Gordon,

That would be my guess. That gladhand is going to have quite a kick when when the air dumps! It certainly is not standard equipment on road units. It must have been added to units assigned to pusher service. I've never seen one before.

I'm referring to the cushion-like device below the coupler. I would estimate it is about 18" x 24" and has wrinkles on its surface. Is it a pad to cushion the device on the end of the trainline hose when the hoses separate and the nose coupling and device fall against the pilot?

Gordon,
Are you referring to the item attached to the air hose or the "bungee" type support of the pad and hose glad hand. I think one of the devices that allows the coal train to be cut off on the fly with the angle cock open is attached and ready for the next train to push.

Skip,

Thanks for the picture and the explanation, but the picture begs another question. What is the scoop on the cushion-looking item below the coupler?

Attached is a photo I took 5-23-06 at Whitethorne of the 9801 pusher equipped with the "cut off on the fly" equipment. Notice that the 9801 MR hose (main reservoir line) is hooked to the device and an ACT (actuating line) from 9801 is hooked to the cylinder above the pin puller. When the 9801 is connected to the last coal car in a train to be pushed, as I understand it, another device is inserted between the train line on the 9801 and the train line on the last car. When the engineer is ready to "cut off on the fly" he "bales down on the independent brake handle causing the actuating line to allow MR air into the cylinder to lift the cut lever opening the knuckle and cutting the locomotive off. At this time when the train line hoses separate, the inserted device senses the cut and shuts off the train line air on the last car and stays with the last car. I spoke to an engineer at Whitethorne sometime later and he told me that the pusher always goes into
EMERGENCY and the engineer on the pusher "holds his breath that the device in the train line works to keep the coal train being pushed to NOT "big hole".

As added info, Whitethrorn pushers using the cut-on-the-fly device go into emergeny when they cut away from the train. The fly device only closes the angle cock on the cars.
