Vintage Marx O Gauge Southern Pacific 6000 Tin Litho Diesel Locomotive A-B Set

This vintage Marx O gauge Southern Pacific 6000 diesel locomotive A-B set is a classic piece of mid-century toy train history, styled after the EMD F-unit with the iconic red and silver Southern Pacific livery, printed portholes, grilles, and door details, and black plastic horns on the roofs; the set includes the powered A-unit and the dummy B-unit, meaning one locomotive runs the motor while the other is designed to be pulled behind it without power of its own; both pieces show the fair, honest wear you'd expect from toys of this age, including surface scratches, scuffing and fading on the bodies, some chipping along the edges, and general patina from decades of play and storage, but they remain structurally solid and display beautifully together as-is for a collector, restorer, or anyone building out a vintage O gauge layout; if you're interested in additional cars to go with this set, please reach out before or after purchase and I'm happy to put together a bundle and combine shipping to save you money; sold as pictured, please review photos closely as they are part of the description, and reach out with any questions before bidding or buying.
