I caught Amtrak #5(05) at Agency, Iowa this evening with three private cars from the original California Zephyr on the end. They were the dome car Silver Lariat, sleeping car Silver Rapids, and the dome car Silver Solarium. These three are on their way home after participating in the Norfolk & Western 611 excursions. Also, the last Superliner on the train was an extra snack coach. Don't know why that was there.
