Dive into an array of curated resources and historical documents

Explore Our Research Archives

The NPRHA Research Library gives you access to terabytes of information about many aspects of Northern Pacific Railway history. On the home page, you will see a set of ten tiles that break the content into the quickly selectable, high-level subjects:
Selecting one of these tiles takes you to another set of tiles that further breaks down the selected subject into detailed lists of information, photos, and documents. To help you find the right resource, each entry is described, whether it be a photographer’s collection, a roster of steam engines, or a system-wide list of stations.
Many of the resources display as tables or lists. Because there can be thousands of items in a list, scrolling to find the information you seek can be onerous. Fortunately, you can reduce the number of items displayed by using one or more filters, a powerful tool that quickly locates your targeted information.
To use a filter, simply go to the column headings at the top of the list, pick a column that you want to reduce to a few specific values to help isolate your information. Hover over the column name and a downward arrow will appear. When you click this arrow, you will be shown a list of all the choices. Selecting one or more choices will limit the rows displayed to ones containing those values.
You may use column filtering on multiple columns during a single search to further isolate the information you seek. If you have questions or need help, feel free to send a note to
