Will a DCC locomotive run on ez track do I need to stop now and buy different turnouts and crossings for future upgrades
DCC does not require any special track but standard turnouts need to be powered off of your old power pack. DCC turnouts can be controlled and powered by your DCC system.

This thread has some good advice on converting bachmann turnouts to dcc. Maybe it will help
