COMMENTS RE: RR-TRACK software. I bought the full version a month ago and have since designed my large dream layout and enjoyed the process, to my surprise. You can buy it with very complete libraries of all common track types including flex track, and also dozens of toy train accessories from Lionel, MTH and Plasticville. I'm experienced with Windows business applications (Word and Outlook, especially) but not at all with CAD software. For example, I couldn't draw the first oval with 3rdPlanIt a few years back. RR-Track is very well designed to use one's Windows skills, and given that baseline I found it pretty easy to learn. If you need Windows skills, I strongly suggest you invest in one or two basic, one-day Windows courses with a computer training school in your area, the kind a business would send an employee to take. It may cost you $200 to $300 for the two courses (total), but you will be so much more able to learn, and take advantage of the excellent work done by RR-Track's creator, that I suspect you'll be glad you spent the time and money to acquire the smarts about Windows basics.
