I ordered the Ferdinand Magellan Presidential rail can and was worried about it being produced. I wrote Ryan Kunkle of Lionel and asked. He answered back as follows.
No, these are on order and should be arriving this year. The New Haven and Great Northern cars have not yet been ordered. Thank you, Ryan
If you remember that car was with the group of Pullman cars. This probably means there was enough orders for the Pullmans to be made.
