The Lionel 6-19122 through 6-19127 D&RG California Zephyr 6-Car Aluminum Passenger Set is a vintage replica of Santa Fe passenger cars, made of extruded aluminum in a silver color. These passenger cars are ready to go with analog control systems and light functions, designed for O gauge railroads. Manufactured in the 1990s in the United States, these pre-built set features a transportation theme and are perfect for collectors aged 17 years and up. The set includes four passenger cars with a corporate road name of D&RG, adding authenticity to model railroads and trains enthusiasts’ collections. Mint, un-run 6-Car set. Not removed from boxes nor displayed. Please see my other actions for mor trains from my 35+ year collection.
