Нашёл упоминание лишь об одной сохранившей нетуристической узкоколейной железной дороге в США. Упомянута как ЕДИНСТВЕННАЯ в стране.

----------------------------
USG operates an active narrow gauge railway, the last industrial narrow gauge railway in the United States. The 3 ft (914 mm) gauge line runs north for 20.5 miles (33 km) from the plant at Plaster City (formerly known as Maria) to the gypsum quarry. The line hauls gypsum rock from the quarry to the plant. Various sources show the total mileage of the track between 15 and 26 miles (24.1 and 41.8 km).
