I am grateful for this forum! I don't know where I would find answers at if not. I just bought my first train set with DCC locomotives. EMD GP40 and EMD FT-A locomotives. (by the way I have no idea what those numbers mean) I would love to know how and what sound systems are compatible with these. Also maybe what number or style of couplers they use. I know they are knuckle couplers but I've seen several makes like kadee but there are different types also

again my question is about turnouts. This time its about wiring. I am using the Bachmann ez-track remote turnouts. The green wire from the track to the switch is and only about 2 feet long, if my layout is on a 4x8 and I have my turnout at one end and my switch is at the other with my control center I need more wire. Since one end of the wire is connected to the track and the other end has a plug that connects to the switch, I'm wondering. do they make an extension or do I cut the wire and splice in the middle

I guess most people know this but I'm a newbie. I'm having trouble finding remote turnouts. Even when I look to order online it's hard to determine if it is DCC. It doesn't have the information listed
