The Shootist (1976)
The marshal tells Books that Carson City is modernizing and he projected a bright future. At the time, the population was 2,893, which represented a decline of 50% over the past 20 years. This was largely due to the railroad bypassing the town, being routed through the Donner Pass, running some fifteen miles north of Carson. While modernization would take place, there would not be a significant increase in population until the mid-fifties. A century after this film the population had risen to 48,000. As of 2020, It is now the tenth largest city in Nevada.
Streetcars would continue to operate in Carson City through the 1950s at which time, due to the conversion of wartime manufacturing plants back to consumer goods and automobiles, the boom in auto manufacturing would lead to the disappearance of streetcars across the country. This was not just because of the availability of affordable cars but because General Motors went on a massive shopping spree, buying streetcar lines and shutting them down. This was the central plot device in the film Who Framed Roger Rabbit (1988).
