History corner

Why No. 21 looks so good. The Santa Fe Warbonnet paint scheme is one of the most famous designs in railroading. Created for General Motors streamlined diesels in the late 1930s, the red bonnet and yellow trim over stainless or silver tones became the visual identity of Santa Fe’s premier passenger service. Marx captured that look in tin litho, using bright inks and detailed screens to suggest vents, louvers, grilles, and windows without separate parts.

About Marx. Louis Marx and Company was America’s volume toy maker from the 1930s through the 1960s. Marx specialized in affordable, durable toys with smart manufacturing. For trains, that meant tin lithography on steel shells that could survive playrooms and still look great generations later. Marx O gauge sets introduced thousands of families to the hobby and remain a cornerstone of postwar collecting today.

Display and layout ideas

  • Pair behind a powered Santa Fe A-unit for a classic A-A consist

  • Add a string of tinplate coaches or period freight for a 1950s mixed train look

  • Create a restoration project. Gentle cleaning, selective wax, and careful detailing can transform this into a standout shelf piece

  • Keep the patina. Many collectors love the “played with” authenticity of mid-century tinplate

Care and restoration tips for tin litho

  • Dust first with a soft brush

  • Clean gently with a barely damp microfiber and mild dish soap. Dry immediately

  • Avoid strong solvents or abrasives which can lift litho inks

  • Treat rust conservatively. Neutralize and seal rather than sand aggressively if preserving patina

  • Lubricate axles sparingly with plastic-safe light oil
