thanks again for all your help.
Larry: are parts for used transformers hard to find. i love rebuilding things and enjoy fixing any thing. where is the best place to find used transformers? I am from Ohio and i just started looking for train shows and i can't find any in my area. It looks like a few of the shows were in Dec. of last year and Jan. of this year.
so if you all don't mind helping me out again i would like to know the best places to find parts for Lionel transformer and also Lionel engine parts. I am going to try to stick with O gauge and S gauge.
thanks for your time and you comments

Hi all
Please read and help, i know it is long but it is my first email and i need this help so much PLEASE 
I hope i put this in the right place. i am kind of new to forums never had time to use computer for fun before.

Got injured and now stuck in wheel chair and had to close construction company. i loved to build home so now i have replaced that love with building  in a smaller scale 1/48 of what i was use to. now i am getting to the point of figuring out the wiring and control system for this layout. i have 35 turnouts and will have a lot of cool ad on like all kinds of lights and gates and anything else i can find or make so i am in need of some help figuring out what all i need to control all of this, i don't mean every piece of wire, i just want to know what is the best controller and what all accessory to it will i need. i think i have leaned toward legacy. but i would like to know what equipment i need to use MTH locos later. I have about a dozen or so postwar Lionel engines so i want to run the conventional. maybe one of them i will try to up grade and put board into it.

My room is 30 by 25 kind of an L shape for now with more room to grow.

Please help me with a list of everything i would need to have to be able to control all the old and all the new engines i will running. conventional and controlled plus what i need to run MTH if i buy some of those engines. please forgive me if i am not calling things correct. i am NEW and need you help. I have read everything i can on the internet for the last 2 weeks and they all say different things so i thought your group sounded like the best place to ask. one last Question am i making the right choice with going with legacy or should i go with MTH DCS. or both. Using Ross switches or self made ones. using tortoise switch controls. 0.148 3 rail o gauge. using .125 third rail, going to wire it so i can run my old engine conventional, but want my controller to do all the controlling, i read legacy does that with no problem.  what are all of your thoughts. I know this is long but this is the only thing i have not decide on. i think i am going to get both but start with legacy. so what all do i need to order. what all do i need I am sure there is a special box to run conventionally, just need some one to tell me what all i need and is there a special wiring harness or cable i need. thanks for all your help.
