Re: Wanted: K-1 triple valves

Following up on what Brian says about obtaining copies of some of the old Wabco manual or other air brake tutorials of the time, as someone who has worked in the cab a little bit I see a great advantage in understanding what is taking place with the brakes back on the cars. Put rhetorically, is it enough to understand how to make a brake application and recharge the train as needed, basically drive the train? I think not because if you get in a situation with say a slow to function feed valve, difficulties with the brake system on the engine or on the train such as a dynamiter it is important to visualize what is taking place as you may be able to take steps to work around the difficulties. A bad malfunctioning feed valve for example can mean you have to go carefully to full release to charge the train. But that has it's difficulties as you may overcharge the train, or as you taper off feeding air, you may end up having cars set up again as there is a momentary drop in pressure as train line pressure continues to stabilize. The importance of understanding what the air flow is likely doing with respect to the triple valves can't be understated. If you ever have to run in this way, you can expect some slack action, but it is possible to operate at least back to a terminal.
