At one time Bill, I emailed Atlas but never heard back. But Paul Graf has mentioned some of the problems they've had including having to repair dies on other products. So if they had to invest tens of thousands of dollars to repair the IR dies, well one could speculate how they might not feel it is worth that money for the price point they could sell them at.

Atlas also recently purchased the Walther's N scale dies and is incorporating those items into the Atlas line. By the amount of new HO and N scale monthly announcements, you can see where their real market is.
There are places that still have stock of Atlas IR cars. Forum sponsor Public Delivery Truck for example:
