Yup you've got it right. There are two wyes in Sanford, one in downtown Sanford on the Aloma Spur. There are a few obstacles though, first the spur must be in service, next CSX can't be blocking the line, as a Conrad Yelvington (rock) yard is just down the road from the washer, thirdly the line has 5 MPH speed limits, so it takes a while to do the process. If Aloma is out of service than the Deland spur can be used (the switch can be seen right at Deland station). This spur is also out of service so that eliminates that option. So the only wye that is remotely close to Deland is Stanton Connection, south of Orlando, north of Kissimmee, and right near Orlando International Airport (a long way from Sanford). The Sunset wyes its equipment there when it only has one engine or is going WB. So the current plan is to add Northward facing engines to P002 Saturday night, have 002 wye them at Stanton so that Sanford has some southward facing engines necessary for the next days P001.
