What factors are involved in selecting appropriate turnouts to use? For instance when would a #4 be preferable to a #5 or #6 or even a WYE?

Thanks blwfish but is every 5 to 8 feet overkill or what?

I am considering converting to DCC. I run two somewhat parallel tracks of approximately 28 feet each with 2 turnouts on each with EZ Track. They do not currently intersect. It has been suggested to me that I consider adding additional power every 5 to 8 feet of track if I convert to DCC. Is this necessary to convert to DCC?

Thanks for your help. I adjusted everything on the turnout to be tight however I think its the trucks. It appears the car shifts too abruptly for them to handle.

I am relatively new to this. I did it years ago when there were fewer options for things like track. I have used an EZ Trak layout to get back into it. I used something called a Remote Turnout, both right and left, for the EZ Trak. There are no numbers associated with these. The problem I have is the passenger cars seem to derail consistantly on them. What turnouts should I be using if these are not correct?
