Welcome Steve, or should it be "welcome back"... A styrofoam based layout from 20 years ago seems (to me) to be pretty advanced thinking for the time. Probably the biggest change is DCC - digital command control - with which it is possible to drive the individual engine, not just change the power to the track. There have been many advances in materials, quality of electrical components, detailing of engines, etc, but one might argue that it is just the natural evolution of the item in question. DCC is a "paradigm shift" - a completely different way of looking at how something works, or could work. Don't be too baffled though... as in the past, many things are the same, or are similar. If you knew how to solder then, you know how to now (for example). And of course, if you aska question, you will get three "right" answers - you'll just have to decide what works best for you. Andrew
