LEGO L-Gauge Railroad Engines & Rolling Stock Build Plans Generator
Create museum-style clone plans for LEGO-compatible locomotives and rolling stock that run on standard LEGO track (L-gauge).
L-Gauge standard: This generator targets standard LEGO train track where the rail spacing is about 37.5 mm
(inside faces). Plans emphasize real-build parts, legal techniques, BrickLink-friendly BOM notes, and reliable running on common radii.
Tip: Some menus allow multiple selections. On desktop, use Ctrl/Cmd-click; on mobile, tap to add and tap again to remove.
Switches the reference set list below.
Locked to L-gauge for this redesign.
All outputs must include this S/M/L label and scale decisions.
If BBB-look is selected, plans must include a LEGO-wheel running option + compatibility notes.
Museum clone plans will be based on the engine style + proportions of the reference.
Pick one car, or select several to generate a matched consist. Any selected items MUST be referenced in the final plans and end prompt.
If filled, the plan text will prioritize “museum clone” accuracy and labeling.
Parts List Filter + Cost Analysis: Paste a text BOM below (any format). This tool will estimate brick count from lines that begin with a quantity (e.g., “12 x …” or “12× …”) and estimate cost at $0.07/brick.
