Regarding The Black Hills Central Railroad. National Register Statement of Significance excerpt:
The Burlington and Quincy High Line Hill City to Keystone Branch is historically significant for its role in the development of the American frontier specifically the Black Hills of South Dakota. This isolated line that the Black Hills Central Railroad operates today is the only remnant left of the 106.4 mile Burlington and Quincy High Line from Edgemont, SD to Deadwood, SD. The rail line serviced the mines, lumber industry and hauled passengers from its construction in 1890-91 to 1983. The construction
of the Hill City to Keystone spur began in 1893 and has been operating continuously to present day. Dating back to 1956 the rail line is also the oldest continuously operating tourist train that runs on an original railroad line. The equipment, yard in Hill City, and track to Keystone are well preserved and carefully maintained; they also represent the physical manifestation of America’s quest to grow and prosper.
