CORRECTED: Re: Pillars of Smoke Question

[NW Mailing List]

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.
