I currently have two separate DC EZ Track ovals running two separate locos.  One of the ovals has a left and right turnout to make a small oval within a larger oval.  I recently purchased EZ Command plus and both left and right DCC ready turnouts to convert that to DCC.  Now that ive done that im thinking about connecting the current DC oval to the DCC oval using more DCC ready turnouts.  Ive read that on DC layouts you can short circuit the system with too many turnouts.  Is that aconcern with DCC layouts as well?  Is there a general rule of thumb about how many turnouts or crossovers you can have on a DCC layout?

Why doesnt Bachmann offer accessories for curvred ez track like curved bridges, railroad crossing gates for curved track or roads that butt up to curved track.......etc.  Not all layouts are big enough to afford to run all of these things to or over straight track.  Thanks.
