Classic TMCC command connections

No, this won't work because you have your wire leads swapped at the track and also are missing a connection to your CW.

Red connector(black wire with white stripe) to center rail and CW "A" post, black(solid black wire) to running rails and CW "U" post, which is where you connect the Command Base "U" with a separate wire running between them.

Ok, so if I swap the leads, will it work afterwords?

Ok so I corrected the leads and put them in the right places. Can 22 AWG solid wire work for the separate wire connection between the U terminal on the Trasnformer and the command base’s U terminal?

Well, it can be any size as it does not carry any power.

So would the connection for both U terminals look something like this? I used a black 22 AWG solid wire to match up with the U terminal.

Don't over complicate it. It is literally a one-wire connection to the layout.

Ok so I have everything hooked up, but when I went to program my train and try to control my engine. I keep getting a red flashing light. I’m not sure what this means.

Normal operation.

The red light is telling you that it is receiving the command. As Rob says, normal.

Thanks everyone. I got my train running, and the train is receiving enough power go around the first loop. I’m excited to see what the future holds for my layout.
