I recall that the H-9s had unsnubbed trucks, which made them "bouncy."  
I also recall hearing Engineer of Tests Bob Pilcher tell of a derailment 
caused by an H-9 that bounced off the rails at a highway grade crossing 
where the road bed under the track just short of the crossing was 
somewhat softer than the support of the track in the crossing, and the 
weight of the loaded car deflected the track downward at the soft spot 
creating a bump upward when the car entered the crossing.   The springs 
in the unsnubbed H-9 trucks would have been compressed on the bump more 
than those in a snubbed truck and would consequently have had more 
rebound, which apparently was enough to derail it.
