I thought they were no longer -required- on house cars but in
fact there are still house cars in service with them... for example
box cars with roof hatches for kaolin service. I think they could
first be omitted about June-July 1966, but I don't have my data
with me.

If the REQUIREMENT was all that was omitted, Tim, why was there an order in force to REMOVE them from older cars when shopped?

I've never heard of a rule banning cars based on location of the brake wheel.

Neither have I, but then again, I don't model the 1960s. If someone knows more about this, please tell us.
