Hi. I have developed a phone app for Android based smartphones, called Georeader, that could be of interest to you. The app allows you to write a text message about any topic and place it on a map of the world. When you near that area, the app will read aloud the message. (Please check out the website www.mygeoreader.com as it will make more sense). Right now it contains info on thousands of historical markers , historical building and bridges. Anyhow, being an avid rail fan, I have (just) started to enter points along the NYS thruway about former and current rail lines that intersect the highway. Each point has a little info on the rail line, where it goes or went, and if can ever find it,abandonment dates. The goal would be when you drove down the highway and crossed over a weed covered roadbed or active rail line, the app would tell you a short bit of information about it. The app range is pretty much world wide so this process could certainly be applied anywhere. If you would like to use the app in this manner and log the rail lines in your area, it is certainly encouraged. The app is free so there is nothing to lose. (Search the market for Georeader)
