How to design track plan on computer

Hi ,I already have a track plan set just want to design it online. I f anyone knows a program or site to use please tell me thanks in advance

What scale?? I have used Atlasrr.com’s Right Track program. The only real drawback is that the widest radius curve is 24", but I was able to work around that using flex track.

Medina i am using N scale. Do have to download right track

Another good program is XTrkCad. It is also free. Website is http://www.sillub.com/ . The link for free registration is about halfway down the page. No matter what you have to do your homework first. If you can read John Armstrong’s book “Track Planning for Realistic Operation”, maybe look at another of his layout books, and possibly one of Iain Rice’s books it will really help you as far as things to think about while creating your design.

Trainfreek, yes, Right Track works for N-scale, too. It just uses a different set of track and structures libraries (included with the download). [:)]

thanks guys[8D]
