What's exciting for me about this site is that you will see Amtrak trains here. Of course on most railcams operated by Virtual Railfan you will see a number of trains passing along which will include commuter, passenger, and freight trains.
So going through the Santa Fe Junction located in an area of Kansas City, Missouri (KCMO) known as West Bottom. If you click the link in the brackets to view the video you will see the number of rail lines that pass through at any given time. Kansas City Union Station which is a stop for Amtrak's Southwest Chief (with a decent layover according to the schedule) is said to be directly east of this junction. It's expected to see the Chief coming to and from Chicago and the Missouri River Runner between KCMO & St. Louis, Missouri passing through.
If this railcam has staying power it's probably very likely to be included on my Railcam page although what's shown in the vid itself isn't a regular station stop. We're just seeing all trains pass through.
