	PRCo 1600s had  Air--Drums  --  only PRCo air cars
built with drums.     This is a technical note made to
dispel the possible assumption from above that these were
wheel-tread brake shoes!

	All other PRCo Air-Cars built and delivered with
Wheel-Tread Brake Shoes  --  some in each series from
1200s forward converted to drums.

	The 1200s always made operators nervous because
these beasts had a tendency to roll backward when stopping
uphill  --  spring applied wheel treads or spring applied
drums If converted to drums.     Interesting that it was
under the 1200s where the Experimental__B3s were tested
And All B3 trucks were All-Electric with spring-applied
drums    ----    Except the PRCo 1600s converted to
interurban service  --  air applied drums!

	And the 1600-series interurbans with B3s didn't seem
like they would stop even going forward on the level  --
strictly perception as a passenger.     Maybe they would
be excellent on Fineview - take foot off power and the car
would stop because it is uphill.
