Each RR line had 12 each so that alone is 36 plus the Amtrak cars if you are counting them. Also the two PRR cars. The full sets recently delivered may have additional numbers and I believe that a least one special run car was issued by Atlas as a bonus. Would like to hear from the folks that may have the complete sets that were sold recently. The list of releases on the Atlas should also tell the story. You will have to go back some six years.
