Hello and welcome to the xtrkcad yahoo group. 

the current version of XTrkCAD can always be found at 

http://www.xtrkcad.org/

Follow the download links on the title page.

As this software has been released as open source, there is no need to register anymore. 

Your contribution to the project is always welcome. So if you create any interesting trackplans or library of track components (a parameter file) share them with us via this group.

thanks,

xtrkcad yahoo group moderators
