Paper train catalogs were never accurate and have become a thing of the past. You don’t always receive what was shown, especially colors.
I would like to see a rotating 360 view of the item like the automotive sites have. Web access to everyone and real time changes / updates could be made by the OEM's on the fly.
Example: It’s important to me to see the numbers on the front / back of an engine along with head lamp and railing details. We could never get that view from a catalog. Car dates and trucks are also an important detail for period modelers as well.
