The LionChief wall wart outputs 18V at 2000mA. Supposing you plugged it into a Miller Engineering power distribution board; How many basic 40” X 60” loops could be powered from a single wall wart? Assume running the modern passenger sets that come in the RTR LionChief sets on each loop; Steam Engine Tender and three passenger cars with LED illumination.
What are the possibilities? … Most output in currently available DC wall warts: How many trains and loops could be operated under the supposed parameters?
