About Us:

Christina and Jeffrey Rossi started this site back on July 02, 2011. Our main focus was to publish digital photos and videos for the RailFan Hobby. In late 2014, we opened our site up as a General Forum for RailFans in Arizona. At the same time, we continued to post our photos and videos to the site.

Then we got into the ATCS Monitoring Project, by helping out Jon Adams with one of his sites that went down due to a Lightning Strike. We got the PC back online until we can replace the damaged PC. With the ATCS Project we (Christina and Jeffrey) as a team completed the following projects for Arizona and have more to come:

Looking for More Hosts:



We want to thank everyone that has helped us with Donations to keep the project(s) moving along. We also want to thank our Site Hosts that allow us to install our the equipment at their respected locations.

Our dedication to the RailFan Community: we have an automatic system that monitors all our servers/sites. If something goes down, we are automatically alerted to it via Text (SMS) message and Email.  We also monitor all the systems and push out updates during the night hours when there are least amount of users.  Between Christina and Jeffrey, we almost have24/7 coverage.  We stride to get the system back up as soon as possible.

Support Our Efforts by Donating

Our site is FREE of charge. However, the development and maintenance of our site, ATCS Monitoring Systems and RoboFoamer takes a significant amount of time to put together and maintain, with raising ISP and Server Costs as well.  If you find the coverage it provides useful, and that it adds to your enjoyment of railfanning, consider helping to the site's construction and maintenance cost with a donation of $5, $10, $20 or more by clicking on the PayPal "Donate" button below.  PayPal does not require a user to have a PayPal Account if you are using Credit/Debit Card.  We intend the donation process to be transparent and will keep a running total published on this page: Coming Soon. If you wish to have your donation acknowledged publicly, please add a note when you send it in with any other details. Donations will go toward server expenses and the potential for new server locations in Arizona and parts of California and New Mexico. By donating, you will be a valuable part of our effort, and allow us to procure quality, reliable equipment for future sites.  Please note that your donations are not tax-deductible.
