Most N-scale layouts start with cork roadbed and hand-pinned flex. This one turns that sequence on its head: the complete track layout is printed as modular ballasted sections, the flex is laid in, and DCC-EX runs the trains rather than a mainstream command setup.
The plan has real ambition for the footprint. A table-level section sits alongside an elevated loop carried on pillars as a flyover, all resting on a foam insulation base over a wooden workspace. The Santa Fe lettering on the diesel and a tower with a rooftop helipad give the printed city some character.
The standout is the software viewer running beside the physical layout. It mirrors the track plan down to the loops, the viaduct, the supports and even the crossover, and shows parts, assembly steps and print plates while animated trains pull a boxcar, a tank car and a hopper. A digital mirror that doubles as a build guide seems a clever use of the printing workflow, and with two DCC trains running at once on the real layout, the maker counts this as a big milestone, which is easy to agree with.
Plenty is still open, and the maker is upfront about it: a third train waits until sensors and signalling arrive, an ESP32 control panel with throttles and signal and sensor controls is planned, and building lighting plus grass and terrain work are on the list. Printing stood at roughly 30 percent at the last update, and the run from there to a fully laid, two-train layout has been quick. I am curious whether the buildings still to be generated with Astra will sit comfortably next to the printed ones already in place.
