Hi Bob! Yup, the PASS setting also works great for a leaking EQ if you have a 26L brake valve. You're poop outta' luck with a 26C valve. (2 positions: In/Out.)
In fact, I know of an engineer (know him very well, in fact) that just the other day had a 4,000 ton train, and the lead locomotive in his consist had a 26C with an EQ that leaked and thus wouldn't maintain. With a train behind the consist (and all the air leaks that accompany a train), once a minimum reduction was made (about 6 lbs), it would draw on down to 12 lbs in less than a minute, and keep on drawing off your air. Of course, left unabated, you will be stopped within another minute. That's a prescription for disaster. Anyway, this engineer I know very well said "to heck with this" and used the Regulating Valve to safely bring them down the hill to a drawbridge (in the up position) on a river. ----- Original Message ----- From: shabbona_rr To: [email protected] Sent: Monday, December 05, 2011 5:09 AM Subject: Re: {S-Scale List} Moderling Earlier Eras in S Andre: Judicious use of the regulating valve will prevent that from happening. I remember a story about a railroad that wanted to fire an engineer for descending maountain grades by using the regulating valve to maintain brake pipe pressure with K-type brakes. They got all set up for a ring-a-ding-ding kangaroo court, and even had a representative from the air brake manufacturer to drive the final nail in their case against the engineer. His testimony wasn't exactly what they wanted to hear. He testified that the engineer had better use the regulating valve, unless the railroad wanted a pile of scrap at the bottom of the mountain. Case closed! Bob Nicholson _________________________________________ PS - the "passenger" setting on #26 brake valves serves the same purpose. That's how we got down the hills with no dynamic brakes ________________________________________________________________ --- In [email protected], "Andre Ming" <laming@...> wrote: > > Gotta' be careful though when decending heavy grades (as on my V scale Colorado Midland route)... or you can... umm... uhh...
