They go by me too fast to get the numbers- but today 7/29/06 the stars lined up and I was able to see both CZs and SWCs. All of them had 2 sleepers on the hind end and all were in the latest paint scheme. In fact only the diner on #3 was painted in the previous scheme and perhaps a coach on #6 that I could see.
Which would only serve to confirm that the only way to identify a refurbed sleeper is by number, since no diners and almost no coaches have been rebuilt, yet they are all in the latest paint scheme.
Why would they rotate the cars through Beech Grove just to put new stickers on them then send them back out without doing any sort of refurbishing? That sounds crazy. While I have not ridden the CZ lately, I rode the SWC back in March and the coaches looked internally similar to those I've encountered on the EB. Are we talking refurbished or rebuilt? I take refurbished as a cosmetic overhaul- new seats, carpets, etc as well as a re-stripe on the outside.
I'll be on the EB in October for a short trip so I'll pay closer attention to the details.
With the exception of some cars that were wrecked and required rebuilding, most of the sleeping cars have only been refurbished, not rebuilt. Almost all of the 41 of the Superliner I sleeping cars that I mentioned above, have only received new furnishings. The A/C, plumbing, heating, and the electrical systems remain original and have
not been rebuilt or replaced on the majority of the sleeping cars. Everything is cosmetic. I probably shouldn't have used the word rebuilt in my reply above, since very little coming out of Beech Grove is rebuilt.
But just because a car has the new stripes on its side does not mean that it got rebuilt or refurbished. Cars go in and out of Beech Grove for many other reasons, aside from needing a rebuild, a refurbishment, or even a new stripe. The most common reason being an overhaul. But my understanding is that an overhaul is a far cry from a full refurbishment like we were seeing in the Superliner I sleeping car fleet, until the program got cancelled last year.
AFAIK, an overhaul means fixing things that are broken, replacing cushions that are really in poor condition (perhaps even all cushions), as well as dealing with certain FRA mandated inspections and parts replacement. A refurbished sleeper means new carpets, new cushions and mattresses, new curtains, new wood paneling in the car at a minimum. The full treatment also got new lights, new bathrooms, and new showers. But beyond that, nothing that makes the car actually work was touched unfortunately. AFAIK, no coaches or diners have received such treatments. Some lounge cars have been updated, tables added on the upper level, and the seats replaced and fixed in position on the other end. But even those cars to my knowledge retain the original bathrooms.
