Recordist Paul Virostek has published a great article on recording Train sound effects.
Train sound effects are one of my favorite field recordings to capture. Whether they are subway sounds, monorail sound clips, trams or streetcars, high-speed trains or electric train sound effects, I find that trains or “rolling stock” offer endless different sounds to record.
Similar to construction vehicles (like the drilling rig sound effects I posted), trains are mechanically specialized and incredibly complex. This means that they have potential for unique and interesting sound effects.
