Also, how about the manufacturers eliminating the "working doors", i.e. able to open, on diesels and passenger cars? What a totally useless, and EXPENSIVE, feature, in my opinion.

The forthcoming Golden Gate Depot modernized heavyweight coaches will not have opening doors which permits the doors to now be the correct height. I am going to really miss stabbing at the doors with a pointed instrument as they travel around my layout just to make sure they still open.
