General Railway Signal Co's 1905 Electric Interlocking Catalog (page 11) gives a tabulation of interlockings in service on American railroads. Forty-one railroads had a total of 162 "plants," which had a total of 6153 "functions." (I'll leave it to you to interpret the word "functions.")

N&W is credited with one interlocking, having a total of 13 "functions."

Where was it ? When was it built?
