Happy New Year! As a newbee, I want to ask this first question - where to find/get an N-scale streamlined 4-6-4 NYC J-3a Hudson? This is for my 9-year old son's birthday. I have seen on the internet stories, pictures, descriptions about this train aka 20th Century Limited Streamliner (?). But I have not found a place that sells the model train yet. Thanks for your help.
