This is like a community garden. It continues to grow with
everyone's help. Thanks for all of the input and your patients as I
juggle multiple projects needing attention. Looking good. Yes...?
I can use a little SQL to get an summary of all the Class found/used
in the roster and in the steam engine photo section. Then we can see
which are found that are not on this chart and classes on this chart
that are not seen in the roaster or in the photos.
Coming in a few months is this (draft) updated photo data page shown
below. It has several new data elements to help members learn/locate
information about stations, fan trips and locomotives. These links
also go the other way. Fan trips to loco photos, roster records to
loco photos, station data to station photos [station data to maps
and geodata]. Linking these various data sets (roster, stations and
photos) helps to straighten and improve the quality of each dataset.

- THANKS for doing this. Taking a
quick look, with the 4-8-4s, there were three
classes: O-5, O-5A and O-5B (oil burners).
The
Class S locomotives were split between Pacific and
Hudson types. Class and sub-class S-1 to S-3 were
Pacifics while Class and sub-class S-4 were Hudsons.
Then,
with the Class L-1 0-10-0s, I don't quite know if
you'd call them "Switcher" as they were designed as
heavy pushers and, later, used as branch line coal
mine locomotives in Wyoming. Hol may have an opinion
on just what to call them.
Otherwise,
looks good to me - Louis

Jack,
I am
no expert by any means but shouldn’t there be an
O-5 Northern in addition to the O-5A?

T.
I love this.
Thanks... all you smart people. The chart now has
S-4B added.

Bill -
You're right, the oil burning 4-6-4s were
indeed Class S-4B. Look at the February
1952 Assignment Sheet on page 293 of the
Corbin Book. Under the Lines West - McCook
Division, the 4002 and 4003 are listed as
Class S-4B with the side notation as oil
burner. So, Jack can add that to his
Classification Chart - Louis

Louis,
You
maybe correct. However, several photos
of 4002 and 4003 show the class
designation in brighter gold than the
rest of the lettering. However, the
photos aren’t clear enough to
determine what is actually shown.
Bill - In a word,
"Brilliant!" One question, I've
never seen an S-4B designation.
Please elaborate where you have -

Jack,
Here are a couple of
comments concerning your
locomotive chart.
1. The H class
2-6-0s should be shown as
“moguls” not switchers as
they were originally
purchased as road
locomotives. Some,
indeed, were used in
switching and branch line
service in later years and
some were converted to
0-6-0 switchers and
reclassified in the G
series.
2. Unfortunately,
over the years, the Q
wasn’t consistent with its
use of sub letter
designation. It most
cases, the sub letter “A”
meant that the locomotive
had been modified from its
as delivered configuration
and upgraded. There were
exceptions, most notable
was the O1A class 2-8-2s.
They were delivered as
O1As from the factory
starting in 1917 and
continuing through 1923.
They carried the “A”
designation as they
included significant
improvements over the 60
O1 2-8-2s delivered
several years earlier.
Over the seven years of
the O1A production run,
further improvements were
made, but with no change
in the sub designation.
The B1 and B1A mountains
were similar. The first
delivery were classed as
B1 while the second group
incorporated some
improvements (most notably
bigger tenders with six
wheel trucks) and were
classified B1A.
3. The Q regularly
upgraded older
locomotives, sometimes
with significant changes,
and would reclassify the
upgraded locomotives. As
an example, many S1 4-6-2s
were upgraded with new
cylinders, valve gear and
other modern appliances
and were reclassified as
S1A. All of the O5 4-8-4s,
S4 4-6-4s and M4 2-10-4s
were upgraded in the
1930s, keeping crews busy
at several shops during
the Depression. The
2-10-4s were actually
changed from their
original heavy coal
service design to high
speed mainline service
between Lincoln, NE and
Denver. They stayed in
that service during WWII
until the FT diesel
locomotives entered
service in 1944.
4. In 1950, the Q
decided to convert some of
their larger steam
locomotives from coal to
oil fuel. This group
included O5As 5614, 5620,
5626, 5627, 5629 and 5632
and S4As 4002 and 4003.
The O5As were reclassified
as 05Bs and the S4As were
reclassified S4Bs. All
were assigned to Lines
West, Lincoln to Denver.
The Q had many other
locomotives that burned
oil, but none of them
carried the “B”
designation. I don’t know
why. As an example, all 15
O4 2-8-2s were converted
to oil in the 1920s, but
never received the “B”
designation.
I hope this gives
you a little insight.
Hello all:
While working on improving
the BRHS web site's steam
locomotives photos and
roster data I put together
this chart.
It can be found on the
BRHS web site at this URL.
Note that it is in the
Members Only area so you
will need to log on before
using this link. https://www.burlingtonroute.org/members_only/secured/steam_roster/steam_locomotive_classifications.php
If you folks who are
experts in the steam
locomotive (not me) see
any errors in this chart,
please reply. Also if you
know the meaning of the
different class numbersand trailing letters,
please send me that and I
will add that to this
chart.
<zOfELp1o7cThUefw.png>
If you visit the BRHS
photo feature and browse
the steam locomotives you
will see that the titles
below the photos are
undergoing a change. They
are all being changed to
the syntax seen
in the example below.
Location and dates are
added were available. The
location and dates are not
included for search
results at this time, but
are included for Category
and Album browsing when
choosing steam
locomotives. Cool... Yes?
<YBqpEVNxwcXFz9fT.png>
BTW, the comma after the
engine number is very
important as it allows for
the reading of this title
with a program that will
enable connecting the
roster data to these
photos. In other words, please don't edit them out.
Thanks! If you visit a
steam locomotive page that
has not yet be revised to
this syntax, I invite you
to edit this title change.
Don't forget the comma.
