Re: Bohn Ventilators was Truss Rod Reefers

Hi Mike,

The ventilators were louvered hoods hinged over the ice bunker openings - they had to be swung out of the way for icing. For refrigerator service, a hinged plug inside the ventilator sealed the bunker - there was no conventional hatch cover. For ventilator service, the plug was locked up into its open position inside the hood, and the hood acted as a scoop to direct air flow into the car. The ventilators at opposite ends of the car faced in opposite directions, so one pair always faced forward in a train.

The Santa Fe didn't order any cars with ventilator hoods after the Rr-W class of 1920, so the ventilators might have been more trouble than they were worth. Many of the cars that had them apparently kept them into the 1930s, however.

So long,
