Can I replace the wheels on my Bachmann 0-6-0 with traction wheels??

Does Bachmann sell traction wheels for a 2-6-0 and a 0-6-0???

Where can I find the cv list for Bachmann HO #51807 Alco 2-6-0 Mogul steam loco???

I would like to get the same style/type coal load ( shiny facets looks like real coal) that is in the 2 bay hopper car #19505
for the 4 Quad hopper #17627. C an you help me with that?

I have a new HO EMD GP7 loco (item #65604). I would like the sound NOT to come on as soon as the track is hot. I would like the start up sound to come on when I call the loco up. What CV and value should I use??? Or does this decoder not support this function???

I have 3 Bachmann loco's  I would like to convert to DDC. They are EMD GP 35 Santa Fe #2897, and two train set loco's, an EMD FT Santa Fe, set item #00647 and a steam loco Chattanooga, set item #00626. What if any decoder will fit them?

Also I have a Bachmann 4-4-0 that has a decoder E 20395, ver. # 046 item # 4495. what functions beside the light does it support? I have an NEC Pro Cab for DDC operations.
Thanks

I have a DC layout. I need some turnouts. Looks like Peco fits what I am doing. However I don't know which is better, the Insulated or electrified? Any advise would be very appreciated.   

Would it make sense to solder feeder wires to the rail joiners as one connection?

Can someone tell me what couplers come standard on the Bachmann Silver Series rolling stock. Are they short shank, over / under / center mount etc??? Just getting into this hobby and I have no clue, but am learning, I think.

I am trying to understand  uncouplers and how they work. Are they electrical and or magnetic. Thanks

I bought this loco. Being new to this I noticed that this loco needed more power to get going. One of you folks said DCC is that way and to remove the decoder. Other than that this is a very nicely detailed loco and runs great, no wobble.

are there ways to have sound on a dc setup?

I have an HO Glacier gravel company building with two bays.  I would like to run track to both bays. However the width of the center column is 1/4 inch. So that makes the EZ track ballast have a 1/4 inch between each track. My problem is what or how do I use to (why or turnout) to select either bay. Thanks for your help.
