It has an entirely new layout and contains most of the material from the previous sites. There's plenty of photos and quite a few slideshows. Compared with the earlier sites, the text has been substantially extended and tourism related information added. Each page has a link to the corresponding site in French, and vice versa.
The site is at railtrain.org/attcv/. It is marked as still being in a beta version and one can expect it to be frequently revised in the near future.
NOTE - This site was closed in March 2014, without any replacement.
