Re: Duryea Underframes

The 1970 Field Manual of the AAR Interchange Rules tells us under rule
90, 3b that cars equipped with Duryea underframes are prohibited in
interchange effective July 1, 1972.

The 1978 Field Manual tells us under rule 90, 3b that cars built prior to
April 1, 1950 equipped with Duryea underframes are prohibited in
interchange.

Something changed in those eight years. I've exhausted my post 1970
sources but it appears that Duryea underframes could be seen after 1978.
Someone with a more comprehensive library could tell us

Later,
