Thanks for the incentive to learn more about Denver Union Station. I've been to the station, twice; once in 1985, aboard the eastbound AMTK California Zephyr, and once in 2016, having ridden the "A (Airport) Line" into town. The station certainly has changed, for better and for worse, during the intervening thirty years. Would that I could have seen it both in first class condition AND functioning as a station rather than a terminal. I can only guess at the "politics" involved in that "acquisition".
Its a fascinating station and a fantastic model! Remarkable work!
