Pullman equipment was operated on the Great Northern beginning in 1922, when GN ceased its own sleeping car operation. The Pullman Heavyweight Sleepers — ‘10-1-2’ (10 Section-1 Drawing Room-2 Compartment Sleepers) are “named” cars and were built specifically for Oriental Limited service in 1923 and lettered for such. In 1929, this ’10-1-2’ was re-lettered for the “EMPIRE BUILDER” with small “PULLMAN” lettering in the upper left and right corners and named “HIDDEN LAKE”.
