Thanks for the comments gents! This might make a nice layout to give to the kids or grandkids for this Christmas.
This includes a minor adjustment, stretching the spur adjacent to the station for greater length. There is now 22+" clearance from the turnout points to the bumper on the lighted-bumper track section, enough length for a hopper (9.75") plus a switcher. The docksider O-6-O is 9.75" long, and will work nicely for servicing the Morton Salt spur.
