Colorado Narrow Gauge -- the final years. Colorado was once home to the largest interconnected system of narrow-guage railroads in the United States. Tonight's presenter, Russ Sharp, will cover the last two full years of narrow gauge operations (1967-68). Featured will be operations in the dual-gauge yard in Alamosa. From there we will follow freight action to Chama, NM and Durango, CO as well as locomotive servicing facilities in Durango and a trip on the SILVERTON. Although the gauge between the rails will be narrow, the coverage will be broad. We hope you join us for a most interesting evening.
