Long
modelrailsim.com is a model railroad simulator and track planner that runs in a browser on a computer, tablet or phone, with nothing to install. In the Layout Designer you lay real pieces, by hand or by describing the layout to the Planner, from 39 track systems by 18 makers in eight scales from T to G, each with its real geometry and part numbers. The Designer checks gaps, grades, clearances and wiring, places feeders, insulated joiners and auto-reversers, draws the benchwork and the DCC hardware under the board, and can put a photo of your room under the plan with the aisles checked. The parts list prices the layout at real stores, with live stock where a store is connected, and prints the plan 1:1, tiled, to lay track on. Save, and the design opens in the simulator wired and ready to drive, in 2D or 3D, from a cab modeled key for key on the NCE Power Cab or the Digitrax DT602, with real recorded sound. Two classic switching puzzles, the Inglenook and the Timesaver, are scored on moves and time against the fewest possible, with a leaderboard. The app is free with no time limit; the AI helpers use AI Credit, with the first $5 on the house and packs from $5. modelrailsim.com is made by Iron Rod Systems LLC, founded in April 2025 in Salt Lake City, Utah, by Jeff Hunt.
