Yellow Wheel Dot Decals. 1 pair per package

These stencils were applied to designate freight cars which had 33" wheels manufactured by the Southern Wheel Company.  These wheels were suspected of failing in service and causing several serious derailments. This FRA regulation began March 31, 1978 with the inspection of all 70 ton or less cars which had 33" wheels. Freight cars with this type wheels were stenciled with a 6" white dot in a 12" black square. Cars identified with the white dots could not be used in a train carrying hazardous materials. 

Beginning December 31, 1978 cars that had the white dots could not be used in any train.  The wheels had to be removed and replaced with wheels of an approved type.

Freight cars that had approved wheels were stenciled  with a 6"yellow dot in a 12" black square. These cars could be used in any service. New cars built up to Dec 31, 1978 had the yellow dots applied at the factory. There was no date given for removal of these stencils so they remained for several years.
