From the car that pic was taken in the late '60s-early-'70s. One does wonder what the guy is doing up there.
He's passing hand signals being given by another Trainman who is out of sight of the Engine Crew. That way, movement can be made regardless of curvature or other obstacles to the Engineer or Fireman's ability to see the employee who is controlling the movement. This has not been done (nor allowed) for years, as radio handsets have made it unnecessary.
