Hi Bob,
That tank is indeed an Elesco Feedwater Heater. It used exhaust steam from
the cylinders to preheat the water from the tender before it was pumped into
the boiler. A rather creative way to get a little more work out of the
steam. If you look at the picture of 6313, directly above the 4th driver
and ahead of the air pump, there is the feedwater pump that pumps the water
from the tender, through the heater and into the boiler.
I think that 6319 also has a feedwater heater but if it has one it is
mounted on the left side of the engine and is of the Worthington BL type.
It performed the same function but was of a different design that
incorporated the pump and heater into one unit. I think this is the case as
the air pump has been moved to the right side (the Worthington BL was a
rather large and weighty unit so often the air pumps were relocated to help
balance the engine) and I think I can see the exhaust steam pipes coming
from the front of the cylinders which would carry the exhaust steam to the
heater. However, I may be reading more into the shadows than is actually
there.
Hope this has been helpful,
Bill Allen

Referring to the picture of a CB&Q 2-10-4 #6313 at
http://gelwood.railfan.net/other/cbq/cbq-6313abn.jpg
I have two questions.
1. There is a tank in front of the short exhaust stack that I remember
would usually spout a stream of steam directed into the exhaust. Not all
M4's had the this tank as you can see in #6319 at
http://www.railfan.net/cgi-bin/thumb/abprphoto.cgi?/railpix/ABPR/august01/08-20-01/CBXQ6319SteamatCentraliaILBLXDRColl.jpg
What was the purpose of the tank?
2. What was the meaning of the colored flags up at the top-front of the
engines? I remember seeing white and green. Were there other colors and
what did they mean?
Regards,
Bob
