Nice photos. That second one . . . . a neat way to turn the engine around . . . . when there is no “Y” or turntable available . . .

I just notice something that the front end of that steam switcher has duel pole pockets to push and spot frt. car on adjacent siding. Very usual. Usually only have them on each end of Eng. Take a look.
