The Friends’ Library/Archive/Museum is established as a repository of railroad-related materials and publications. These materials and publications specialize in the general railroad history of New Mexico and Colorado with a major emphasis on the narrow gauge railroads of the two states and narrow gauge elsewhere. Materials and publications include documents, letters, photographs, magazines, books, and other media on those topics.

The library is envisioned as a reference and research institution. This means the collections are open to interested members of the Friends. Non-members might be allowed access under specific and approved conditions. The librarian will respond to written requests for information and, in some cases, will provide copies made from materials in the collection, depending on the condition of the item. The librarian will open the collection to researchers upon request and at the convenience of the librarian and the requesting parties.

The Library is not a circulating library. No materials will be loaned.

Arrangements to access the library can be made by contacting the librarian via email at library@cumbrestoltec.org, or by writing to Friends of the Cumbres & Toltec Scenic Railroad, 6005 Osuna Rd. NE, Albquerque, NM  87109.
