Is the spectrum sd 40-2 n scale decoder ready ? What decoders will fit in it ?

any suggestions on the best way to solder feeder wires to 5" pieces of ez track.  Location, drilling, size of wire and soldering?

I recently purchased the n ez turntable. It has instructions for hookup with dc using a bachmann powerpak and for installing a decoder and usng it with dcc.  I have an nce dcc system. I would like to use the switch that comes with the turntable, but use dcc for the trains.  How do i power the switch?  Ac, dc, or track dcc power?

I purchased a new  turntable. I want to connect it to a dcc layout. I will have powered track coming in at position #4, but I want to use the supplied direction switch that comes with the turntable. There will not be a dcc decoder in the motor house. How do I connect the plug end of the control switch. Do I use track power from the track power bus or do I use 16 vac from the accessory terminal block that powers my turnout switches. It looks like it runs on track power if I was using the dcc decoder. I have an nce power cab for dcc track power and engine control. This would apply to n scale or ho scale new dcc ready turntables.

Does anyone know of a roundhouse that will match up with the new ez track n scale turntable ?

Does anyone know of a good sound dcc decoder or dcc engine and sound controller that is not too hard to install in my bachmann n scale current model F7 with dcc already on board. I have not opened it up. Does it have a dcc board that can be replaced drop in style or have a plug to plug in a new decoder? Would the soundtraxx tsunami micro TSU-750 (827001) or the MRC 1959 n diesel universal decoders work? Thanks

I am having trouble getting my kato spring loaded knuckle coupler on the santa fe super chief passenger cars to couple to my bachmann dcc f 7 a or b units with ez mark 2 magnetic knuckle couplers. The kato couplers are smaller and are made differently and wont hook up and stay hooked.  I am considering replacing 1 ez mate coupler with MT 1131. However, I tried to couple the kato car to a micro trains box car with MT mag. Couplers and they wont mate up either. Is there a kato conversion for the bachmann short body mounted, or how can i mate the car to the diesel short of super gluing them together?
