Train Railcars Metal Boom by The Recordist published on 2011/12/16 23:28:45 +0000 I've been after this sound for weeks and finally got one! It's a mile long train departing and when the railcars are empty they go Boom!!! when the train starts to pull away. This one was almost perfect, I was on the wrong side of the tracks. The train passing by in front was not quite past since I was at the last 100 yards of the train. Well, anyway it's one hell of a sound and I hope to get a few clean ones this weekend now that I found the perfect location.
