1. Engineer - Gentleman on the left 2. Fireman - Gentleman on the headlight 3. Conductor - Gentleman with the vest and pocket watch/chain attached 4. Switchman - Gentleman on the pilot and the lantern next to him 5. Brakeman- Gentleman on the right Anyone else want to chime in!
The guy on the headlight isn’t that young. He had to be pretty agile to get there. The switchman is wearing what appears to be an English cop’s helmet, odd.
