Multimark

The Multimark was a logo introduced by Canadian Pacific Railway on June 17, 1968, to identify each of its various operations.

[2] CP Rail had multiple colors beyond its Action Red, which were used across various freight cars to further highlight usage and type: The Multimark was composed three key elements, a circle, a triangle and a square.

[2] The symbol's design enabled it to be adapted to various situations and scales and applied to a wide variety of vehicles across various modes of transport, from railway freight cars, to ship funnels to the sides of aircraft, while still being identifiable as a Multimark.

[2] The Multimark was gradually eliminated in the 1980s as the various components of Canadian Pacific Limited changed names.

While the two companies, other than owning the same ship (RMS Empress of Canada, later Mardi Gras) at different points of the ship's life, are completely unrelated, it has been said that Carnival Cruise Line's logo is a derivative of the Multimark, with the Multimark's edges being rounded out, and the colors changed to red, white and blue.
