Monday 24 Feb. I spotted Amdinette 48201 behind baggage car and in front of transition sleeper in Dallas Union Station on WB Texas Eagle.
It appeared to have down/up connecting door w/transition sleeper, but doubt it was in service. And yes, there was a Superliner diner, but no there wasn't a Sightseer lounge. Eagle did have three P42s (204-187-99); it usually runs two.
