Glenloch was originally known as Glendale and had a railroad station on the Missouri Pacific Railroad. The Glenloch Town Company was chartered some time between 1850 and 1870. It was a small community with a post office established there in 1904. Eventually the Missouri Pacific Railroad discontinued the railroad from Topeka to Ft. Scott and tore out the tracks. Between 1913 and 1915 the post office was discontinued in Glenloch.
