[CBQ] San Traps on Budd cars

[Bob Webber <rgz17@comcast.net>]

On Train Orders, there is a thread related to the Sand Traps on the 
Budd-built cars of (approx.) 1952.  The first plan having them that I 
have seen was the BURLINGTON, and they lasted into the CZ SILVER 
LOOKOUT (which had other differences from the original CZ Obs).   The 
FLOWER cars, the 6-5s, 10-6s and such built in this period all have 
the filler hatch on one end (both sides in front of (or read of) the 
truck (toward the end)).

On underfloor/underbody equipment drawings, these are noted as "Sand 
Traps" - the location is at or nearly at where the vacuum attachment 
was located on later cars, and the hatch is located at (or nearly at) 
the location of later lighted number boards.

This was during the flirtation with electric brakes,  and I wonder if 
that had anything to do with it.  This seems like the CZ water tanks 
on the baggage cars, something not normally considered, and rarely 
seen "in action".   GN cars also had these traps.

Anyone have first hand knowledge of these systems and how they were used?
