Great video.....you can see the current Amtrak station in both video's just east of the old Burlington Station.
I used that station many times when I lived nearby in downtown Omaha, in the early '70's...
And prior to that, I passed thru it several times. I too, recall the wonderful collection of streamliner's and domeliner's that served Omaha. Omaha, similar to places like Kansas City, was situated geographically to benefit from being on the main corridor(s) of rail transportation. The only downside, was that because of their longitude, they saw most of the top trains during the late night hours....similar to places like Pittsburgh and Cleveland. But there were many lessor trains serving the daylight hours, back then.
I recall my 'fantrip' where I took the "City of Everywhere" from Chicago to Omaha, walked across that bridge linking the UP station to the Burlington station for the final time, and came back on the CZ....
