Very nice.
Did your NOS loco have congealed cylinder lube?
i had to soak my nos frank s cylinders with liquid wrench for a couple of days in order to free them up.
They are wonderful.
Ill have to have a run soon…its been quite a while. My layout has grades, which make downhill curves rather exciting…lol.
Fwiw, I check all the screws , especially drivers and cylinder/frame attachments before every run. They work loose surprisingly easily.
