To those that answer thanking you in advance!
I am designing an HO system where all the vehicles I have purchased to date are DCC ready.  I was looking at getting the Bchmann Wireless System or the Direct Connect system to control the trains.  A nice forum person explained the DCC should not be used for DC trains due to possible burnout and many lac AC for accessories and will need a other power source!

Here it is I see they have DCC turnouts, what are the advantages and dis advantages of buying those switches over the standard remote switch.  What will I get, consulted a website but it was still to difficult for a novice.  If I buy DCC decoder switches will I have to run wire at all?

I will likely run 2 trains simul at once on this table, a trolley on sep line and a Lionel O scale on a 2nd level circling the lower HO, ON30 scale train.   I know a DC train and AC train should not be ran on a DCC system but can a DCC train be ran on a DC powered system?  If I have standard remote switches do I have to run wiring and stuff to the DCC system or to the sep power source I purchased.

Am I safe to assume that the new ez command is really just a controller for all train activity and you still need a power source for the set itself, or is this the power source?

If I need a power source, anyone have a recommendation (Model Number) on what  power supply or transformer would be best suited to run 2 trains and some light scenery activity, etc.  Must be DC/DCC current for it will be used on ON30 or HO size scale trains... Thanks Mike .

I am thinking of buying a Trolley ON30 scale

I know it runs on HO size track but is the vehicle true O scale in size?  I have an O Scale Lionel set will this look out of place running next to this set. IF not true O scale is it just slightly smaller and will it look OK?

It says also DC current does that mean I have to buy a special transformer or can I use my 80 watt Lionel transformer? 

Finally, how can you add bell sounds to a trolley if it does not come with it standard?
