Simon, Roy, Scott, Bill, Jan,
In researching what information I have at hand, I can pass this info
on to you about the VO-1000.
I was able to gather this info from 3-4 different sources in my
own "library" of CB&Q books I own.
This info comes from:
1. Burlington Route Color Pictorial Vol. 1 by Al Holck
pages 58-59
2. Burlington Route Color Pictorial Vol. 2 by Al Holck
page 22
3. CB&Q in Color Vol. 1 by Mike Spoor
page 17
4. CB&Q in Color Vol. 3 by Mike Spoor
pages 116-117
5. Hub of Burlington Lines West by A. Holck
page 138
Bill is correct about the back-pressure issue and over heating. But
of the 30 VO-1000's owned by the "Q" only 17 were modified to a 4
stack design, and what I read, the modifications were done by the
Burlington. The ATSF also had the same problems and used the
same "fix".
However, the VO-1000's were delivered in two (2) groups. 9350-9357
in October/November of 1943 and 9358-9379 in October/November of
1944. They rode on AAR trucks and had the De LaVergne 4 cycle in-
line 8 cylinder engines.
The books state that most of the 4-stack engines (motors?) were
assigned to the St. Joe Division and worked out of Kansas City
(Murray Yard?).
I went to the Stewart web site and looked up the road numbers that
they did the "Q" engines in, looked through the photos in the above
mentioned books and came up with this:
9353 - 4 Stacks w/radio 6-1961(photo date) Murray Yard. (1.)
9365 - 4 stacks w/radio 10-1960(photo date) St. Joe (1.)
9355 - 4 stacks w/o radio 4-1967(photo date) Valdosta, GA. (2.)
(The numbers in parentheses refer to the book the info comes from,
see beginnig of the post.)
The VO-1000 lasted on the "Q" into the mid 60's when they were
traded in to GE as partial payment for new units (I presume GE
units). 11 of them were sold by GE topower short ACL, becoming SCL
units upon the ACL-SBD merger in 1967 (hense the photo taken in
Valdosta, GA. this photo shows #9355 still in "Q" paint and number).
One last bit of "Q" trivia in regards to the VO-1000's, they were
the only units to have the yellow/red sill stripes reversed from
what the other hood/switcher engines had. On the VO-1000's the
yellow stripe was on top, with the red on the bottom. All the rest
of the hood/switchers were red on top, yellow on the bottom ( and
yes, Stewart did that correctly!).
I also looked at my Bulletins, and there is no Bulletin specifclly
covering the VO-1000. There is one covering the Alco S4 switchers
(diesel).
I hope this helps, and I highly recommend, if you can, to seek out
and purchase the books I mention above, they are EXCELLENT sources
of info and photos of the Burlington Route. The authors (Al and
Mike) put lots of hard work into getting the information they put in
the books as correct as possible!
