Keith has indicated that ExE will have his own set of lightning rail prices, which makes me think we'll get some daily life expectations content to sort through this argument.
That will be good, I'd like to see a lot of the economic stuff I was hoping would be in mormisc in that. It makes a lot of sense for lightning rail routes to be structured a lot like how airlines use hub airports* where you might walk or take a horse/coach to a nearby city big enough to justify a lightning rail stop & spend the night because there's only a 0-3 lightning rail stops a day with the next one being two days out for really ass end of nowhere stops, then take that train somewhere you can transfer to a sharn (or where ever) bound train. Something that becomes extremely apparent if you start looking at the lightning rails lines in Rising though is that they pretty much only connect capitol cities & cities that happen to be close enough with basically(literally?) no branch/spur lines unless the gm drops them in or the players decide that becoming short line railroad tycoons will be interesting

* busses & trains do too, but not to the extent they are visible beyond localish maps & trains aren't as significant a factor in travel as they were a hundred+ years ago
