The Great Northern bought nearly 20,000 40 foot, DS boxcars starting in 1901. Various versions have been modeled in various media and scales by various companies. Were general arrangement drawings ever published or otherwise available for these cars 'as built' with a wood or steel underframe? I am aware of hand have the Mainline Modeler October 1981 drawing. Something a bit more technically detailed is desired.
