The "mine tailing" guess could be accurate. It seems the 4000 cu ft cars
survived in hazardous waste service a long time . Most of these cars went on
to the BN , and got painted into all three of their freight schemes . There
is a picture of BN 450063 in
Dave Casdorph's BN Freight Cars Illustrated - it is in the last BN scheme - and
it is so
corroded from whatever it has been hauling that the lettering is almost gone.
Mine tailings would be full of acid fumes. If you have ever opened a bottle of
concentrated sulphuric acid , you know how these fumes spred and flow down to
the ground. The car in the picture is going thru Nampa , Idaho in 2001.

I have a question that's been nagging me about the CB&Q's covered hoppers in
the 85500-85639 series. I've found a couple records of these cars used to haul
"SLUDGE" in 1969, but do not know the origin of the loads. The loaded cars came
north to Laurel, MT, interchanged to the NP and thence west to Tacoma, WA (I do
not have exact destined receiver information). Anyone know what exactly these
cars were hauling, and better, what their weathering looked like in this
service? It's most likely the loads originated from an on-line customer on the
Q or C&S, but also possible the cars were assigned to a pool for a shipper off
of CB&Q rails.
Pure speculation, but I've wondered if this might possibly be mining waste of
some kind sent to ASARCO's Tacoma smelter for reprocessing.
