What is the difference between RailModeller and RailModeller Pro/RailModeller Express?

We currently offer three different apps for planning model trains on the desktop for OS X:

  • RailModeller (also known as RailModeller Classic)
    Our legacy app sold until 2014 was originally designed for Classic Mac OS (OS 9) and later ported to OS X. It was only available directly from us at our online shop at KAGI.
    The app is still available for download but has entered maintenance mode and will receive no further significant updates extending the functionality of the app.

  • RailModeller Pro
    Our current app introduced in 2015 and available exclusively on the Mac App Store. It was recreated from the ground up to take advantages of many modern features offered by OS X.
    As outlined in our road map the app is under heavy development with new features being added constantly.

  • RailModeller Express
    The free edition offering features similar to our Pro edition for small layouts was introduced in late 2015 and is also available exclusively from the Mac App Store.
    A comparison of the Pro and Express edition can be found here.
What is the required macOS / OS X version?
RailModeller Pro and RailModeller Express require at least Mac OS X 10.9 Mavericks or newer.

Our legacy app RailModeller Classic (Version 4.1) supports Mac OS X 10.4 - 10.11.

Can I use RailModeller Pro on more than one computer?
Yes: Apps from the Mac App Store may be used on any Macs that you own or control for your personal use.
You can simply install RailModeller Pro again from the Purchased tab in the App Store app:
I've bought RailModeller Pro before. How do I install it on my new Mac?
Since you've purchased our app from the Mac App Store you can (re-) download it at no additional cost to any of your Macs as often as you wish.
Simply open the Purchased tab in the App Store app, browse for RailModeller Pro and click on the Install button:
Are updates free?

Updates to RailModeller Pro are made available automatically through the Mac App Store update mechanism.

All updates to the app are made available for free - in fact, we're just getting started: We've got a long list of great features to be added over the coming months. We're updating the app at least once a month so you'll see new features pop up frequently. Make sure you'll also check our Twitter feed or the news section for related updates.

Do you offer a free trial version?

We are offering RailModeller Express, a free solution for planning small model railroad and slot car layouts on the Mac App Store.

You can find details about the Express Edition on our product page.

Do you support my track system?

Please check our up-to-date list of supported track systems!

Why are tracks from vendor XYZ not included?

New libraries are constantly added to RailModeller Pro.
There are few vendors which - for a number of reasons - don't provide detailed specifications of their tracks. Without this information it is often not possible to create these particular libraries.

Having e.g. only photographs of the tracks doesn't allow us to create a library for a track system.

If you have any detailed information about a track system not yet included in the RailModeller distribution, please feel free to send them to us and we're happy to update our libraries!

How can I create an L-shaped layout?

The File > Add Baseboard function can be used to add baseboards defining a layout's dimensions that can even include measurements for individual baseboard borders.

The Baseboard Assistant provides templates for a number of commonly used layout shapes - like L-, U- or rectangle shapes - that can be modified for any particular layout with a few clicks.

Once added to a layout the baseboards are organized in a dedicated layer so they can't interfere with your planning when working on a layer with tracks. Baseboards can also be filled using any desired color - without even covering the grid.

Can I add images?

You can add images to the layout by either simply dragging the image file on your layout opened in the app or by going to the File menu and choosing the Add Image command.

Is it possible to change the unit of measurement?

Multiple units of measurement are supported: millimetre, metre, centimetre, inch, foot, yard.

The current unit of measurement can be selected in the app's preferences.

Bring to Front/Send to Back doesn't seem to work!

The "Bring to Front" and "Send to Back" commands don't seem to work.

The order in which elements are painted is controlled by

  1. The order of a layer in the Layer List:
    layers at the top of the list draw above layers at the bottom.

  2. The order of elements within a layer:
    Within a layer the "Bring to front" and "Send to Back" command can be used to control the back-to-front-ordering of elements within the layer. Elements in different layers are however drawn in layer order.

This is similar to most modern graphic applications, however it's different from how RailModeller Classic (Version up to and including 4.x) worked.

How can I adjust heights or create a grade?

Please note that adjusting height is currently supported for track elements only.

There are several ways to adjust track heights or create grades:

To create a grade to a specific track

  • Select the track in question, then
  • click on the height/grade field in the sidebar to the right or
  • use the "Element > Adjust Height" menu
  • in the Dialog enter a target height and adjust settings accordingly.

To adjust start and end height for a range of track

  • Select a range of connected track elements, then
  • click on the height/grade field in the sidebar to the right or
  • use the "Element > Adjust Height" menu
  • in the Dialog edit the heights at the start and end track.

You can also reset the heights and grades for all selected elements using "Elements > Adjust Height > Reset...".

You might want to make sure the track height profile in the lower third of the document window is active by using the "Layout" control in the toolbar to get live previews when adjusting parameters in the grade and height dialogs.

Is it possible to import Stock from RailModeller Classic?

The Stock Management module in RailModeller Pro features a CSV Import/Export functionality.

In order to import your stock from RailModeller Classic (Version 1-4) you can simply export it as a CSV file in the old app and import the CSV in RailModeller Pro.

Can I view the layout in 3D?

You can use the Layout control in the toolbar to switch between a top view from above (2D), a combined top and side view (2.5D) and a three-dimensional view of tracks in your layout.

As we're aiming to enhance the 3D planning capabilities with full terrain modeling as well as 3D structures placed at arbitrary heights a much enhanced three-dimensional viewing mode will follow in a few months.

Can I edit track libraries myself?

The current release of RailModeller Pro does not yet feature an editor for libraries.

We will add a dedicated editor module in an upcoming release!

Can you please add (...) ?

We are running a feature request forum at UserVoice that provides a great platform for our users to suggest new features and vote for feature requests by other users of the app.

It also allows us to prioritize items on our road map to make sure popular requests will be added as soon as possible. We're publishing a list of all feature requests that have been delivered in a particular release on our Twitter stream as part of our release process!

I can't find the scroll bars!

In new versions of OS X the scrollbars are hidden until activated by use - i.e. scrolling - making them invisible by default.

You can always change the system setting in OS X if you prefer the old behaviour:
