Everything About The Transition to SCARM 1.0 Milestone

Some of you probably already know, that I released the SCARM v. 1.0 Milestone version in the end of July 2017. Many users were happy to get the new version, but some were not, because there are changes in the licensing model and not all were aware of that.

I am writing this post in order to try answering of all questions about the transition to the new version and to clarify the new way that I am taking with the development of SCARM for those who do not follow the posts in my blog.

March 2017

A half year ago, in the beginning of March 2017, I stated that SCARM 0.9.35 (RC1) will be one of the last beta versions of the program in the post SCARM v. 0.9.35 Released. At this time, I was already not sure if I will be able to continue to develop and share SCARM for free. The truth is that I was believing that more model train fans will support my work and will either donate or buy licenses for the MTS Power Edition. But I was wrong.

July 2017

In the months from March to July, after I saw that there are no increase in the donations (1-2 per month) and that just a few people are willing to pay for the MTS PE, I decided that SCARM should be turned into partially commercial project. So, in the beginning of July 2017, I announced the upcoming change in the post SCARM Approaches v.1.0 Milestone and explained why I need to do that.

In the end of July, I was ready with the first complete production release of SCARM and it was officially published. All details about it are described in the corresponding blog post SCARM v. 1.0 Milestone Released.

August 2017

The releasing of SCARM 1.0 Milestone edition makes the previous beta versions of the program obsolete, so I announced the Phasing Out of The Old Beta Versions of SCARM. All 0.9.x versions will stop to work at some time (not all together) or will become unusable for creating of new layouts and I do not intend to prolong their lifecycle. But don’t worry, your project files are not lost at all. You can always open, review and print all layouts, created in the old beta versions by use of SCARM v.1.0 and that does not require pur­chas­ing of license key. However, if your track plan contains more than 100 tracks/objects in it and you wish to continue to edit and save it, you will need to get a license key for the new version. If you already donated or bought license for MTS PE, see how to obtain a free SCARM License Key below.

Now and the future

I am very thankful to all of you, who are using my software and especially to these, who helped me with information, catalogs, ideas, tests, corrections, translations and thoughts about my work. A special thanks to all, who shared their track plans and custom virtual objects designed in SCARM with all other users and fans of the program. And one more big THANK YOU to all, who have made donations to the SCARM project or have already purchased license for MTS Power Edition.

For all those, who already donated to SCARM project, bought MTS PE licenses and/or contributed with content and translations to the development of the program before the releasing of v. 1.0.0, I am offering free or discounted license keys for the new version as follows:

• All Model Trains Simulator – Power Edition users are receiving FREE License Key for SCARM v.1.0 Milestone edition. The license keys are already uploaded and activated in your accounts.

• All users who donated to SCARM project will receive FREE License Key for SCARM v.1.0 Milestone edition. Just send me a letter by e-mail to and state the account (Paypal e-mail) from which you made the donation.

• All users who contributed to SCARM either with track systems info or major translations of the user interface and the documentation, will get a promo code for discount in order to purchase License Key for SCARM v.1.0 Milestone edition on a reduced price. Just send me a letter by e-mail to and remember me when and how did you contributed for SCARM and I will then issue your promo code.

I assume, that some of you may be not happy or even frustrated that I am turning SCARM into partially commercial project, but that is the only way for me to continue to develop the program and to ensure the quality of the product and its support. I was working over the SCARM project and sharing it for free in the past 7 years and even now, it continues to be free for small and simple projects. But if you want to design bigger and/or complex layout with SCARM, please, support my work and pay the license fee – it is no more than the cost of one or two real turnouts in your preferred track system.

Thank you for your understanding.

  1. I have been working with SCARM for over a year now and am very impressed with all that it is able to do. I would have paid for a license sooner if I had known about it. I will happily pay now. Thanks for all your very talented work. Phil

  2. Hi Milen,
    Your program is realy fun to work with. I have som old MINITRIX tracks that i planed to sell Before i found SCARM. I now keep most of it for a comming Project.
    Thanks for your inspiration!
    If you want i can send you a bunch of Projects i made just because SCARM is fun to work with.
    I have an old catalog from MINITRIX from 1970 :
    RATGEBER FÜR PLANUNG, BAU UND FAHRBETRIEB (#56-9001-00)
    I have made almost every trackplan there.

  3. I found it refreshing to work with a software developer that was willing to accept comments, request testing assistance and add track libraries that other layout software does have.
    Other software expected one to purchase it, even while they are still under development.
    Thank you, Milen for creating a wonderful tool for model railroading at a very reasonable price.

  4. Hola, yo estaba usando SCARM recientemente. Lo encontré buscando una herramienta para diseñar mi maqueta H0. La verdad es que me defiendo con la herramienta pero no me ha dado tiempo a conocer y usar todo su potencial. Independientemente de esto me parece que es una gran herramienta y que ira mejorando y ahora más rápido si dispone de más recursos. Decirte que me parece un gran trabajo y que merece la pena apoyarte. Como he comentado, yo estoy empezando y desconozco el uso que le voy a dar pero aún así voy a comprar la licencia para ayudarte en este proyecto apasionante. Gracias y un fuerte abrazo desde MADRID ESPAÑA. Vicente Vidal

  5. Hello Milen,
    using your great track planning software tool for quite some time, I have nearly completed now a nice and very detailed 6,8 sqm Märklin HO K-track layout plan including base construction, landscape, signals, lamps, buildings and roads. I am also ready to share my layout plan here for inspiration of other SCARM users.
    Before I buy a license key for the 1.0 version, I would like to know, if this version offers the possibility to not only print the tracks with their center line but also lines right and left of the track for cutting the track support from wood. I need that because I would like to cut the wooden track support elements directly from the 1:1 print-out.
    Thanks and greetings,
    Wolfram

  6. Hello Wolfram,

    There are no changes in the tracks drawing procedure in this version. However, there are many ways to achieve what you want even now. Press “T” key one or more times to adjust the way tracks are drawn in 2D. You can select between center-lines, rails and outlines (along sleepers). Also you can use “B” key to see the roadbed mask, which is wider. And finally, you can set all tracks to be on a bridge mode while printing – that is even wider and will allow you to cut the wooden track bed.

  7. Hello Milen,
    thanks for your feedback. The bridge mode option is a great idea, indeed, for what I would like to achieve. I will try that one.
    Regards,
    Wolfram
