	In later years, much in the way of protocol was
relaxed.     17s and 12s apparently disallowed on 40-line
but Palmer himself approved such usage on NMRA charter  --
in the archives somewhere.     Got the maintenance and
operations people in a tizzy!     Just as a guesstimate,
from 1960 forward operations which had been taboo were
not observed  --  doubt taboo actually changed, it just
wasn't enforced.     And most every rule has its exceptions.
But as we go vurther back in time more definite trends
can be discerned  --  but again, exceptions will exist.


	12s like 17s in that brake shoe was spring applied
and air released.     Also difficulty releasing brakes
for towing and might have been safety issue on grades
on 40-line.

	Agreed.     Drums would be the weak point.

	Assuming the bulk of what you see in European
theater is  All--Electric    ----    seems air-applied
drums are more responsive than spring-applied.

	Only 16s and 17s delivered with drums  --  others
retrofitted.     The 1600s also had extended range dynamics
like 1700s  --  fade at 0.75-mph  --  ALL  16s had this.


	Nevertheless, good grades all over PRCo and PCCs
managed nicely.
