AmFlyer Tom, you mentioned converting your 21004 to Lionel Legacy. First, please don't. Second, may I suggest an alternate method? TMCC. I love it. You don't get any more sound than you do now by using the TMCC since Gilbert AF engines are not TMCC equipped as you know but you do get way better low speed engine control which is great for a switcher as you have. Plus I can walk around and not be tethered to one spot with the hand held controller you see. It also controls all switches or I can use the AF switch controls. Basically the TMCC acts just like a direct wired transformer contolling engine speed. Here is what I did.
All of the controls are mounted on a rolling control stand. That really isn't important to the TMCC but just my way of building a control center. As pictured you see the type Z Lionel transformer which has one side turned to 18V constant. The other side controls the section you see just in front of the stand. The 1133 setting there is used only for accessories and building lights and such. I do have other AF transformers I could have used as you see in the picture. Those 18B's, or the 4B in place of the Lionel 1133. The 18's were just too big in size. Therefore the 1133. I did use the 4B but for some reason when it was on for an extended period of time running accessories it got too warm in my opinion.
Now the down side to using the TMCC system is cost and finding the system since it has been out of production for years. I have had mine for years, all bought new from my then local hobby shop.
