Description: Field books were used by railroad engineers to take notes as they surveyed the land for railroad construction. These books included vital information that described the lay of the land like topography and cross section notes. Some books also contain information on the placement of future railroad tracks, such as line, level, and switch notes. Each of these books was highly unique to the engineer that wrote in them, and no two are alike.
This specific set of three books are all by the same engineer and include details about laying track over difficult mountainous terrain. The tracks were built as switchbacks, which are zig zag shaped lines designed to climb the sides of mountains, and lead to tunnels.
Our books were originally archived in the Chicago, Burlington & Quincy (CB&Q) Lines West Engineering Office Field Book Files.
