It appears that Jackson and Lansing are "on the way":

When accepted, there will be twelve of 'em on the property. That means there will be adequate protection for 19-20 and 97-98, and that the "rare sighting" will be an H-D.
Theoretically, along with 8400, Amtrak could restore full service to 48-49 now, but they could easily "come up naked" for protection at the outlying points of CHI and NOL, as well as having to play "Rob Peter to Pay Paul" at SSY. Likely two more need be delivered before 48-49 can be in play. Let us not forget that Diners have a higher E-Cleaning cycle than other cars, and if one of our multipeded friends is caught "deadheading", out comes the car and "under the tent" it goes for a fumigation.
