Terry, Most US clubs require safety chains on all cars with knuckle
couplers when pulling passengers just in case something lets go. That is
interesting because you almost never hear of a prototype knuckle coupler
coming loose although I can remember the GM&O broke a few of them when
pulling 150 car trains through the Mississippi delta country. That was in
the days before roller bearings on freight cars so they got quite a jolt
when starting off from a standstill especially when going up grade. A lot
of our club passenger/rider cars at Mid-South are articulated with only one
bogie between each car and those are centre seat with solid draw bars.
