Here is a very short sound video that I shot yesterday morning before our layout opened for the final day at the Southern New Mexico Fair. Yippeeeeeee ! ! ! The refinery background is too loud as I forgot to turn it down for the "empty" layout room. I think you will catch the skip in the loco sound caused by the dirty track at the time. A little alky cleanup and all was good.
The sound on that steamer certainly carries. Seems like the real thing, where we could hear them coming from a long way off.
