@Ted S posted:My main concerns are whether DCC and Legacy can operate on the same track at the same time, without interfering with each other.
Not completely. Electrocouplers on Legacy won't work (And possible will overheat and burn out.). Also, on parallel tracks the Legacy signal can get blown out when a DCC train passes the Legacy locomotive.
Now, if you do as above and switch your track between a Legacy and DCC signal they'll run just fine. It's when both Legacy and DCC are on the track at the same time then the Legacy signal suffers.
@Ted S posted:Also, whether DCC can extract the slow-speed performance out of a loco like MTH's Protosound-2 can (i.e., without the benefit of a tach sensor on the motor flywheel.)
If you are talking about MTH PS-3 locomotives, just like I understand with DCS, I have found my locomotives don't run well until 3-4smph. Now if you do a DCC upgrade that will be different. I upgraded a Lionel conventional Dockside 0-6-0 locomotive to DCC with a LokSound L v4 decoder and without adjusting any CV's it runs super duper slow and smooth.
