spikey Posted October 8, 2022 Share Posted October 8, 2022 I am reading the June 1961 issue of "The Railway Magazine" (as you do), wherein is a fascinating article titled as above. I learn that "Every three months, the section permanent way inspector, in addition to his normal examination, takes calipered depths of rails, notes expansion joint openings, corrosion, chair-gall, and other relevant features." What, pray, is "chair-gall"? Link to post Share on other sites More sharing options...
