Original Feature Request (German):

Ich habe damit begonnen eine relativ große Modellbahnanlage zu planen / bauen (siehe Anlage)
Leider kann ich beim Ausdrucken des Planes keinen Teilbereich auswählen, es wird immer die komplette Zeichnungsfläche dargestellt.
Bei einer Anlage dieser Größe ist es aber meines Erachtens dringend notwendig nur Teilbereiche zu drucken.
Eine Beschränkung auf die nur sichtbaren Ebenen bringt keine Abhilfe da der Zeichnungsbereich ja entsprechend groß ist.
Ist es möglich eine entsprechende Funktion zu entwickeln, wäre sehr hilfreich.

I would like to be able to design new track components and add them to my personal library. The most complicated component would be a switch. I am buliding handlaid narrow gauge track using stub switches. How do I put my designs into my library? Just for off the wall, suppose I had a 4'8.5" inch gauge layout. My switches would all be custom. So it I'm BNSF and wanted to use this software to lay out a new yard, how would I do it?

Like adding tunnels to tracks it would be useful to also add bridges to a track (section)

From our backlog:

Street Elements (dynamic)
- include options for customizing

* center strip (double, color)

* number of lanes

* width of lane

Optionally handle crossings with other roads, heights

In N-scale often an oval helix is ​​used to reduce the rise under 2% because the locomotives are not that strong for long trains. Therefore it would be nice to add a (3rd) oval shape choice to the Smart Insert of an Helix. The Helix Characteristics should be extended with the length of the straight rail between the bends

When designing a custom baseboard it is often difficult to draw perpendicular and parallel lines because you can only select the options length and straight while editing a line. The option to lock the line at 0 ( x-axes) or 90 degrees (y-axis) ( or even at ... degrees ) would make the design of the baseboard much easier and exact.

Center Zoom (alt-mouse function) on Selection.

It is not possible to smoothly change the track gradient. With large inclination angles, it would be good idea to gradually increase or decrease the track angle in the initial (and final) section.

Clearances around track follow specific rules

It would be nice if RM could automatically calculate them and show a shaded area around the tracks. This would help a lot in planning buildings and other structures not to interfere with proper track operation. I think this is an essential part of track planning. Since this can all be mathematically calculated with simple formulas, it should not be so hard.

The ability to to grade Kato N (an HO I am sure) scale double track pieces and super elevated track sections. Not being able to do so is a huge barrier in my design.

Some way that the topography of the baseboard can be changed from just flat so that the user can model hills/cliffs/valleys etc on their layout

Some way of indicating intended direction of travel along a given section of track.

Now we have to switch in and out if the ruler tool. Hard to count grid lines in 1/2" steps or less steps. Just take the ruler measurement from the left side and top and have it follow the item.

We need a library of n scale T-TRAK modules for those of us who are architects of modular layouts at train shows. The "standards" for modules can be found on

Currently when looking at the required parts list for a layout the price of the parts does not take into account the number of that part in a package from the manufacturer. As an example, I require 3 straight sections of track to complete my layout. These sections are sold in packs of 4 at a price of $8.00. If I plug in the $8.00 for the package of 4 (how they are sold) the system will multiply that cost to $24.00 because it thinks each individual track costs $8.00.

I use flex-track to specify curves that ain't available in the (Peco) library. An example is Curve Radius 30 cm and Arc Angle 45 degrees. If i design a 180 degrees curve i need to specify this curve 4 times or use copy paint all the time. I would like to see the possibility to add this curve to the library so the repeat function become available for this curved flex-track.

Please add for base plates :
- copy/paste
- turning
- corner point
- free input of coordinates
- edge :
- direction / angle
- freeze one corner

Group with tracks, allow for copy/paste

Actual railway uses Euler spiral for curves transitions. I would be nice to have an assistant to draw them in RMP : minimum radius setting and a slider to change radius decrease. https://en.wikipedia.org/wiki/Euler_spiral

Sometimes I find tracks on my partlist, which I want to exchange on my layout. But I don't see a possibility to easily find them and get them replaced.

It would be helpful to search for e.g. a certain part number and get these track highlighted on the layout. Maybe with the additional feature to search these certain tracks on the whole layout but also only on certain layers.
