Buildings and Structures of American Railroads - online book

I just came across a very interesting reference resource. This site has several digitized books by a Walter Gilman Berg, which feature plans and info about railroad structures:

One of the books is “Buildings and Structures of American Railroads”, and is a 1908 reference book for railroad managers, superintendents, etc.

There is also a similar book on American railway bridges and structures, and another on railway shop systems.

They can all be viewed online, downloaded to an ebook, or downloaded as a pdf.
