The site says it is to be a mid-week service.
This follows a long-running local campaign (The Area News, Griffith's local paper, reported on this late last year)
It is interesting that they are planning to do this (obvious state election considerations aside), as there is a well known shortage of rolling stock, and the weekend service is already frequently cancelled for one reason or another. That said, at least a mid-week service would not be so much at the mercy of the dreaded weekend trackwork.
The WIN News Facebook page also has the story, as does the mighty Cootamundra Herald.
