First Steps

The following images show:

  1. Original image as scanned from Stindt's book "The Northwestern Pacific Railroad, Vol 1" (c. 5700x1500 pixels).
  2. Reference image from which the major measurements for the general view drawing was defined. From the previous image that has been perspective corrected and filtered (to reduce the print screening) using PhotoShop. Note that the correction holds good only for the vertical plane at the wheels.
  3. General View drawing - October 2000, (with some "place holders" e.g. tender trucks).
    Notes: 1 - Headlamp and other details are as per working NWP locomotive (see Stindt) rather than ALCO's configuration. 2 - This drawing was made before I obtained the general arrangement drawings and builder's information.
  4. General View drawing - Updated February 2002.

Please Note: The above images are 900 pixels wide as below this resolution the line drawing details become unreadable.
