I was told that the diameter of the bypass port on a triple valve for freight equipment is 51 drill or a little larger than 1/16 inch. Is this an accurate measurement on narrow gauge equipment as well? Also what is the diameter of the choke on a retainer?
This will help me visualize the events when the engineer cycles the brakes coming down a steep grade.
