... the rest of the layout checked for similar misalignments, before you start building track. It would be a shame to construct such flowing trackwork, and then find that by following the templates exactly you have introduced some slight kinks and doglegs. Templot includes all the functions needed to align templates across boundaries, and F7 snapping does it automatically if needed, so it's a bit of a puzzle how these problems have arisen. For example in the loop line (I extended the templates to see the slight kink at the boundary): 2_131502_060000000.png It is not much, but it's at an untransitioned reverse curve and is enough to see rolling stock lurch slightly when running over it, roughly equivalent to the deflection of a C-switch (which would have a speed restriction). With the gauge freedom in 00 it might go unnoticed, but in P4 the wheels track the rails quite closely. And: 2_131505_070000000.png which obviously needs fixing before you print the templates. I haven't checked any other areas for similar problems. Sorry if this is not what you wanted to ...
