It's the local between Rochester Goodman street yard and Batavia yard. It's been using a caboose/shoving platform for quite a few years now. Not sure how often it runs, might be daily Mon-Fri, or at least a few times per week.
The locals ID is B791. It switches the feed mill west of Batavia and leaves interchange for GVT in addition to whatever other work it has around Rochester. The feed mill switch faces east and requires a back up move of around a mile or so from Batavia Yard. I've seen it on a Tuesday and Friday in recent weeks and it may run quite often during the week.
I don't know the symbol today, but it's a different local that covers to the east. B791 covers Goodman St. to
Batavia, the Charlotte Runner to the "box shop" and on certain days the West Shore to Genesee Jct.
