Well, is it not a fact that Walter Rich borrowed funds from CSX and NS to outright purchase around 80% of the common stock of the railroad, leaving CSX and NS each with 10%, around the time of the Conrail takeover?
I would have to assume only the executor of the estate knows the exact situation with regard to what money is currently owed, if any.
If there is outstanding debt, the stock will probably have to be sold to cover it and settle the estate.
If the debt has been repaid, then it is a matter of how Mr. Rich willed the disposition of the property.
The property may still need to be sold off depending on how it is taxed, to what if any estate tax is required, to what if any additional income tax is required of those who inherit it, and so forth.
If any changes come about with regard to ownership or the operation of specific lines, STB filings will likely be required. If the ownership becomes public again, other filings will be necessary. Until such time as that happens, there isn't much sense discussing it. I would give them a chance to bury the man and read the will and start the paperwork.
I wouldn't expect to know anything for certain for another 3-4 weeks, if then.
There are so many rumors and stories with regard to what money was borrowed when and why and what track it was actually used to repair, it may take some time to sort out all of the legal details. I do believe that unless the contract ran out, the NYS&W is in violation of their Ontrack agreement by not running the RDC shuttles in Syracuse, as just one example of a situation that will require a lot of legal wrangling to settle things.
In the meantime, someone has to run the railroad. Given that Mr. Rich was sick for some time, I'm sure he was able to make some plans to prepare for this eventuality. I doubt you will see any major changes until any final disposition of the property can occur.
Auto racks and stack trains have to come from somewhere and go to somewhere. CSX owns the Little Ferry terminal and it's own routes as far west as the NYS&W goes. NS has it's own terminals and lines the entire length of the NYS&W also. It is highly unlikely a dedicated train would return to the line, except perhaps as an overflow from either of the other roads, particularly if major work is needed on one of their routes. As for excursions, it seems that most of the "toys" have been sold, or donated, away, which makes them unlikely events outside of perhaps the annual Maple Fest trains.
As for the SD70s, they make the road more money where they are now; it's more cost-effective to lease them out and buy older used power that can get the job done and be run into the ground and remanufactured for a fraction of the cost of a new unit, even for a fraction of the cost of lease payments on a new unit.
