Wood trestles, bridges and grades

 Great Stuff Jim!

Indeed, great picture Jim!

From  sometime back in a Google Search for special collections I have the following notes from CSU

Colorado & Southern Engineer's Office (1923)
The Colorado & Southern Railway list of Bridges, Trestles and Curves, South Park Division
Gives bridge number numbers, kind, length and height as of June 20, 1918

and a similar book for the Denver Gunnison,  DL&G Bridges and other structures
November 1, 1894

Has anyone seen these books?

[Jeff Young]

Hi Ron,

I have parts of the D&RGW 1923 roster (which lists ice houses, telegraph offices, engine houses, scales, turntables, freight cars, MoW equipment, etc. — pretty much everything except bridges and trestles), but I’ve never seen one for the C&S.  Do you have a link?

Cheers,

Jeff.

Sorry no link.  I do not remember what words I used for my search.
Googling "Special Collections / Colorado / Photographs" have drawn a blank

You might try looking up Worldcat-listings of various photos,maps,books,and documents and what library they are in.

To return to the original question, the bents would always be absolutely vertical, regardless of the grade.  From a structural engineering perspective, you want those bents to be in pure compression, no bending moments, else they may be inclined to buckle and fail.

Evidently the D&RG had also purchased the same design of truss as seen in these images in of the Black Canon of the Gunnison.
