Suggested correction: That's not a reflection of a crew member's face at all. It's just the reflection of the perpendicular wall.
Trivia: The map of Duke's Railway is actually a map of railways on the Isle of Wight, flipped upside down. The line in particular which the Portly Man points out, is the Isle of Wight Central Railway.
