Have you ridden on an Amtrak Train? The only one I have been on is the Texas Eagle. I rode it round trip twice between Dallas and Chicago. I have never been on the California Zephyr which runs through Denver nor have I been on the Amtrak Winter Park Express.
Since I have been a railfan long before I ever heard of gecaching it is only natural for me to combine the interests whenever possible. Some of my other puzzle caches in the vicinity of this one also have a railroad theme.
About parking. Sometimes you can park right by the cache but you can always park by the parking waypoint.
You have to know or find something about these Amtrak trains to figure out where the actual cache is.
