According to Amtrak's website (select stations, then midwest) there are 40 Long-term Parking Spaces at Kirkwood. I don't have any experience with KWD, but I've left my car at various stations in IL and IA for a month at a time with no problem.
At smaller stations such as New Haven, New Carrollton, or New Rochelle, Amtrak uses the same boarding procedure used by foreign intercity railroad operators and by commuter rail and mass transit rail systems in the United States. This makes sense, since that's how one boards a train. However, at larger stations, Amtrak chooses to ignore 150 years of accumulated human wisdom about boarding trains. So at Boston's South Station, New York's Penn Station, Philadelphia's 30th Street Station, and Washington's Union Station, people wishing to board intercity trains must go through a more elaborate process.
