The question of AC vs DC comes up quite often. There are a number of products (engines, control systems and accessories) which specifically state should only be operated on AC and this requirement should be observed. My layout is flexible and can run variable AC, variable DC and fixed voltage TMCC. Over the years, my experience has shown that many AC products will work on DC and in many cases (for example: conventional running) the results are somewhat better with DC. As a side note, successful conversion to battery power is dependent on proper system operation on DC.
