After years of Marklin Z layouts, I'm building a HO layout to return to my model railroading roots I have two possible layouts, one of which is 9x12 and one of which is 10x16. To be honest I'm not all that impressed with any of the DCC systems, as the last one I used was the new Marklin HO central station(loved it), and the user interface is much better than any of the button sequences I seem to find are the norm in US systems. My local shop recommended the Digitrax Zephyr system, and so I bought the entry package thinking it would be fine. At that time I was planning a smaller layout, so now I'm having second thoughts. I have 7 new steam engines, all DCC and sound equipped, maybe a little much for the size of my layouts, but the big steam engines are what brought me back to HO away from Marklin. The layouts have between 25 and 35 switches, all DCC controlled, as well as a turntable and various other components such as lighting, signals, etc. I'll want DCC. I'll probably be expanding either layout with a larger yard at some point so I'd be adding a reasonable number of switches later. Complexity of the system doesn't bother me, I'm looking for optimum functionality. I really wish someone offered a system like the Marklin but I can't seem to find one. I'd love any suggestions from the better DCC informed.
