DETERMINING DRAWING NUMBERS FOR PARTICULAR BALDWIN LOCOMOTIVES:

FOR ENGINES BUILT FROM 1941 THROUGH THE MID-1950s:

The drawings from these years form the bulk of our Mechanical Engineering Drawings series {series #427m.37}, and are the only portion of that collection that are currently processed (in order and easily locatable.) The piece of information that is needed in order to ascertain actual drawing numbers, at least for these drawings produced from 1941 through the mid-1950s, is the sales order number for your locomotive.

1.) If you already know the construction number of a locomotive that was built before 1956 or the name of its purchaser, a search can begin in the Construction Number Books, 1904-1956 {series #427m.14}. The Construction Number Books are arranged by construction number and indexed by name of purchaser, and will reveal the class of the locomotive as well as other relevant information.

2.) Once the class is known, a searcher can proceed to the appropriate Alphabetical Card File of Purchasers of Locomotives {series#427m.1 through #427m.4}, as well as {series #427m.66}, which appears in the list directly above #427m.1. Browse through the entries listed for your purchaser, looking for your construction date (classes are also shown here). One of the data elements listed will be an "order number" or "memo number." This is actually the sales order number.

3.) Another series that might yield your sales order number, especially if the Alphabetical Card Files skip over your year(s) is the Yearly Record of Locomotives Shipped, 1890-1948. {series #427m.67}.

4.) Armed with the sales order number, it is then possible to see if we actually have a Sales Order Book, 1942-1950 {series #427m.51} for that number which includes a List of Drawings. Unfortunately, we probably do not - drawing lists for only seventeen sales order numbers have been found and processed into this series so far (see series description below.)

5.) Most likely, much browsing will be required in the Drawing Directories, [ca.1941-1953] {series #427m.21} looking for that number. The Drawing Directories are not actually arranged by sales order number; rather, they are divided into part categories (elevation, boiler, engine truck, etc.) under which all the drawing numbers and descriptions are listed in chrono/numerical order by sales order number. A searcher will need to scroll down the "S.O." column and look for the desired sales order numbers in each part category to identify the drawing numbers that are pertinent. The Drawing Directories are available for purchase or reader-printer copying on 2 rolls of microfilm should you wish to undertake this time-consuming browsing at home.

6.) The one problem with the browsing method, other than the length of time it can take, is that if your engine used drawings originally created for another, earlier sales order, you won't find those older, reused drawings listed under your sales order number. You will have to use the construction records and indices, or published information you might have access to, to determine what the original locomotives were and what their sales order numbers were, and browse for those too.

7.) Drawing numbers identified can be requested for viewing in the search room, or copies thereof can be requested from afar from the Mechanical Engineering Drawings, Sub-Series II {series #427m.37}.

FOR ENGINES BUILT FROM 1910 - 1940

1.) State Archives staff cannot currently search for drawings for pre-1941 engines, and visiting researchers will find the process time consuming, and with only a small chance of success. The reason for this that drawings are not yet processed (i.e. not in order), and what we have is only a sampling containing mostly small-size drawings for locomotive parts rather than long general arrangements.

2.) The best place to start if you are looking for pre-1941 drawings is the DeGolyer Library at Southern Methodist University in Texas. DeGolyer holds a collection of Baldwin records, including a series of early Mechanical Engineering Drawings, that are processed and searchable.

3.) What the State Archives can help with is this: The specification-type registers contain a wealth of information about the various early locomotives built, and sometimes illustrations or photographs as well. Please read carefully through the series descriptions below to understand the nature of these records and what data they could provide that would be of interest to you. To request a search to be done remotely, you will need to specify which series you would like the search to be done in.

4.) Also, we possess numerous indexes and specifications for early locomotives, as detailed in the series descriptions that appear in alpha-numeric order further down on this page. If you do not know basic information about your locomotive, such as the date built, construction number, engine number or name of purchaser, these indexes might be of help. Here is how the index books can be used to determine drawing numbers:

5.) Once armed with drawing numbers ("card numbers"), on-site visitors to the State Archives search room can then browse through the piles of unprocessed drawings from the Mechanical Engineering Drawings, Sub-Series I, {series #427m.37} looking for identified "card" numbers. Understand that this process may be like looking for a needle in a haystack, and archivists here will not search these drawings for remote patrons until they have been put in order.

6.) A list of local researchers-for-hire, maintained by the Pennsylvania State Library, might be of assistance to those who are unable to visit the State Archives to peruse the unprocessed drawings manually.

FOR ENGINES BUILT BEFORE 1910:

1.) State Archives staff cannot currently search for drawings for pre-1941 engines, including those built before 1910, and visiting researchers will find the process time consuming, and with only a small chance of success. The reason for this that drawings are not yet processed (i.e. not in order), and what we have is only a sampling containing mostly small-size drawings for locomotive parts rather than long general arrangements.

2.) The best place to start if you are looking for pre-1941 drawings is the DeGolyer Library at Southern Methodist University in Texas. DeGolyer holds a collection of Baldwin records, including a series of early Mechanical Engineering Drawings, that are processed and searchable.

3.) If your engine was built prior to 1910, the Pennsylvania State Archives has no indexes that will reveal what its drawing numbers were.

4.) You might still want to utilize the various indexes and registers from your time period to compile incidental information of interest. Please read carefully through the series descriptions below to understand the nature of these records and what data they could provide that would be of interest to you. To request a search to be done remotely, you will need to specify which series you would like the search to be done in.

5.) You are welcome to visit the State Archives search room to browse through the boxes of unprocessed drawings from the Mechanical Engineering Drawings, Sub-Series I, {series #427m.37} looking for images or other notes that might identify which locomotive a particular drawing was for. Such information varies from drawing to drawing. Understand that this process may be like looking for a needle in a haystack, and archivists here will not search these drawings for remote patrons until they have been put in order.

6.) A list of local researchers-for-hire, maintained by the Pennsylvania State Library, might be of assistance to those who are unable to visit the State Archives to peruse the unprocessed drawings manually.

Box and Drawer Listing for Tracings and Blueprints, Compiled by Richard B. Hain, [ca. 1976-1986].
(2 cartons)

microfilmed (2 rolls)

{series #427m.6}

Arranged according to processing inventory numbers, which were assigned randomly in the order in which the materials were removed from their shipping boxes.

Richard B. Hain, a former employee of the PRR, who volunteered at the Archives in his retirement, conducted an inventory of the unprocessed materials in the original shipment from Baldwin-Lima-Hamilton to the Pennsylvania Historical and Museum Commission. Included in this shipment were the various series of indexes that are currently processed, and mechanical engineering drawings of both the pre- and post- 1941 numbering systems. As items were removed from each oversized shipping container, Mr. Hain assigned and affixed a unique inventory number to each item, and typed a brief description of it onto a list. The items were rehoused in a smaller containers able to fit on the Archives shelves. The new containers boxes were given labels reflecting the numbers of the original shipping container from which the contents had been removed, as well as the newly assigned inventory number search drawing or book pulled out and reboxed is given. Many of these boxes have since been sorted through and emptied as the processing of the Baldwin collection has continued. Mr. Hain's inventory continues to serve as a finding aid to the remaining unprocessed boxes. Types of information typically found for each item include the unique inventory number which was affixed onto it, the original storage container number, the intermediate box number, and a description of the item, such as the mechanical engineering drawing number and title block description, or the title and date of the volume.

Card Index to the Baldwin Locomotive Drawings (Fenerty Index),
[ca. 1870-1941].
(30 boxes)

microfilmed (16 rolls)

{series #427m.10}

Arranged alphabetically by part category, and thereunder numerically by drawing ("card") number.

Cross-referenced by Cross Reference Card File to Fenerty Drawing Index {series #427m.17}.

An index to the former location (at the Baldwin facility) of the Baldwin tracings bearing the pre-1941 "card numbers" as unique identifiers. The categories into which the cards are divided are typical of other such indexes in the Baldwin collection, for example - erecting, boilers, cab bracket, flow bowl, etc. Within these categories, the cards themselves take several different forms, the most common showing three columns of information for each drawing, with the category written in at the top or bottom corner. The first column is labeled "check" and contains one of three types of data - a "check" mark, a number, or occasionally nothing at all. The second column is sometimes labeled "drawer" and sometimes "box", and contains what seem to be box numbers. The third column is labeled page and contains a smaller number. A variant type of card is found only occasionally within the "Erection" category. It lists a classification number and the name of the designer for select drawings, as well as dates showing when the blue print was received, when the engine was shipped and when the white print was received. This index does not indicate the current locations of any drawings.

Card Record Books,
1910-1912, 1914-1941.
(11 volumes)

microfilmed (5 rolls)

{series #427m.11}

Arranged randomly by locomotive class, number and road.

Indexed internally by class of locomotive and road, and externally by the General Indexes to Tracings, undated {series #427m34}.

The Card Record Books provide a description and card number (i.e. drawing number) for each locomotive part. If you know the class of a locomotive number and want to know the drawing numbers for each part, this is the series to look at.

For each class, each locomotive number is given its own page. Data shown includes name of purchaser and either drawing numbers or measurements and specifications for each standardized part category. Categories and subcategories for each engine typically include the following.

The card numbers can be used directly to identify drawings, or they can be used to access the Numerical Card File to Drawings, undated {series # 427m.40}, a summary list of drawings. Note that the Pennsylvania State Archives is missing volumes 1 through 28, so it is not possible to use these volumes to identify the drawing numbers for any locomotives manufactured prior to 1910. Note also that the State Archives collection of "card number" drawings is not by any means a complete set. Many drawings are missing.

Change Order Book of C.H. Wheeler Equipment,
1954-1962.
(1 volume)

{series #427m.12}

Arranged chronologically by date of order.

A record of change orders of C.H. Wheeler Equipment. Entries normally list the order number, date entered, customer name, description of change, person assigned to the change, amount of order, and parts data.    A continuation of Change Order data for the years 1962 through 1964 is found in the 1961-1962 volume of the Order Books for C.H. Wheeler Equipment, 1958-1962 {series #427m42}.

Class Books,
1872-1950.
(3 volumes)

{series #427m.13}

Arranged numerically by class of locomotive

Registers of locomotives produced by the Baldwin Locomotive Works. Entries provide numbers assigned to the initial sketches (not at all the same as the final drawing numbers), the serial number of the locomotive, the name of the road or purchaser, the gauge, the type of fuel, date of delivery, drawer number (often blank) and sometimes an additional number in a final, unlabeled column. Unfortunately, the "drawing numbers" and other numbers displayed do not correspond with either the old "card number" system or the three-part drawing numbers of the 1940s and 50s. The Construction Number Books, 1904-1956 {series #427m.14} provide the same information, plus additional data, from 1904 on.

Construction Number Books,

(4 volumes)

microfilmed (3 rolls)

{series #427m.14}

Arranged numerically by construction number.

Indexed alphabetically by name of purchasing railroad, 1909-1930.  Subsequent years unindexed.

A register of engines made by Burham, Williams and Co., 1905-1909, and by Baldwin Locomotive Works, 1909-1956, assigned construction numbers ranging from 24275 through 76151.  Register entries provide the number of the engine as produced within the year; the name of the purchaser; date of the trial; construction number; name or number of engine; engine class; diameter and stroke of cylinders; numerical description of drivers; gauge; type of fuel, flue; and the number of wheels and capacity of the tender.  After 1930, the register shows only name of purchaser, month and year of construction; construction number; name or number of engine; class; gauge; whether steam, electric, gas or diesel electric; and the country for which the locomotive was manufactured. This series is more or less a continuation of the earlier series Registers of Locomotives Ordered for the Years 1854-1907 {series #427m.48}.

Contract Books,
1867-1931.
(4 volumes)

microfilmed (3 rolls)

{series #427m.17}

Arranged alphabetically by part category.

This series is integral to the Card Index to the Baldwin Locomotive Works Drawings (Fenerty Index) {series # 427m.9}. It explains and functions as a thesaurus of engine parts that are not found as (broader) categories in the Index. A typical Cross Reference Card would show an obscure part name, and then the suggestion as to which broader category to check under for drawings of that part..

Cross Reference to the Card Index of the Baldwin Locomotive Drawings,
[ca. 1870-1941.
(2 boxes)

{series #427m.69}

Drawing Directories,
[ca. 1941-1953].
(4 volumes)

microfilmed (2 volumes)

{series #427m.21}

Arranged numerically by part category, and thereunder numerically by drawing numbers, which were assigned chronologically according to date drawing was created..

A categorized listing of all drawings produced by the Baldwin Locomotive Works Company between 1941 and ca. 1953. All drawings listed bear a number in the standard tripartite numbering system of this period - e.g. 12-A-420 or 42-7-2050. For each drawing, information provided includes size (as indicated by middle letter or numeral in the drawing number), subtitle, sales order number of locomotive for which that drawing was first produced (NOT subsequent sales orders reusing the same drawing), date and a person's initials.

This listing, existing in three formats - 2 original volumes, 2 volumes of reduced photocopies thereof, and 2 rolls of microfilm thereof, enables a researcher to browse down the sales order column on the pages devoted to a desired part. If the locomotive in question was the one to warrant creation of that drawing, the sales order number should be found. However, if the locomotive in question reused some drawings originally re-created for another sale order, then the older sales order number will have to be discovered and searched for in order to identify those reused drawings..

Categories into which the drawings are broken down into (according to the first numeral in their drawing number) are as follows:

Standard Practice Book,

(1 volume)

{series #427m.54}

Indexed internally.

As stated in the preface of the volume, it was the intent of this book to record the various rules and regulations which governed the design of steam locomotives by the Baldwin Locomotive Works. These standards were only applied where the customer did not specify otherwise. They were not inflexible and could be deviated from under special conditions and with the approval of the Engineering Department management. As the art of locomotive design was constantly changing with improvements in metallurgy and manufacturing techniques, these standards were continually being revised, and for this reason, were not to be distributed outside of the engineering department. As the BLW Engineering Department was set up under the Group system, these standard practice sheets were numbered in accordance with the groups which handled their design. An attempt was made to keep together all information pertaining to a component, but in some cases this was impossible due to the fact that two groups may design details of a major locomotive assembly. For example, "Front-End Arrangements" were not designed by the Boiler Group and therefore did not appear with the other Boiler details. The Group numbers and categories dealt with in the volume are as follows:

{series #427m.67}

Arranged chronologically by year. From 1936 on, grouped within each year according to locomotive type and whether the purchaser was foreign or domestic. For all years, arranged thereunder numerically by sales order numbers, which were assigned chronologically.

Entries provide the order number or the page of the order book; , From 1906 onward, recapitulations of business by the various agencies generally gives the total amount of sales for the year.

A record of steam locomotives ordered and shipped from the Baldwin Locomotive Works. This series contains several different document types, some handwritten and some typed.. Appearing consistently throughout the date span are charts which generally contains the following information about each sales order or page in the order book: the name of the purchaser, engine class and locomotive number, country where shipped (for exports); the commission percentage; the name of the company, office, district or individual that received the commission; and through whom the order was made. Columns are provided for the following categories, but are not always filled in: superheater, E.T. booster, tender booster, F.W.H & pump, thermic syphons and exh. injector. From 1906 through 1943, additional columns are provided for the following letters of the alphabet, and likewise are not always filled in: C, D, E, F, DD, EE. Early years also provide categories often labeled "Country" or "Commission" which, if anything, usually contain 4 or 5 digit numbers. By 1937, these categories disappear and are sometimes replaced by frame and type. Also shown on the charts are a tabulation of the total stock on hand at the beginning and end of the year, the number ordered and the number shipped. At the top right corner of charts from 1942 through 1948 are found the following three checked-off cross-reference notations: "Card Index, Const. Books, and Terms."

The 1890 and 1938-1939 reports list the purchase price for each locomotive and total amount of sales for the year.

Accompanying the basic charts from 1906 through 1935 are summary sheets showing totals for each district.

From 1919 to 1925, a duplicate record was maintained under the title "Commission Report."

Beginning in 1936, the basic information charts are differentiated into three separate categories. Those entitled "Domestic Steam Locomotives Shipped" and "Foreign Steam, Electric and Internals Combustion Locomotives Shipped" continue to follow the format described above, without the accompanying summary charts.

Another category of chart found, "Domestic Electric and Internal Combustion Locomotives Shipped," adopts a slightly different format, providing sales number, name of purchaser; classification of locomotive; number (of engines of that class purchased?); type of service the engine(s) were designed for (e.g. road freight, road passenger, road passenger and freight, road switcher, transfer or switcher); gauge; three abbreviated categories that were often either left blank or repeated the number of engines purchased - "S.E.", "D.E.", or "G.E."; district and value.
