RailMind changelog

What’s new

Every App Store release of RailMind, newest first, in the words a user needs rather than the ones a build log does. The version and build you have installed are in the footer of the Layout sheet.

1.2.0 November 2026

New

  • T-TRAK modules you can snap together. A module is one object: its board and track move, turn in 90° steps and delete together, and snap front main to front main as you drag. A Modules side of the palette lists every module; Edit track opens one up (tap Done to group it again), and Make module groups track on a board back. Save a module to My modules, share it as a file, and open a friend’s.
  • Club Checks list a T-TRAK layout’s open mains, red and yellow swaps, corners that don’t close and the Singles to add, and go green when the loop closes. A module can also meet a layout end red onto yellow when it has to, with a warning and a club check.
  • A T-TRAK module library. 19 ready-made modules built to the NRail T-TRAK standard. Straights (5): Single, Double, Triple, Quad and a Single Concrete Double Track. Corners (6): Outside, Inside, End Cap, Medium, Large and Extra-Large. Crossovers (3): a double crossover and a single crossover in each hand. Sidings & spurs (4): Industry Spur, its mirror image Industry Spur R, Passing Siding and Yard (Quad), three stub tracks off the rear main. Junctions (1): the junction, built from fixed track with no expansion piece. Every one puts the mains on the 33 mm center, 38 mm from the module front, with the rail ends just proud of the board so modules meet. They sit in their own T-TRAK modules shelf of Example layouts. Choose Add to this layout and a module joins the open module edge of your plan front main to front main, its board beside the last one, so a club layout is built module by module in one plan and one Undo takes a module back off. With no open module edge it lands clear alongside, selected, so one drag puts it in place. The board picker gains a T-TRAK group: Single, Double, Triple, Quad, Corner, Inside Corner, End Cap and Junction boards.
  • HO turnouts that match the real pieces. Kato’s HO turnouts now have their real shapes, so Kato’s own HO plans close. The #4 turnout box’s filler pieces (S61L, S61R, R550-15.5 and R550-3.5) are in the palette, and pieces that come in a Kato HO turnout box are counted as “in turnout box” and no longer billed on your shopping list.
  • Sixteen new example layouts, twenty-seven in all — nineteen in N, seven in HO and a T-TRAK club layout. Eight new real-world N plans, four of them with bridges or raised track: Lakeshore Fold, Compact Crossovers, Twin Lobes, Four-Track Stub Yard, Through Yard, Inside Branch, High Line Junction and Trestle Knot. Four of Kato’s own HO plans: Compact No.8, Yard & Siding, Reversing Line and Folded Loop with Two Crossings. A Triple Main plan — three concentric mains, two double crossovers and a #6 siding — and a Desktop Oval. Reverse Loop · Broad R348, a teardrop whose every curve is R348 or wider, so 6-axle locos and long cars run through. And T-TRAK Club · Show Layout: 27 modules on a 17½ × 10½ ft ring of tables, split into two loops by a double-track spine between two junctions.
  • The gallery has a door. An Example layouts button on the Plans sheet, so the examples are always a tap away instead of only on first run.
  • Help, grouped by topic, plus a short Guide of cards under Help and on the Plans screen. Once-only tips point out press and hold and Select.
  • Share a plan. From the Plans sheet, share any plan as a .railmind file or as an image, and open a .railmind you receive straight into RailMind as its own editable plan.
  • A bigger free tier, by scale. 16 straights and curves per plan in N — the M1 starter oval Kato sells — and 20 in HO, where a 22.5°-curve oval takes sixteen curves and two straights. Turnouts and special pieces stay at 2 each; everything else stays unlimited.
  • Zoom out about 5× further, so a whole large layout fits on screen and Fit frames it.
  • Curve chips show radius and angle (R315-15, R348-30), so two curves of the same radius are easy to tell apart.
  • Show menu names in Layout settings puts a short name under each toolbar icon, and Show baseboards hides the boards on the canvas.
  • A new bridge: the Double Girder 186 (20-457), a 186 mm double-track bridge, in the Double Track section of the palette.
  • The print leads back. Page 1 of the 1:1 print carries “Made with RailMind · railmind.grainlabs.io” and an 18 mm QR code to this site, kept clear of the track; the parts list, as text or CSV, ends with the same single line, which you can delete.
  • Rate RailMind. A row in Layout settings that opens the App Store review sheet, and a rating request that appears at most once per version — after an unlock, or after the second loop RailMind closes for you in a plan of your own.

Changed

  • The original Reverse Loop is now marked for small locos. Its R216 curves suit 4-axle locos and short cars; 6-axle locos want Reverse Loop · Broad R348.
  • Ladder Staging leaves the gallery. A plan you already opened from it is your own copy and stays.
  • T-TRAK plans, and HO plans that use the new turnouts, need RailMind 1.2 on every iPad that opens them.

Removed

  • Import from RailModeller. RailModeller 6.7 and later save encrypted .layout files that RailMind can’t read, so the importer could only fail. Paste a parts list still reads a parts list from any planner, RailModeller included.

Fixed

  • iCloud: an edit from another iPad no longer hides the plan or gets overwritten, restoring a backup before iCloud’s first sync no longer replaces newer work, and a new “Untitled” never replaces a restored one.
  • The free-tier counter follows the piece you have selected and counts down; Close loop and Apply say when a route needs more than the free tier and open the unlock instead of doing nothing; the unlock screen names the cap, the route it refused, or the layout that was already over it.
  • Delete is always within reach: a Delete button sits beside Select whenever something is selected. It could vanish from the toolbar in portrait.
  • Deleting a plan asks first. Deleting several at once could remove the wrong one.
  • Every opened example or import gets its own plan id, so two copies no longer collapse into one when iCloud restores them.
  • Dropping an HO piece into an N plan, or the reverse, is refused instead of landing.
  • Taps ignore track on hidden layers, and deleting a group leaves an unrelated build end where it was.
  • The 1:1 print and the inventory CSV import no longer stall the app while they work, and the launch splash is shorter.
  • Layers, paste, Flip, the 1:1 print, Excel CSV export, parts-list paste matching, and many smaller fixes.

1.1.0 August 2026

New

  • Auto-route through turnouts and the wye. The close-the-loop assist threads a route through turnouts and the wye, not just plain track.
  • Grades v2. Smooth multi-piece ramps and an A/B grade tool: pick two points and RailMind sets the grade between them, with the live percentage and the climb shown in the 3D view.
  • Layers. Group pieces onto up to ten named layers you can show, hide and reorder, to keep a large plan manageable. Hiding a layer clears the canvas without touching the parts list or the loop math.
  • “Why it won’t close.” When an open end cannot be closed, RailMind names the reason — the enabled curves cannot make the turn — not just the millimeter gap.
  • Print 1:1. Print a plan at true size to build over, tiled across Letter or A4, with optional piece labels.
  • A new first-run tour built from real screenshots of the editor, the 3D grade view, the parts list and the example gallery.

Fixed

  • Two-finger pan works while you are in multi-select.
  • The appearance switch is a plain sun/moon toggle.
  • Softer splash draw-on, centered piece labels, steadier canvas framing, and dark-mode fixes in the sheets.
  • A less crowded top toolbar; inventory edits are undoable; RailModeller CSV import fixed.
  • The Kato and Unitrack trademark disclaimer now appears in the Layout sheet footer, as it does on the App Store listing.

1.0.0 August 4, 2026

The first public App Store release. What it shipped with:

  • Kato Unitrack in N and HO. Every fixed-length piece in the catalog with its real part number and US MSRP — in N, straights, curves, #4 and #6 turnouts, crossings, the double crossover, bridges, viaducts, bumpers, the double-track system and the electric turntable; in HO, straights, curves, turnouts and the 90° crossing. One scale per plan.
  • Snapping on real Unijoiner geometry, with Close loop and Auto-route to land a joint you cannot, and a clearance check so a plan that closes also fits on the table.
  • Grades and a 3D view — raise a piece, see the percentage, orbit the result.
  • A priced parts list checked against your stock — a Kato or RailModeller CSV, or the Kato set you own — rounded to whole packs, with a parts list from any planner accepted as a paste.
  • RailModeller Pro .layout import, rebuilt as an editable plan.
  • Twelve example layouts, nine in N and three in HO, each with every joint verified.
  • Plans back up to your own iCloud, and the whole library can be exported to a file and restored.
  • Free to build a starter layout — then 10 straights and curves, 2 turnouts and 2 special pieces per plan — with one US$29.99 purchase to unlock every piece, forever.
  • Auto, Light and Dark appearance; a palette that docks left or right; Apple Pencil Pro squeeze for the edit menu; a haptic click when two ends join; undo and redo.
