Yes, there really are 3 Villages plus the Toy Warehouses and the Reindeer Junction Switch Yard and the Parks and Greenhouses at the North Pole. And don't forget the Top of The World Mall.
The villages are located approximately 20 miles apart on a circle around the North Pole that is about 10 miles across and approximately 60 miles around.
The primary transportation between the villages and other areas is the North Pole Circle Railroad.
Santa's Village is located at 0 Degrees Longitude, on the Prime Meridian, approximately ½ mile south of the actual North Pole, not the magnetic North Pole.
Don't worry, because of Christmas Magic, and some help from the Northern Lights, none of Santa's 3 Villages or the railroad are normally visible. Even radar won't spot them.
Toy Town is located approximately 120 degrees "East" of Santa's Village and approximately 20 miles south of the actual North Pole, not the magnetic North Pole.
North Pole Center for Research & Development, otherwise knows as Tech Town is located approximately 120 degrees "West" of Santa's Village and approximately 20 miles south of the actual North Pole, not the magnetic North Pole . .
About 50 years ago the Elves who live and work there decided that "Tech" was short for "Texas" in the United States. So they set up a historic western town with the main railroad line running right down the middle of the street. They even appointed a "Sheriff", the only "law officer" at the North Pole. His primary duty is to greet tourists and help them when they get lost.
