Although I understand what you are saying, Greenwood, I imagine there are concerns which we are unaware of. Regarding Tatsy's original question as to what can be done, this here is a start.
RR is obviously aware that their service marks are used on SR, and they did not have to allow this. Neither did SR have to allow it.
It would seem to me that both parties have prudently set aside any historic ill feelings in order to serve a greater good in the long term.
