There are other sites which have used combinations of the words "Digital" and "Rails" over the course of time. Given all of the various TLD's now available, it would be impractical to list all of them, but if this isn't the site you were seeking, use a search engine to find the site you need.
DigitalRails.com has no connection to DigitalRails.net, Digital-Rails.com, or any other site with a combination of the words "Digital" or "Rails", and any confusion with other sites is purely coincidental and unintended.
DigitalRails.com domain previously belonged to John Morris until March 2015, and was a redirect to DigitalRails.Net (which is still available today as a virtual railroading photography site).
There are other sites similarly named, plus variations on "Digital-Rails.com" which is the branding owned by John Stanford. John failed to renew in October 2014, and it was bought by "Acquire This Name, Inc." in February 2015, and they are currently offering it for sale to the highest bidder.
If you have questions regarding the current site, please feel free to leave them as comments on this page, and they'll be addressed as time permits.
