Is there a certain kind of switch  i need size Volt or Amp?

Is this how it should look like?

I'm using EZtrack Black. And im using a MRC tech 6 sound controler.  I have one bachmann loco with sound and one with out. i would like to run them both on the same track. But not at the Same time. Is rthere way to put some kind of blocks with switches so i can do that? if so can some one tell me how?

The circles show where i want to put the blocks.



And can some one tell me what rail is the positive rail>

Do they make a locomotive with sound that will work on a dc? I have EZ track (Black) With  the regular controller. And i was wondering if i can run a DCC locomotive on it with sound? Or will i need a different controller? And if i do can some one help the poor person out and tell me what i need. Plus a less expensive locomotive?

I need to cut out a oval pattern with 2 straights on plywood so i could elevate my second train. I need it 3 inches wide all the way around with the ez track in the middle. what im having trouble with is messuering the curvse to cut. can any one tell me how to measure it si i get perfect curves?

what about how one of the outer wire jumps to the middle when it goes into the turnout? which one would be power wire?

Nice job. Where do you get kits like that. I'm a new guy to model railroading. And i would like to learn on how to work with the kits.

I need to add extra wire to my green 3 wire turnouts.  But i dont know which wire is which in the green 3 wire turn outs. I'm using colored wires to wire to the switch. As in the first pic. As in the second pic. It show the 2 wires are flipped before it goes into the switch.  Can some one please help this noob?  lol Another noobie question. are all bachmann HO track called on30?

Thanks for your help

i just bought left and right turn outs. and was wonder how to hook them up to my power pack. as you can see in the picture of the wire should i cut the ends of the wire to attach it to the power supply? and can i hook both turn outs together?
