Leo-
I understand the riding qualities regarding slack action and the advantage of
cushioned underframes.... but did the NE12 and NE13 have much in the way
of cushioned draft gear???
However, the No.7 truck must have given a decent ride as even the
thrifty-minded CB&Q would not have been able to withstand the wheels of progress
and the BRT/UTU for as long as they did. More likely the brotherhoods caved
in because all the other divisions and railroads in the country abandoned
assigned cabooses/waycars. I do know the wood cars were getting pretty ratty
after the BN merger because Joe Legner was approached by the
BN Mechanical Department because they knew we had a full set of waycar drawings
(which they didn't) and they were contemplating a major rebuild of a number of
cars!
Instead, they ended up buying a few of the surplus ATSF cars (redeeming all the
former liars making HO and N Scale copies of those cars painted in any
roadname under the sun!!).
The No. 7 truck must have been a good thing to make a oak, cast iron, and
wrought steel bar assembly design last behind wood burning diamond-stacked
4-4-0s through U33C and SD45 power in a time span of over 100 years!!! The
design shared many details with a number of six wheel trucks and the No.2 (and
variations)
longer wheelbase four wheel passenger car truck.

PS- The UP and the C&NW thought highly of the design as well making almost
identical copies of the No. 7 truck for their waycars... even to the point of
the UP having a
program of reequipping wood and steel cars that had been built with cast
freight car trucks with them...for cars assigned to mainline service!!! They
even officially referred
to it as the "Q" truck.
And talk about a rough ride due to unbuffered slack action !? Must have
been what it was like to ride in the old wooden cars in the 60s. Probably why
they agreed to go to the new pooled cabooses.
