Regarding lubricants (and I post this about once a month)....
Your locomotive is a model of a piece of heavy machinery. The stress/strain curves look the same for the real thing (pardon the engineer speak). Best choice in oil is automotive motor oil(10w40 preferred). The best grease is used in automobile power brake assemblies (Sta-Lube Hi Temp Disc Brake bearing grease).
Dawn is an excellent choice for cleaning. And WD40 (not a lubricant) is great for dissolving old grease.
Good luck!
