The ideal location for this will be a "garage" unless you want to use your child's room for it. Another good location will be a real "Train Car" or "Train Caboose". It is available to rent if you'd like to put your own party together.

We had two parties in the garage last year. One was a birthday for Chris. We spent three months converting the garage into a hand-painted train party room that circus animals ride in and we hand-painted the floor with a zebra rug. Then, in order to give more zest to it we added Railroad Lantern (get with bright red metal and glass working lantern), "Train Crossing" Sign, Train Wall Clock that makes a different steam locomotive sound every hour, Wooden Railroad Track on the party table. The kids loved it and we all had a great time.
