Track for the Nevada Northern Railway was laid over a century ago, connecting one of the largest copper mines in North America to the Transcontinental routes to the north. Today, several of the original steam locomotives that were used over a century ago are still in operation. The Nevada Northern Railway is the best-preserved example of a standard-gauge short-line left in North America.
The 2025 NCKMS conference will include a geology-themed trip aboard this historic railway.
