Nor Northern thern Paci acific ic Rail Railway y Dr Drawin wings gs Dean O’Neill September 2018

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

Overview & Drawing Standards

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)

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

Mechanical Department Drawings the good stuff

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

• Issued by Northern Pacific Railway Mechanical Department Standard Drawing for… Sketches • 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

Where Used: Common Examples Mechanical Department Drawings: Sizes • WHERE USED – 1 to X “series” for which the drawing applies • Always in upper right Drawing Details • 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

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

Mechanical Department Drawing: Legend Legend: Common Examples • Title – Always the two lines above NORTHERN PACIFIC RAILWAY CO. • Date – Always the original date, and last revision Drawing Details: Legend • 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

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

Examples – Painting & Stenciling - Stencils

Examples – Painting & Stenciling - Body

Examples – General Plans

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

Equipment Diagrams aka Equipment Diagram Books

• Example here from 1900 (1902 revision), later incarnations no doubt • Issued by “Motive Power Dept.”, later the Mechanical Department Equipment Diagrams: Steam • Data: Road Number, Locomotive Class, Number of Engines, Key Dimensions, Boiler Pressure, Total Heating Surface, Fire Box Dimensions, Tube Data, Loaded Weights, Tender Coal, Tender Water NPRHA Copy

• Issued by Mechanical Department Equipment Diagrams: Diesel • Data: Loco Numbers, Locomotive Class, Number of Locos, Key Dimensions, and a WHOLE lot of operational/equipment data NPRHA Copy

• Issued by Mechanical Department Equipment Diagrams: Freight • Data: Series, Builder, Build Year, Key Dimensions, AAR Designation, weights, and General Plan number NPRHA Copy

• Issued by Mechanical Department Equipment Diagrams: Passenger • Data: Built By, Built Date, Dimensions, Heating/AC, Wheels, Weight, Seating Capacity NPRHA Copy, available for purchase at Store

• Issued by Mechanical Department Equipment Diagrams: Work • Full set of pages on NPRHA web site Equipment • Data: Car Number, Builder, Weight, other NPRHA Copy

• Last updated on April 14 1955, roughly 8 months after the start of NP’s Equipment Diagrams: Transport TOFC operations Equipment • Not updated after that, management decision Richard Yaremko Copy
