There are some amazing photos in this thread, and should be included in that other thread about "My Best Railroad Shot Ever".
Personally, I use my smart phone, iPhone 5c, I think it is. Before that I used a kodak Easy-Share digital camera. And way back in the day, I used my Miranda Sensorex SLR, I purchased while on the Ho Chi Minh Trail back in 1968.
I was pretty good with the Miranda. I hadn't used in in many years as life took over, kids, house, etc. When I got the Kodak camera as a gift, I thought it was the cat's meow. Then three years ago, I obtained my smart phone. And not long after bought a mac computer. While taking some lessons at the Apple store, i asked the gurus there why I was having a hard time coordinating my kodak camera with the new computer. The answer I got was to retire my Kodak and use my smart phone as it has a much better camera. They were right.
So to answer the question posed, it's my smart phone that I use for rail fanning photography.
