One of my favorite aspects of model railroading is detailing engines, so, I plan on doing several engine detail projects, including some engines that don't even fit into any of my operating schemes. Pages for completed, current, and future projects can be found via the navigation bar.
With my track plan, it is not practical for two trains to operate at once. So I didn't feel any need to wire the layout for two-cab operation, and I don't have any need to go through the effort and expense for converting any of my engines to DCC. I'm not adverse to doing it in the future. It's just that for now, standard DC is just fine (and a bit cheaper).
