Andre: 26C's are what we had on the majority of Santa Fe locomotives. CCP engines (ex-IC/ICG for the most part) had the 26L's and for good reason! They were not equipped with operative dynamic brakes. Using the PASS position was supposedly "against the rules", of course.
12lbs. trainline/ER leakage in a minute? How did that guy ever get out of the terminal or move a train enroute with that, especially with all the expert "coulda' done, woulda' done, shoulda done" laying in the weeds just waiting for someone to stub their toe? I suppose we better get back to arguing modern versus period S scale railroading before someone accuses us of going off-topic, etc. Bob Nicholson --- In [email protected], "Andre Ming" <laming@...> wrote: > > Hi Bob! > > Yup, the PASS setting also works great for a leaking EQ if you have a 26L > brake valve.
