Hi, Milen,
Congratulations on the release of SCARM v 1.9.4.
I have verified that the included japanization file has been updated to the latest version. Thank you very much.
Thank you, Takashi
Hi Milen, writting from Mexico City. Quick question, I created 3 layouts on a previous PC, but my new employer will not allow SCARM to be installed in the new computer. Though I have the files, I’d like to know if there is web viewer? I don’t want to edit the files, just see them and even print them if possible. Is there a way to do this? thank you so much. The app is great!
Hello Daniel,
Unfortunately, there is no web-based viewer for SCARM project files.
Note that there is no need for license key, as the free version of SCARM can open, view and print every project, even bigger ones, created in the paid version. However, you need a PC where SCARM can be installed in order to view the SCARM project files.
Hi again, thank you for your prompt reply. I need to get a PC then. That should solve the issue, don’t worry. My projects are saved already. Appreciate the response though.
How do you create custom track libraries? It may sound silly, but I’d like to use SCARM to create interesting layouts for some of the simple plastic and wooden track systems that exist (for example, those associated with Thomas the Train). I would be happy to input all the track geometries myself. It seems like this is something that’s relatively easy to do with XTrkCAD (insofar as anything is easy with that software!), but here the SCARM libraries don’t seem like they can be edited and I’m not sure how to create custom track segments.
Hello Zachary,
Currently, there is no such option in SCARM, but I am working over custom tracks editor and it will appear in some of the next versions of the program.
Regarding Zachary Bond’s recent question, I want to suggest there is a work-around for creating a ‘custom’ track library. I’ve sometimes done this myself to represent GeoTrax and other unique types of track.
Using flex-track that best approximates the size of ‘track’ you want to represent, make straight and curved ‘sectional’ pieces of track with the geometry parameters of your choice. Copy a number of these pieces into a separate layer and off to the side of your layout planning area in a SCARM file. Save this file as a ‘library’ with your ‘starter’ pieces of track.
Turnouts and crossings can be represented with overlapping straight and/or curved sections. Ramp sections can be created by specifying graduated heights on a track section, but beware when joining adjacent sections to maintain correct heights.
When you create a layout using track sections in this file of custom pieces, save any new layout creation as a separate file. Retain the original unmodified file as your ‘library’ of custom sectional pieces.
Hope you find this method useful.
Best Regards to Mixy for creating SCARM. The software is very useful, versatile, creative and fun to use!
Just wanted to express my satisfaction with SCARM.
Easy to use, even fun to use a lot of times, and client support is amazing.
Eternally thankful and greatly appreciative of how easily I can set grade percentages with SCARM – it’s all automatically calculated (riser height and grade percentage).
The low price of the license for the unrestricted program is the best money I’ve spent for a long, long time!!
EXCELLENT PROGRAM, MILEN!!!! Thank you
Thank you, Art,
I am always glad to read comments from satisfied users of SCARM
Please give us a setting to specify screen size and position on open or any thing so you can recover from a Microsoft forced shutdown when SCARM is not full screen on a multi screen setup.
I had multiple SCARM layouts open so I do not know which whido closed last but needed to reconfigure and disable all but one screen to be able to get back into SCARM becasue no edge was visable on open, not the bigest thing but this causes me to lose all ICON locations on my home screen overall almost a hour to get SCRAM and home screen running again,
By the way have tried all the other layout software and this is still the best cant wait for next major upgrade that will include customizable track sections (Hint Hint)
Hello Jim,
OK, I will consider how to make the recover from such unexpected fails easier on multi-monitor systems for the next versions of SCARM.
Hi Milen. Been using your software to help fellow Lionel Super O track members on Group. iOS platform. Is it true they may view my large files of a layout in the free version?
Another question, I have “built’ some Lionel postwar accessories by using your figures library. Is there a way to share them here with others.
Last question, does your program work with Windows 11? Micro Soft keeps wanting me to do an update to it.
Thank you and I’m looking forward to your new version which may image Super O track in 3D correctly.
Best regards Rob W.
Moderator of Super O Track group.
Hello Rob,
1) Yes, that is true – the free version of SCARM can open, view and even print any track plan, created with the paid version. However, if the plan is bigger than 100 tracks/objects, it cannot be edited or saved in the free version.
2) Sure, you can do that – just share the file where these figures exist with your friends and they will be able to copy them and paste onto their own SCARM layouts and track plans.
3) Yes, SCARM works just fine on Windows 11.
Hi Milen. I was having issues with printing and contacted Parallels for help. They said my problem was with Windows 7 and I needed to upgrade to Windows11. That apparently fixed the printing problem, but I had to reload SCARM. I purchased the Power Edition many years ago, but I don’t have a license key to reload it. Please tell how to do that.
Best regards,
Dave
Hello Dave,
I received your inquiry by e-mail and will reply there.
Hi. I’m new to computer aided design for model trains. I want to design a layout for my shed. I have all Kato unitrack track etc. How to I start off using Scarm.I am computer illiterate. I am 74 and never learnt!
Hello Sydney,
If you are new to SCARM, please, start by watching all the video tutorials here: http://www.scarm.info/blog/tag/lesson/?order=asc
Then you will be able to plan your first layout with SCARM.
Thank you Milen. I’ll give it a go.

How can I reinstall all track libraries? When I did the initial install I only installed HO libraries and now I need have also 00 and N. I tried to reinstall the program but allways show the initial libraries downloaded.
Thks
Hello Arturo,

All track libraries are always installed, however, some may got switched off by the user from the settings. In order to get back all installed libraries, go to “Tools” > “Settings” > “Tracks Panel” and place a check marks on all required scales in “Selected scales” list:
Great program. Only problem is I bought it in 2018 and my laptop that I installed it on , gave up on me , so the program became obsolete .
Hello Leon,
and request emergency license reset, stating the purchase Ref No of your license(s) and I will then unlock it in 1-2 business days.
In such case, please, write to
Note: Emergency license reset can be performed only once per year.
Having great difficulty trying to do anything with V1.9.5. Have created plans but all it wants to do now is update to V2 which I do not want/need. Similarly cannot swap files with a friend in 1.9.5. Its getting very tedious!.
Hello Michael,
This version is obsolete and not supported anymore. However, if you want to continue to use it, you can do that, but only in registered mode (with a license key). So check that you have a license and that it is installed and recognized. To do that, start SCARM and open “Help” > “About” menu command – you should see your name at the bottom of the About dialog. If you do not see it, then SCARM is working in Demo mode and that’s why it wants to be upgraded. To fix this, use “Help” > “License actication and installation” in order to login into your account and download and reinstall your license key. More details about this process can be found here: https://www.scarm.info/index.php?page=webshop&item=scarm_license_key&step=guide
