So far (!) I've ridden in sleeping cars on the California Zephyr (X4!), Empire Builder, Coast Starlight, Lakeshore Limited, City of New Orleans, Cardinal (X2), Crescent, Southwest Chief, Sunset Limited (to NOLA). I always take the San Joaquin from Fresno to San Francisco to my medical appts. at UCSF. I absolutely L-O-V-E long distance train travel ... it's the ONLY way to see America!
