I posted this prediction several times on the forum since MTH was not producing any new tooling. I figured Atlas O would drop out first. I am confidant that the items will split like Weaver and carry on for at least a little while longer. There are still a few un-produced items and paint schemes left to offer in O that were overlooked.
Thanks Mike W. and staff for all the great products and making my R.R. dreams come true through the years. I will be right behind you as well.
Good luck and enjoy your retirement!
