Hi Phil, As you can see in my signature, I am a Rocrail user for my LGB layout. I have involved in adding support for the Elite into Rocrail, since the main programmer of Rocrail strictly sticks to the Expressnet specification (contrary to the Elite firmware). Not hampered by experience, my guess is that Railmaster and Elite, belonging to the same 'family' can work in perfect harmony. Since Rocrail is free, why not go ahead and give it a try, I have not found anything that I can not do with Rocrail. Keep in mind that the learning curve can be steep, But there is a very helpful forum and some instruction videa's. Common beginners fault: Rocrail is not a track design program, less is more is the golden rule. I am sure that Rob will also say something about Rocrail.
