I found this in the binder with a bunch of photos I took of 556 about 25 years ago. I've probably had it for 20-25 years. It looks like 554 doesn't have a cross-compound compressor, so it must have been shortly after it was received. If you use your imagination those may be Quonset huts in the background. It looks like it was taken at the same time as this photo without the second locomotive cropped. In this one the steam pattern is different but the same rocks and bushes are in the photo. I was spending a lot of time at MATI then so may have bought it from them. - Dick Morris
