1. About The PDF Drawings Summary Use these PDF (Portable Document Format) drawings if you want to PRINT the drawings. PDFs generally will print sharper than the JPGs or GIFs that are shown in the previous sections. . . . Pdf Help Which Drawings To Use There are approximately 23 drawings in the Model 1654 4-track PDF directory. The "template" drawing Sheet 39 is the key drawing, followed in importance probably by the "overall wiring diagram" and the "track layout drawing". The other drawings are for additional reference.

Other Comments About The Drawings May 2006 Note - When To Use The Model 402 Template Use the Model 402 template (added May 2006) described in Section C1, if you want to build a 4-track control unit from "scratch", rather than expanding a 2-track unit. The Model 402 Yard uses most of the drawings from the earlier 1654 design (Sections D1 thru D4), but there are 3 new drawings created for the one-piece control unit: Cover Sheet, template, and parts list. Too Many Drawings ?? People sometimes complain that my drawing sets have too many drawings, and they are too confusing. The template drawing is the 'key' drawing. You could just use this drawing, and IGNORE the others. The other drawings are reference drawings - photos, track layout, schematics, initial conditions for operating, parts lists, building dimensions, signal layout. Drawing Confusion ?? These drawings can be somewhat confusing, as they have evolved from one design to another design, and their usage overlaps from one unit to another unit. Assuming you are in the continental United States, the easiest way may be for you to call me on the telephone using the contact link at bottom (or email me a US phone number), and I can call you and give you my opinions, based on what you want to construct.
