Re: Brake Testing Appliance.

Brian:
They are both indeed single car test units. The inline one I *THINK* was made by Art Randall.
Doug and I are both creating single car testers for use on the C&TS museum fleet in 2017.
It is being kinda fun seeing what we each come up with.
The yellow one might be cooler with it's dual gauge, but I got so used to the inline version that I did not spend much time with the yellow one.
The inline one IS awkward to use, but it gets the job done.
The drill that Art taught me was to test on the car and if the triple valve fails, take it off for further work on a shop test stand.
4 years ago we made our own shop test stand . The C&TS test stand is in their shop and we were just getting underfoot.
Pretty simple, a scrap reservoir and Russ Hanscom fabricated a fake cylinder with gauge ports.
When Russ gave me the fake cylinder he said he had tested it to 600 PSI.
"Will that be enough?"
"Um, yes, I think that allows for an adequate safety tolerance".
(Trainline pressure is 90 PSI)

I am posting this diatribe so other folk can chime in since I have been drawn into the vortex of making brakes work on the Museum fleet.
Never fear, real railroad employees do that work on passenger equipment!
