A searchable list of scanned aperture cards of BN Structures in use in the late 1970s from mid-Montana to the Pacific Coast. Most were built by predecessor roads NP, GN, SP&S, plus a few Milwaukee Road et al. TO LOCATE DRAWINGS, use View menu at right to select your road, then place cursor over the header at the top of a column you want to filter (try "Station"). Click the down-arrow when it appears, then "Show Filter Choices" if necessary, and make a choice from the scrollable list that appears. You can filter multiple columns at a time. OR... simply type a word into the search box at upper-right.
Higher-resolution versions of these files are available to GNRHS & NPRHA members on request (or to the public for a modest fee). Contact
