Copies of the layout kept in this browser: one every few minutes while you work, and one before New, Open or a recovery replaces it. Put one back to carry on from it; the layout as it is now is kept as a copy first.
Full size, tiled across sheets. Trim each sheet along the dashed seam line, then overlap its neighbour so the registration marks sit on top of each other.
A road drawn the way a gradient is read: its length across at full model size, its height up, exaggerated so a grade can be seen. Its levels, the grades between them and its vertical curves are marked.
Ties, tie plates, rail shoulders and spike heads as one printable strip, following what is drawn. Rails are laid in afterwards. Plates merge where rails crowd together, and nothing is raised in the way of a switch rail.
