I've been converting my diesels not equipped with command control to ERR TMCC. I've been thinking about picking up an older MTH Premier Santa Fe 2900 class Northern at some point and converting it to PS3. According to MTH the older models have a 054 minimum curve: https://www.mthtrains.com/20-3013-1
I have some 054 curves on my layout so it sounds like it would work on that part of my layout. Has anyone run one of these locomotives on 054 curves? Did it run ok? How much overhang does it have on 054? I have a MTH Premier Southern Pacific GS4 Northern and it works on 054 fine but the 2900 class is a larger locomotive.
