Continental’s Big City HO kits were a short line of vintage injection-molded plastic structure kits for model railroads (HO scale, 1:87), produced in the late 1950s to mid-1960s (references point to around 1964).

They targeted modern “big city” urban scenes with simple snap-together or glue assembly, often marketed as part of a “Modern Architecture Series” (detailed design, easy assembly). The kits came in boxes with instructions and unpainted or pre-colored plastic parts. They are now quite rare and collectible, frequently appearing on resale sites like eBay or Trainz in new/old stock or used condition.
