Both
Albany-Rensselaer and
Rochester have Amtrak Stations! Click on the location names for photos!
Boy...what some people will do for PR! The Marx Construction Company (who built the station) claims, on their website, that the new Albany station is the first new railroad station built in the U.S. since WW II. I don't have to go far to show them that the building plate on New Orleans Union Passenger terminal says 1954; I'm sure there are many other stations that were built after the war. Anybody have any additions?
Your "what some people will do" is a little extreme!
You may very well be right that the statement is incorrect, but if you tried to find evidence that there hasn't been another station built since WWII you could be misled as I was when I first looked and found the following web page:
http://en.wikipedia.org/wiki/Category:Railway_stations_by_year_of_establishment
My first reaction when I looked at the Wikipedia page is that the Marx company is correct because each year listed has (0) indicated as having newly established stations. Now if I just accepted that at it's face I would have gone ahead and made the statement that Marx made. However, taking a closer look I did find discrepancies.
First thing noticed is that all years both pre and post WWII had (0) so I looked a little further. In doing so I did find a few newly established stations in the US within the few years I checked. Then... another problem arose; I couldn't determine that the stations I found were actually newly built. A newly built status was not indicated on any I found but rebuilt or remodeled status' were. i.e. St. Louis - 2004. So I therefore determined that there is no creditable evidence that the pre WWII statement was incorrect.
Now further research could be engaged in, but at this point I found little reason to waste my time researching any further and if it were me I too would have gone ahead with the Marx statement on their web site.
Once again I want to emphasize that I am not saying you're wrong, just a little extreme on your opening statement!
