First a good overall top-down shot of the unit:
The next view shows expanded detail on the cab roof. The box to the rear of the horn mounts the dual Locotrol receiver antennas. Note the re-piping of the horn from its original position over the headlights, and the cabling to the small FRED receiver antenna platform at the right rear of the cab. At some time, the air conditioner has been removed and the opening plated over. Also the rotating beacon has been removed from its platform. It also appears that the main Sinclair antenna has been removed, so don't look for this unit on the point any time soon.
The following detailed view shows the stack & radiator sections, with the see-through grilles on top of the radiator.
(The prototype also has trouble with paint sticking on the handrails
sometimes, as with some of our models)
