I have a Legacy system (990), and want to run convention trains. What units do I need, or can I just use a dpdt toggle switch and alternate between Legacy and direct Transformer connection. I have 3 different tracks and would like to run Legacy on one track and conventional on a different one. The various modules get confusing as to which one if any I need to have. (Transformer is the ZW-L, one with the meters.
Thanks for any advice.
