I've got one engine waiting for parts (my fault), and one that loses it's TMCC signal, and I just haven't had a day to look at it. Everything else, from a 1932 #262 to a 1938 #238E to my Post War Berks, Hudsons, and K-5's up to my TMCC/Odyssey engines all work like a charm.
And all of my accessories and operating cars work too!
