What this mark means

SP does not end in X, U, or Z. Those suffixes are the AAR conventions for private railcars, containers, and trailers. A mark with this shape is the kind assigned to a railroad or other common carrier.

The owner wording comes from the English Wikipedia reporting-mark list, with wiki markup removed. An arrow (→) is a succession of names as that page printed it. A semicolon separates more than one company listed for the same mark. RailcarID does not decide which name is the current one, and it does not attach a build date, a dimension, or a location to any individual car.

RailcarID does not show where this car is, and it does not republish equipment-register details such as a build date, a dimension, or a pool assignment for car SP 9600. The number is the one you looked up. The owner line, when there is one, is the reporting mark's Wikipedia entry.
