ERR question

Thanks Mike!

Does TMCC Compatible not automatically equal DCS compatible?

It is basically a Lionel TMCC system with or without Cruise and sounds.  Your options on what to put in.  So it is a TMCC based system.  PS-2 Upgrades are a DCS system.

Yes you can run TMCC engines via DCS, but you need the TMCC/Legacy command base to have command functions.   G

A DCS system will operate TMCC equipped units/locomotives.  Some features may be lost.  

TMCC equipment, Command Base/Cab1 will operate DCS units/locomotives in conventional mode via a TPC (Track Power Controller). 

Neither is a real compatibility match, both systems are priority systems.  The ERR system uses Lionel technology.  

yes to al the above...i put one in a k-line 0-4-0 switcher and WOW !!! made it run REAL slow now its a great runner and not a toy.conrail john

IMO, TMCC is the least expensive way to get started in command control. Most of the time you can find a used CAB-1 and base for about $100. Then add a ERR ACcommander (about $75) to your postwar loco and now your operating in command control. 

You can also sometimes find used TMCC locos on eBay for under $150. 

True!  If you want cruise and if you want sound, it'll cost you extra.
  I had the Cruise Commander module in my WBB E7 for a couple of years before I realized it was full Command , I had been running it conventional until then.
