The short answer is not exactly.

The drawing you posted is from the Historic American Building Survey (HABS), which seeks to document and illustrate sites of importance, often historic areas in National Parks and National Landmarks and often in National Forests. The drawing standards are rigorous and developed by the National Park Service, and the drawings themselves are often prepared by Architecture and Engineering students and related professionals.

Those preparing the drawings may have an interest in the subject matter, but may not be an expert themselves. For example, there is probably a drawing of the Hamilton Grange in Manhattan, and the person drawing it may be an engineer but not know much about Alexander Hamilton specifically. I note the absence of information inside the bounds of the engine house where investigation by Joe Crea and Jerry Hoffer published in Slim Gauge News about 1970 indicated evidence of a turntable, water tank and coaling platform.

Your best bet for a similar drawing will be the Interstate Commerce Commission valuation maps prepared by the railroads. The Colorado Railroad Museum used to sell these: you will have to purchase the whole pack for the Clear Creek line. They are about 12" tall by 36" long (this is the reduced form!), and you will derive hours of enjoyment noodling over culvert locations, odd notes, and more right-of-way ephemera than you probably realized.

Good luck!
