If you search this website: Shop - Extensions - Primary Station, you'll find an overview of the local train slots available. It says there that trainslot #41 is available at level 397 (for 2 million glass, fuel and titanium; or 1.6 million if you have the discount). With gems you can purchase it at level 383. Maybe that's what causes the confusion. Also I think that from time to time they change the #level at which you can get something.
