Just saw another longer-than-usual consist for the southbound Texas Eagle at about 3:15PM this afternoon as it sped past my office window in Dwight, IL (not a station stop for the TE). 8 cars after the engine, most of them the usual Superliner cars; however, there were 2 single-level cars right behind the engine. The first one looked similar to an older single-level car (such as we used to have on the regional trains in IL before the Venture coaches were introduced, or maybe even a bit older). The 2nd one had a domed upper "observation level" just in the middle, but access to the car from other cars would have to have been from the lower level. Perhaps these were special cars? As single-level cars, I don't expect them to be included on Western long-distance trains on a regular basis.
