Loren,
Without getting either too technical or too detailed, the Allied Full
Cushion trucks had certain design and structural shortcomings that could and
often did result in the truck sideframes detaching from the truck journals.
Railroad management frowns on this kind of behavior in a high speed (or low
speed, for that matter) truck.
A second problem was directly related to the first. Preventive maintenance
on these trucks-at least spotting the potential for this problem was
concerned-was nearly impossible without dropping a wheel set.
The trucks were declared forbidden for interchange by the AAR effective
9-1-1959.
Regards,
Dave Lambert

Steve,
I know that the Allied Full Cushion Trucks were banned in interchange, what
was the reason? I know the Q ran them under the Geeps and ran them at high
speed but I've never heard that the Q had problems with the truck. I know
there
is an EJ&E Troop Pullman over at Griffith IN that still has the Allied Full
Cushion Trucks under it, of course it was in company service.
