Maybe someone from around St. Louis can help on this. This was somewhere in the St. Louis area. I don't know where or when. I'm trying to figure out where it was. 60's or 70's? The negative is reversed. The loco is 400.

Looks sort of like the Wabash, Frisco and Pacific Rail Road in the Glencoe area of Wildwood, MO. It's a bit west of St. Louis.

I've been searching and got lost viewing their videos. I didn't see that particular one. The 400 they have on their roster isn't that one but maybe they just don't have it anymore. I've been out there a few times but that has been many years ago.

The locomotive definitely has WF&P on the side so it has to be the railroad with those reporting marks.
If you are rail fanning to St Louis, it is a must see. Look them up on the web.
ACY - Duh! Why didn't I look closer. Since it's reversed, I didn't try to read the cab. Thank you.
