In the early days of Stereo there was some very good LP recordings of railroad sounds. My favorite was called Rail Dynamics and was recorded near Peekskill, NY. It was described as ‘rainy night along the New York Central’. Mostly steam with a few diesel streamliners as it was done in 1950. Another was ‘Railroad Sounds - steam and diesel’ and described as ‘sounds of a vanishing era.’ It was recorded along the IC.
