When Boardman was CEO I used to know several people in the planning department. Naturally I tended to come up with brilliant ideas involving tweaking a schedule by an hour to get some marginal gain (at least theoretically). We had lively discussions about those. The gentleman who was the right hand man of Boardman once explained to me that unless there is a huge life or death issue involved you never go to a host railroad asking for a schedule modification, since inevitably that brings out the counter-proposals to slow down the train to fit better in the freight flow. His point was that unless perceived gain was large in terms of revenue/ridership, it is better to let sleeping dogs lie and get enforcement of what we have. I am sure the situation is no different now, now that the STB thing is leading in general to hosts requesting slower schedules before they can guarantee compliance with the metrics.
So I think I am on pretty solid ground when I suggest that the proposed shuffling of EB or any schedule of this sort is not going to happen, specially if it involves maintaining total running time or reducing running time, unless it originates from the host railroad. Just my educated guess for reasons described above.
