I have built several models in the past and some asked if i could give a clinic on my method. So i did a little RR Tower recently and thought i would record it at the same time.
MY work can be seen at the Mendota IL Railroad Museum in which i built a HO scale replica of the Railroad yards and downtown area.
Also in Cherry Illinois at the Public Library is the model of the Cherry Coal Mine. For more info search Cherry coal Mine disaster on the internet and my site will come up.
