I was looking at the Lionel RTR catalog and noticed that all the new Lionchief sets now come with an larger 54W power supply. This
should solve any problems from past sets. I also noticed that a "Plug & Play track is part of each set so if a customer chooses to add
an accessory, there should be enough power for that as well. It always pays to read the fine print.
P.S. The catalogs are a lot easier to read off Charles Ro's site.
