Telegraph is one of the 4-4-0s owned by the Atlanta & West Point Railroad in, and around the time of the civil war. The versions of said locomotive I have created sprites of are fictional representations. They are from an old Youtube series using HO scale models called The Blue, and The Grey. The sieres was created by Eddie-Sand back in the day.
Stanford is also a fictional representation of a Western & Atlantic locomotive from The Blue, and The Grey. If you ask me, I think Stanford is based on Central Pacific's Governor Stanford. But I'm not 100% sure on that. Eddie might be able to tell you a bit more.
