I forgot to mention my wish list item and that would be steel gons in the 40 foot range--not long mill gons that have been produced too frequently. Of course, that brings up the same problem that Richard mentioned with the 40's single sheath boxcars--lack of standardization for multiple roads. And the folks in the model train manufacturer marketing department probably don't get excited about these cars as they usually are rather nondescript compared to house cars often with larger logos plus slogans.
