2 Topics Part 1 Part 1 Overview & Drawing Standards Standard Drawings & Sketches Mechanical Department Equipment Diagrams Steam, Diesel, Freight, Passenger, Work Equipment, NPT Part 2 Standard Plan Book Track Standards Signal Department Drawings Bridge Drawings (includes turntables, signal bridges) Specialized Drawing Books Tools Tin ware Lumber for Buildings & Misc. Structures Others? Northern Pacific Railway Drawing Repositories as of 2018 Recent Flurry of Donations Drawing Restoration, Scanning, and Sharing with the World Call to Action the power of shared drawings

3 Overview & Drawing Standards

4 Forming the NPRHA One reason for forming the NPRHA in 1981 was to preserve drawings (which were being tossed, no org for BN to donate to) Large public collection at Minnesota Historical Society, and some at other repositories such as MTM and PNRA Some success, but private collecting became the norm, for better or worse In recent years, some large collections donated (more later)

5 Freight Equipment Drawing Standard Plans - Structure Mechanical Dept - Stencils Car Repairers Tools Mechanical Dept - Painting & Stenciling (10 foot long) Mechanical Dept - Sketch Cornucopia of NP! Mechanical Dept - Z-8 Erecting Elevation

6 Mechanical Department Drawings the good stuff

7 Standard Drawing for Drawings Issued by Northern Pacific Railway Mechanical Department Indicates standard practices and different variances Rick Leach Donation to NPRHA

8 Standard Drawing for Sketches Issued by Northern Pacific Railway Mechanical Department Sketches were the little brothers of Standard Drawings, used for less common equipment or as a precursor to a full Standard Drawing Rick Leach Donation to NPRHA

9 Mechanical Department Drawings: Sizes Where Used: Common Examples Drawing Details WHERE USED 1 to X series for which the drawing applies Always in upper right Most common sizes: Q, R, S, T, W, X, Y, Z. (size of the paper used) Rare: P (sometimes drawings from manufacturers like Alco), V

10 WHERE USED: Some drawings have a HUGE number of series listed for drawing use

11 Mechanical Department Drawing: Legend Legend: Common Examples Drawing Details: Legend Title Always the two lines above NORTHERN PACIFIC RAILWAY CO. Date Always the original date, and last revision Series Always starts with the drawing size (Q, R, X, etc.) Drawing Number, often followed by revision letter Revision Table Succession of letters for each revision to drawing. This is sometimes a list above the legend, no table

12 Other Railroads Of course, other railroads had standard plans/drawings

13 Examples Painting & Stenciling - Stencils

14 Examples Painting & Stenciling - Body

15 Examples General Plans

16 Drawing Titles Common Types First Title Second Title Features General Plans Elevation and Framing Overall or big picture drawing General Plans Arrangement Often shows arranging parts in relation to whole, but also somewhat of a catch-all title Erecting Card 1 Elevation Side view of equipment, usually locomotives Erecting Card 1 Sections 3-7 slice views of large locomotive parts (boilers, etc.) Painting & Stenciling Body Drawing that shows all the stenciling for the piece of equipment Stencil misc Specific letters, or artwork for item like Monad Framing Details misc Shows specific details of equipment construction 1 - NOT a small card. Essentially means Drawing. Could be 10ft long

17 Equipment Diagrams aka Equipment Diagram Books
