Hello,
Earlier this evening I was out railfanning in North Charleston, SC. A manifest came out of the yard and stopped short of a grade crossing, at which point something under one of the centerbeam flats, possibly around the middle of the car, started clicking. It lasted for about 20 seconds, then reduced in frequency before it stopped. The train reversed about two car lengths, then stopped, and the clicking happened again. I thought it might be a defect on the car, but a few minutes later the train left. I've been around a lot of freight cars, and I've never heard this before. Any ideas on what it was? I can provide a video once I have it edited and uploaded.
