The previous Section D2 shows you just the KEY drawings. The next Section D4 shows you all the "operating" drawings, plus some other reference drawings. Building In Phases The track unit drawings (Sheets 33, 34, & 35) and tracking wiring drawings (Sheets 36, 37, & 38) show 3 "phases" of construction, single-track, double-track, and 4-track. This allows you to build the system in progressive steps, starting with just 1 track, then progress to 2 tracks, then progress to 4 tracks. Other Comments The first drawing, Sheet 31, lists these drawings by number. You use the #1651 Main Control (Sheet 09, part of Drawing Set Item 4) from the Two-Track Block Drawings, as the Main Control Unit for the 4-track Zellner Yard. 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.
