that was chosen in recognition of the extraordinary effort that was undertaken by firefighters to fight the fire. It arrived at the D&SNG in late October, 2020. It is currently stored in Durango awaiting to be put into service. Diesel engine #1203 is a type DE75CT diesel built by H.K. Porter in January, 1946, originally for U.S. Gypsum. It was acquired in March, 2017 from the Georgetown Loop Railroad in trade for GE 92-ton center-cab diesel engine #9. RB-1 (railbus) was built in the winter of 1987–1988. It was originally numbered 1001 and was named Tamarron. It could seat 32 people, had its own baggage compartment, had its own restroom and had a six-cylinder Caterpillar diesel engine. This unit was intended for use on the Animas River Railway; when that operation was shut-down, it was found being used as a switcher in the Durango yard. Years later, it was put into revenue service during the 2002 Missionary Ridge Fire. In April, 2020, it was announced that four MLW type DL-535E diesels have been purchased from the White Pass & Yukon Route in Skagway, Alaska. The first two of those diesels (Nos. 101 and 107) were delivered between late August and late September, 2020. The other two diesels (Nos. 103 and 106) were delivered in late September 2021. D&SNG rolling stock The Durango and Silverton Narrow Gauge Railroad currently operates over 50 pieces of rolling stock. Some of the cars are the oldest passenger cars in existence. Concession cars Like most of the coaches on the D&SNG, the concession cars are good examples of how coaches were renumbered and rebuilt several times by the D&RGW. Concession car 64 was originally D&RG mail-baggage 64 built in 1889. In 1983 it was purchased from the Black Hills Central Railroad. 64 returned to service in 1984 as a concession car. Concession car 126 was originally D&RG baggage car 27. It was renumbered 126 in 1886. It was converted to a coach-snack bar by the D&RGW in 1963 then reconverted in 1979 to a coach. It was reconverted to a full concession car by the D&SNG in 1982. Concession car 212 was originally D&RG coach 20 built in 1879. In 1887 it was rebuilt into a combination coach-baggage car and numbered 215. In 1942, 215 had been sold to a Mexican railway. Then the D&RGW realized that it was larger than another combination car 212.
