CB&Q minions, all; Lube oil, air compressor oil and cooling water samples were
taken at regular intervals to help determine if the fluids were contaminated or
were beginning to break being past their useable service life. These samples
were sent to various shops that had the facilitities and equipment to perform
these specialized tests. Many will remember the square white boxes contaning
plastic jars with black lids containing those samples. Preprinted labels were
supposed to be used on the jars one can only imagine how the brass thought a
pen or pencil would make legible entries on the oil and water soaked/stained
labels. What was usually done was to scratch the number of the sampled unit
onto the painted cap of the jar with a screwdriver, key, or nail, although on
occasion, a churchkey, when not in use elsewhere might be pressed into service.
When a sample showed that something serious such as lead, babbit, copper,
cooling water anti-oxident might be present in the sample, the unit was
immediately shut down and drained and put dead-in-train so it could be sent to
the next maintenance facility where the crankcase, oil cooler, or compressor
could be inspected. This was another reason for switchers and other units seen
enroute dead in train. Best Regards, Bob Munshower
