General Notes on their Origin

Andreas, A.T. "History of Chicago: From 1857 until the fire of 1871" 1885.

"FRANK M. LUCE, general car accountant of the Chicago & North-Western Railway, is a gentleman whose proficiency in the details of those duties, and ability in their exercise, is not only recognized by the management of the road in his appointment and maintenance in his position, but is also well-known to railroad men throughout the United States. He is the author of Luce's System of Car Accounts, and of Luce's Book of Equipment Lists which are indispensable for car accountants on all the principle lines in the United States and Canada, and which have produced order out of the chaos to which such accounts were heretofore subject. The system was invented by Mr. Luce in 1863, and has grown into such great appreciation that it is now (1884) used by one hundred and eighty-two railroads and fast freight lines, and has received from them the highest eulogiums. He was born in Marion, Plymouth Co., Mass., in 1846, the son of Elisha C. and Lucretia (Clark) Luce. He first entered the railroad business in 1863, as an employee of the Cleveland & Toledo Railroad company, and was speedily made car-mileage clerk, which position he retained until 1866, when he became car accountant of the Toledo, Wabash & Western Railroad. He remained with that road until 1871, when he was made general car accountant for the Chicago & North-Western."

Also note the copied section of the May 11, 1877 "The Railroad Gazette" (unknown page number) (referenced in above groups.io discussion)

Brief Chronology of the Equipment Registers (in general)

(note changes in the columns used are listed in a separate table, see below)
Also note many changes are in the B&M table (below) as I am unsure if the change (and date thereof) were just when the B&M listings changed, or when all railroads' listings changed

Year/Month	Description
1884	There is a much rumored "Trial Edition" published in 1884 Possibly "Luce's System of Car Accounts", and/or "Luce's Book of Equipment Lists" Also see this discussion
1885-06	First published as "Sechrist's Hand-Book and Railway Equipment and Mileage Guide" I have read posts that the first couple (few?) of the first issues did not have "Volume/Number" designations, however, they were "counted" when "Volume/Number" started being used Published monthly from this point until 1932 Note the June issue was "Number 1" for each volume
1887-06	(Vol. III No. 1) Title changed to "The Official Railway Equipment Guide"
between 1896-12 and 1897-03	Title changed to "The Official Railway Equipment Register"
1930-10	(at least on the B&M) Fractions removed from dimension (Inside dimensions rounded down, outside dimensions rounded up)
1932-07	(Vol. XLVII, No. 2) Published Bi-Monthly (every other month) from this point What this means is that there was a "full" register in the July issue (several hundred pages worth). Then every other month until the next July there were "update" issues, only listing the CHANGES from the July issue (indexed on page numbers of the previous July issue) IIRC there is more than one section of "changes" - one for the cars themselves, one for (?)agents, interchange points, etc(?) (and possibly others)
1933-07	(Vol. XLIX No. 1) With this issue, July starts being the "Number 1" issue in each volume
1937-07	(Vol. LIII No. 1) Published quarterly from this point Published July, October, January and April with 2 exceptions that I know of (1973-11 and 1983-05)
1973-11	(Vol. 89 No 2.) Format changes drastically with this issue, so I'm guessing that is why it was "late" Marks the transition from Roman numeral volume numbers, to arabic numbers Also font used for the listings changed from "Serif" ("Roman") style to "sans-serif" ("gothic") style
1983-05	I'm not sure what cause this one to be "late"
ca 1983	Weight capacity changes
1998-01	(Vol. 113 No. 3) pages changed from "just a number" to "prefix + number" - railroad pages are "RR-[number]" (e.g. "RR-47"), and private cars are "PC-[number]" (e.g. "PC-115")
2012	The B&M (my interest) was dropped in 2012, so there may be changes after this date that I am unaware of

Weights

Initially, to standardize (If I understand correctly) the MCB (later ARA, then AAR) developed a standard set of "solid" journal sizes that corresponded to (for a 4 axle car) certain nominal capacities after subtracting the weight of the car itself.

Again, if I understand correctly, these same "nominal" sizes were carried over to roller-bearing equipped axles/journals sizes and capacities.

From 1953-01 ORER (p826), from AAR (MCB) Rule 86
Capacity of car with 4 axles

Axle Letter	Journal Size	Total Weight on Rails	Nominal Capacity (lbs)
A	3¾ x 7	66,000	40,000
B	4¼ x 8	103,000	60,000
C	5 x 9	136,000	80,000
D	5½ x 10	169,000	100,000
E	6 x 11	210,000	140,000
F	6½ x 12	251,000	200,000

Hence this led to "50 ton", "70 Ton", etc. car capacities

Note some cars load limit was not governed by the journals - they would have a star painted next to the Load Limit painted on the car side

[per Tim Gilbert] Prior to 1925 [from when?], the maximum load that could be added to a car was 110% of of the nominal capacity
Starting in 1925, the load limit was calculated for each car, based on that car's weight, and was ["total weight on rails" - "weight of car"] This tended to increase the load that could be carried.

In August 1963 the "Total Weight on rails" (GRL) was changed (increased about 5%)

Circa (when?) the wheel diameters and axle spacing were also standardized for each journal size

Other data related to Journal Size

Axle Letter	GRL	Nominal Capacity	Pre-1925 load limit	Circa 1963 new GRL	Circa 1963 new Nominal Capy	Circa 1995 new GRL	Minimum Wheel Dia	Axle Spacing
A	66,000	40,000	44,000	?	?	?	33"
B	103,000	60,000	66,000	103,000 (no change)	?	?	33"
C	136,000	80,000	88,000	142,000	88,000	?	33"
D	169,000	100,000	110,000	177,000	110,000	?	33"
E	210,000	140,000	154,000	220,000	154,000	?	33"	5' - 8"
F	251,000	200,000	220,000	263,000	200,000	286,000	36"
? (7 x 12)	N/A	N/A	N/A	315,000	250,000	?	38"

Note some cars with clearance issues (auto-racks, depressed center flat cars) might have smaller wheels than called for by the above table

If 6"x11" axles were used with 28" diameter wheels instead of 33", the GRL was reduced to 179,200 lbs. (later increased to 195,000 lbs. with specific 28" wheel designs) to keep wheel stresses within acceptable limits. (Dick Dawson)

7x12 journal size introduced/standardized after 1963

Last B&M Refrigerator cars listed 1951-07 - unknown if there were changes in columns after that. Only data point I have is 1953-01, where PFE listing still has the same columns

Standard Symbols

Note: Initially, I assumed (INCORRECTLY) that the "Addition"/"Increase"/"Reduction" only applied to the numbers of cars.
Later I realized it also applies to the dimensional data
Also note "Reduction" was typically NOT applied for normal "attrition" reductions in car counts, but rather when large numbers of cars were scrapped or converted to another car series.

These symbols first appeared 1918-04 in B&M data

Indication	1918-04 thru 1928-09	1928-10 thru 1952-04	1952-07 thru 1973-07
Addition	★	▲	★
Increase	●	◆	◆
Reduction	▲	[anyone know a Unicode character for this symbol?]

From 1902-04 thru 1909-06 (at least on B&M) "*" (at the end of the "Kind of Cars" column) indicates this series is equipped with Air Brakes

From 1973-11 thru 1981-10: "■" in "Description" column = "series of cars in which exceptions occur"

Starting in 1973-11, they just add a "▸" (although "compressed" left-to-right) to the left of the [car] "Numbers" column to indicate "Change from previous issue"
(Similar to Unicode 🞂 "Black Right-Pointing Isosceles Right Triangle" - which doesn't render in my browser)

In 1992-07, that changed to a
(Similar to Unicode 🠾 "Rightwards compressed arrow" - which doesn't render in my browser)

In "newer" registers (first use on B&M listings ca. 1992-10?) a "J" indicates something to the effect of "the data supplied does not meet UMLER specifications"

At least in my Jan 1953 issue (I don't know how long it was used before/after that date), in the alphabetic lists of private owner reporting marks (at back of issue) they uses a "Maltese Cross" (✠) to indicate that the cars that used that reporting mark are NOT listed in the ORER

B&M ORER Pages Available at the B&MRRHS Archives

Note I list the StJ&LC here (in addition to below), because sometimes it was actually listed inside the other railroad's (e.g. B&L, B&M) listing

Note each PAGE is (typically) a .JPG that is 3-4 MB in size. The original ORER pages indicate how many are available for a giver railroad/date. Be careful what you ask for :-)

• B&M (and predecessor railroads) ORER pages available for 1884 - 1890
• B&M (and predecessor railroads) ORER pages available for 1891 - 2012

Other Railroad ORER Pages Available at Archives

Due to "Collateral Data" (kind-of like collateral damage, only much nicer) sometimes other railroads' data was on the same page (or nearby pages) and occasionally I even captured an image of it ;-)
Note this list does NOT cover predecessor railroads (Fitchburg, etc.) - they are covered above

Where you can find ORERs

If, like me, you want "every" ORER entry for your favorite railroad, here are some places you can start with:

Online (free, no travel required)

• Google Books

  Quite a few before 1918 are available, but they are:

  1. Huge PDFs if you download them (200MB to over 500MB) and I would suggest downloading them for speed)
     But note each PDF has 2 or 3 issues of the register
  2. Scanning quality is a bit "spotty" (some pages are "perfect", some are partly/wholly illegible)
  3. Last "free" issues are 1917, so if you want something later, I don't know how to access them.

  But they are "complete" issues (all railroads, private car lines, index, supplemental pages, etc.)

• Hathi Trust

  I believe one issue is available for "free", others may (or may not) be available if you pay (or access through participating institutions)

Available for purchase

• Westerfield

  Has a bunch covering all railroads:

  1885-06
  1888-08
  1892-08
  1897-08
  1900-06
  1905-06
  1911-12
  1915-01
  1919-10
  1925-05
  1930-12
  1935-07
  1940-01
  1945-01
  1950-07
  1955-01
  1959-01
  1965-01

  
  and for the Penna RR, he has compilations of several years: "1888-1926"; "1927-1950"; and "1951-1968"

• NMRA reprints (1953, 1943)

  These are sold out on the NMRA store, but I believe they can be found on-line

• Original ORERs

  Again, occasionally available at train shows and on-line auctions.

Libraries

• Barriger Collection, St. Louis Mercantile Library (University of Missouri at St. Louis)

  If I had it to do over again, I would have started here. Hotels in the area are not outrageously expensive, and free parking can be had at the hotels and the library.
  There is even a light-rail line with a station stop at the UMSL campus (along old Wabash RR right of way) if you are interested...

  Has almost every register up to and including the "current" one. They are only missing (note I didn't look at everything after 1947, so I am assuming there are no missing registers after that...):

  • 1885 - They are missing "all" (Jun. - Dec.)
    NOTE: there were none published Jan. - May
  • 1897 - They are missing the first half of the year (Jan. - Jun.)
  • 1900 - They are missing "all" (Jan. - Dec.)

  In addition, they are on open stacks (just walk up and get the ones you want) so you can proceed as fast as you want (no "only 10 or 15 items at a time, and we only pull once or twice a day" limits)

• Library of Congress

  Has 1948 - current, all as printed copies. Go to their web site to understand limits (how many they will pull at a time), getting Reader ID card, etc. If you live in DC area and can commute via the Metro / train / bus, probably not a bad option (or get a hotel in walking distance of one of the "far out" metro line stops) When I was there, there were about 30 issues that were just "not available" (they could not give me a reason) Pull requests can (and should) be submitted ahead of time (on the web)

• New York [City] Public Library

  Has 1895-04(?) to at least 2011 (possibly to current issue?)
  1895 thru 1960(?) have been microfilmed, after that they are the original printed copies Go to their web site to understand limits (how many they will pull at a time), getting library card, etc. Note these items are stored off-site, so in my experience getting more than 1 pull a day was hard to do - but note once you pick up the current "pull", you can immediately submit another "pull" request. Also note for the microfilmed issues, there are typically several ORER issues on one roll of microfilm, and each roll counts as one "pull" If you live in NYC area and can commute via train/subway, probably not a bad option, but visiting can be expensive (Hotel + car parking can easily run $250/day) Pull requests can (and should) be submitted ahead of time (on the web) Must(?) be viewed at the "Stephen A. Schwarzman Building" (the "flagship" building at Fifth Avenue and 42nd Street). Although THEY (NYPL) suggested I do an "inter-library loan" (ILL) request to get ones I missed, once I asked the local library to do so, it was "oh, those aren't available for ILL" [grrr....]

• Local libraries in in the nearest "major" city near you

  Buffalo's "main" library had about a dozen, I would assume other large libraries have a few. If they do, see if they will "ILL" them out to a branch near you.

• Universities - Stanford, others

  It looks like most of the Google Books ORERs were in the Stanford library, AND they have all the ones that the Barriger collection is missing.
  (although it looks like Stanford is missing 1917-12 thru 1950-01 !?!?)
  I feel it would be safe to assume some other Colleges and Universities would have a few, if not a lot. I would guess community colleges do not :-) And colleges that were founded after your period of interest probably won't be very helpful ;-)

• Cal State Railroad Museum Library

  Supposedly they have a lot (some from the ex-NMRA library). But every time I emailed them, they have been "less than enthusiastic" about helping me :-(

• Various Railroad related historical societies / archives / museums

  I would guess at least some of them (IRM?, Nat'l Museum of Transport in St. Louis?, Steamtown?, Railroad Museum of Pennsylvania, etc.) have one or more issues in their collections.
