I was just going through some of my dad's old magazines and found this book. It is 764 helpful hints for model railroaders. I have been reading up on it and it gives some good hints on what to with a problem. I have found it to be a helpful guide to model railroading. Some of the helpful hints are, rolling stock, freight cars, passenger cars, motive power, trolley, layouts-general, track, scenery, and some other things. Here is an example that i found very interesting: Wax Water, for a creek or waterfall effect complete with realistic bubbles around rocks or stumps, pour melted paraffin wax over the creek bed. If the creek bed is first painted to look like water, enough of the color will show through the wax to give it a realistic tint. The thickness of the wax will determine the color of the water. I find that pretty interesting. I would have never of thought to do anything like that. I just thought i would let everyone know about this. This book was bought back in the late 70's that that kind of gives you how old it is.
