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.

The name

Write it as one word

modelrailsim, lowercase, even at the start of a sentence. With the domain, modelrailsim.com. Not Model Rail Sim, not ModelRailSim, not MRS in text (the plate on the locomotive is the only place MRS appears).

Tagline: Model railroad simulator. Headline: Plan it. Price it. Buy it. Run it.

The AI helpers have names: the Planner in the Layout Designer and the Conductor in the simulator. Call it a simulator, not a game.

The lockup

The mark beside the name in Inter 800, with "rail" in orange and the tagline beneath. This is how it appears at the top of every page.

Logos

Two drawings of the same locomotive. The vector mark is the everyday logo: it is what the site uses, and it stays sharp at any size. The illustrated mark is the full drawing, for print, merchandise and anywhere it can be shown large.

Vector mark

Use this one. Headers, icons, avatars, slides, anything on a screen, and print at any size. The ring and the track are ink on light backgrounds and white on dark: pick the file for your background.

SVG, for light SVG, for dark SVG, follows the theme PNG, for light PNG, for dark On cream On dark

Illustrated mark

The full drawing: rivets, the MRS plate, the peaks as a line drawing. For print and large placements, 200 px and up. Transparent background.

PNG 883 PNG 512

Illustrated mark with the name

The same drawing with the name arched over it. Black lettering for light backgrounds, white for dark. For posters, banners and shirts where the mark stands alone.

Black lettering White lettering

Original illustration, for merchandise

The first drawing, with the mountains shaded. This is the one for T-shirts, mugs and other printed goods, on white or light fabric. White background, not transparent.

Mark With the name

Do

Keep clear space around the mark of at least a quarter of its width.
Show the vector mark no smaller than 24 px, the illustrated mark no smaller than 200 px.
Use it on cream, white, the dark page color or a photograph with room around it.
Set the name in your own type if you need to; the mark alone is enough.

Don't

Recolor, outline, rotate, stretch or add effects to the mark.
Put it in a different shape, or crop the locomotive out of the circle.
Pair it with another logo so it reads as one mark, or imply an endorsement.
Use the old orange badge; it was retired in October 2026.

Colors

The founder

Jeff Hunt is the founder and CEO of Iron Rod Systems LLC, the Salt Lake City company behind modelrailsim.com. A modeler himself, he built modelrailsim so that the track geometry, the capacities, the rules and the throttle match the real thing, and so a layout can be designed, priced and run before a single piece of track is bought. He is available for interviews, demos and podcasts: press@modelrailsim.com.
