thanks Ken, I appreciate the input - I plan on splicing the end of the red power wire that connects to the Bachmann DCC controller and connect it to the 2 pin plug of the NCE Power Cab (Cab) - the other end of this red power wire is connected to the Bachmann EZ terminal rerailer track - now, this EZ track terminal rerailer has plugs on both sides of the track, so for the Snap It connections, I can use the other side of the terminal rerailer track (right?) because you mention in your Option 1 "from one side of a terminal rerailer" - am I correct?

the Cab offers more flexibility, including the process of coupling and uncoupling - currently, I'm using the Bachmann EZ Command Center controller (DCC controller) - it was so easy to use, and I liked the ability to run several locos on it, that I bought a second DCC controller for my 2nd layout - however, after about a month of using this 2nd DCC controller, it stopped working - I always have the right address, because I can get sound & lighting on all locos, but the locos do not run, either forward or backward - do you know anything about that?

I am using Bachamnn's EZ track - can the Snap It still be used with Bachmann's EZ track? - I know that the Power Cab can be used with my Bachmann EZ track by splicing one end of the red power track wire to connect to the Cab's 2 pin plug, with the other end of the red wire connected to the Bachmann EZ track terminal

I understand the green wires tie into the 'Snap It', but how does the Snap It connect to the NCE PowerCab

Recently, my Bachmann EZ DCC Command controller stopped working - the digital locos will produce sound and the lights work, but the locos will not run, either in reverse or forward - it is not the case of having the wrong address, because as I test each loco individually (there are 5), I first choose the appropriate address for each one, then select the Function key, then test it's lights and sound - each of the 5 work for light & sound, but none of them run - I first removed all but 1 of the locos to see if maybe there was an "overload", but that individual loco (proper address selected) did not run, just lights & sound - any ideas?

I understand the green wires tie into the 'Snap It', but how does the Snap It connect to the NCE PowerCab   - right now my turnouts green wires connect to the remote switches, but I would like to throw these switches using the Cab, and not the Bachmann EZ Command controller (which works great, by the way) - another nice feature I like with the Cab is the de-coupling process

I throw the all turnout switches with the black box that comes with the track, not the DCC Controller - some of the biggest features with Bachmann's DCC controller is running more than 1 loco at a time, and very easy to use

thanks for the info - I'm currently thinking about the PowerCab, probably in a few more months - sounds like you are saying that I can use the Cab in conjunction with the Snap It, I will have to more research

I'm using a Bachmann EZ Track system - my 4x 8 layout has 8 turnouts, and I throw each switch using those small black boxes, powered by it's own Bachmann analog controller (power goes directly to the 1st switch box, and the other 7 switch boxes are linked to this 1st box) - works out great in conjunction with the Bachmann DCC controller that runs the 3 DCC engines and 1 analog (with the F10 key) engine 

I'm thinking of using the NCE Power Cab with the NCE Snap It Quad - it looks like I will only be able to use the Snap It to control 4 of the 8 switches, is that right?  can I tie 2 Snap It together to run 8 switches?

thanks man, I really appreciate your help and comments - if I use the NCE Power Cab, it looks like I will have to splice the red, EZ track wire in order to use the Cab's 2 pin plug  - currently, my Bachmann EZ DCC controller (works great, by the way) has a red track wire - this red wire plugs into the track, and the other end plugs into the controller - the end that plugs into the controller will need to have the plug cut off, then splice and expose the 2 wires in order to use the Cab 2 pin plug - I'm thinking about it, we'll see - the Bachmann DCC Sound on Board diesel engines are great with the default sounds, but why not have the ability to choose too, right?

thanks again

thanks for your help, I appreciate it - do you have any recommendations from the replacement of the EZ Command Center controller? - I would need something that plugs into the track like the EZ controller does, right?

I have the Bachmann EZ Command Control Center (controller) - I use this on the EZ track -the sound is excellent, but want to have the ability to change the default values -sounds like a change from the EZ controller might be needed

so I have the 'GE Dash8-40CW', with a default value of 0 (Nathan K5LA) for an air horn - how do I change the default value?

how is this accomplished? - it has the default air horn (both Long and Short), but how to I choose another horn?

the track switches are not DDC switches - must use the analog 'Plug and Play' controller in conjuction with the DCC EZ command controller center - the 'Plug and Play' controller ONLY has the red power line going to the switches and NOT the red power line to the track - and the DCC EZ command controller center DOES has the red power line to the track - I am NOT using the DDC switch track sections - any help?

the Controller with Plug In Wiring sends power to the track and to the switches (turnouts) - it has a red power wire going to the terminal track section (to power the track) and it also has wiring to send power to one of the switch boxes (the switch boxes "snap" into one another , so all 5 are powered) - it does not work properly on the main line, as I cannot go in reverse with the engine - all 5 switches continue to work (the main line has 2 switches to pull the train into (and back out of) the inside track of the main line (the main line has both outside track and inside track) and enables me to access the spur lines from the inside track - the inside track also has 2 switches, and one of the spur lines has 1 switch (for the total of 5 switches) - as stated, this Controller with the Plug In Wiring on the main line does not allow me to go in reverse - however, when I tie this Controller with Plug In Wiring into the upper line terminal track section with the track power red wire, the engine can go in both directions - also, all 5 switches on the main line continue to function properly - now, the "simple" Controller (has no Plug In Wiring) that use to send power to the upper line is now sent to the main line, and is working properly (engine goes forward and reverse) - the upper line is an oval with no switches

one of my first steps was to swap out the Controller with Plug In Wiring with another Controller with Plug In Wiring, which did not work - what eventually worked (and I don't know why) was to swap out the Controller with Plug In Wiring on my layout (for the main line) with the "simple" Controller on my layout (has no Plug In Wiring) that previously sent power to the track for the upper line - as stated, it now sends power to the main line - the power sent to the switches still comes from the Plug In Wiring Controller, but the power for the track in now sent to the upper line - so I do have a "work around" now, and both lines are now working, just not how it designed

remember, these are Bachmann "Plug N Play" Speed Controllers, I do not need and special wiring, etc - you just plug the red power wires into the track and go - and in the case to power the switches, you just plug in the wiring to the switch box from the Speed Controller that has Plug In Wiring

I really appreciate the input I have been receiving - it a great "sounding board" and you guys have helped me along the way - what bothers me is that I still do not understand why the Controller with Plug In Wiring cannot work properly on the main line, but works on the upper line -  many thanks, and I'm going to keep "digging"

I have found a work-around...although, I still do not understand why my track suddenly went "bad" and started only going in one direction (after working fine for a month)...  my layout consists of #1, a main line with 5 switches and #2, an upper line, which is an oval track with no switches-it's elevated and goes over the main line in certain areas  - regarding the main line, power is sent to the track with the Speed Controller with Plug-In Wiring to power the track and the 5 switches... all 5 switches still work fine, but the problem (as stated earlier) is that you can only can go forward with the engine... now, the upper line (oval track layout with no switches) has power sent to the track with the Speed Controller - however, this Speed Controller does not have any Plug-In Wiring - a "simple" Controller was used because there was no need for it, there are no switches... the upper line has always worked fine (engine forward and reverse)... but what I did differently this time was I still used the same 2 Speed Controllers (the Plug-In Wiring Controller and the simple Controller) - but the power to run the engine on the main line is now from the upper line "simple" Speed Controller, and the power to run the upper line is sent from the Speed Controller with Plug-In Wiring from the main line... so, the Speed Controller with Plug In Wiring sends power to the upper line track and sends power for the main line switches - the simple Controller sends power for the main line track - I need 2 Controllers (the Plug-In and "simple") to fully run the main line - I need only one (the Plug In) Speed Controller to run the upper line

remember, these are Bachmann Speed Controllers - one Controller has Plug In Wiring to power the switches and the other Controller only sends power to the track- it's a quick and easy set up, and until now, had been quite reliable - earlier, I had changed the red power wires, changed the terminal track section, swapped out the Plug In Wiring Speed Controller with another Plug In Wiring Speed Controller
