There is a two part video put out by A & R on the ET&WNC that is a ride on the line in the 1940's before WWII and after WWII. It's all color and has sound. There are several ET&WNC books, one by Mal and the other by Johnny Graybeal. There is an ET&WNC society that put out a lot of information on the railroad. In addition there are a series of small softback books on engines, rolling stock, depot's, etc. Lastly there was a two part series in the NMRA publication back in the 1970's that Bob Richardson wrote about his trip on the line.
