidence. Medium: the main facts were confirmed, but some details (often an address or ZIP code) were not.
