To convert to DCC,what do I have to look out for when using so called
Thinking Switches,in other words,rails being energized only in
direction set.Does any different application apply for operations in
DCC?

DCC requires good solid electrical connections and contacts. The mechanism that selects which rails will be energized is likely to be a puny sliding contact switch or only points of the moving rails. This might be adequate for DC but with DCC a short circuit on switch rails and the power available from a good DCC booster in combination of the relatively poor electrical contact at can cause havoc. Electrical resistance of that contact may limit current such that the booster does not trip off but can cause the sliding contact to get hot enough to melt plastic parts of the turnout.

Thank you for your reply.What kind of switches will be best for HO=DCC
use?I'm presently using Fleischmann-Profi with motor and ballast.Are
switches,which have all rails energized better? Thanks again.
