@DoubleDAZ posted:They’re O-42 because I couldn’t get O-54 to connect given your desire to retain the blue tracks where they are. The only way I could get O-54 to fit is to replace the 10" and 30" like I did in the version with the crossing, etc.
Thank you, I will try to work with that general plan after my son finishes the bench work. I'll advise you of changes when the time comes.
