I think you need to look for references on the web site to "new tooling." Unfortunately, that reference may not be there in many cases. I think the biggest "give away" that a model is old tooling is the "claws" that Athearn used for opening doors. However be aware that many of the "modern" boxcars in the blue box kit line as well as the modern boxcars made by MDC did not have opening doors, but still had the cast on grabs.
