Sorry, just catching up here.
I'd posted elsewhere that there are no plans for diesels at the moment, but plans can and do change. If there is one, it'll be a heritage unit. We'll know soon whether or not someone in the operating department wants to show one off. It's really interesting that a few folks from Europe have got in touch about the sans-diesel possibility, because they, like others, have discerning tastes in their train consist...
We have operated a number of trips with no diesels on NS, as has Southern 639. There is no official rule/requirement/insurance clause regarding diesels.
Four locations are under consideration, including the NKP elevated station which. While logistically a little more complicated due to the aforementioned reasons, it would be the ideal spot for a number of reasons -- parking, marketing, etc...The reserve moves aren't a deal killer.
We'll change crews in Peru like any other train.
Right now there are two classes with one other class potentially evolving (and since adjusted since our announcement.) They are economy coach class (re-purposed NS passenger cars, more modern interior) standard coach (vintage MidAmerica coaches, reclining seats, all vintage interior), and deluxe coach (lower level dome car.)
Reading that you may wonder what about upper level dome car seats. We are going to reach out to those who were part of the 2000-2005 rebuild from Allen County and INDOT -- many of whom were part of the grant approval and administration process among others -- who have yet to see and experience the 765.
Given the time of year and the consist requirements, first class and other dome cars (beyond the MidAmerica dome on our property already) are hard to come by, but I would love nothing more than a few more options for those interested.
