Arnold your continuing to make great progress…keep it going. I’m glad your working on a loop at a time and verifying your work as you completed it. That’s the easiest way to troubleshoot work that was just completed.
Yes, backing out the screws was necessary to loop around the easiest. The terminal block looks good and will serve you well. Is the tail you left long enough? How do you plan to daisy chain? Remember you have the mounting screws at each end, and you will need to double up the wire under the first screw on the new block.
Question for you, how are you connecting the power lock on wire to the stranded wire running to you MTH block?
Keep making progress and the trains will be running in no time.
