It was sometimes called the "Diamond Jo Line" because of its developer and sole owner, Joseph "Diamond Jo" Reynolds.
Construction of narrow-gauge tracks began in April 1875. Trains began operating on the 21-mile line a year later.
On October 16, 1889, it was converted from a narrow-gauge railway to standard gauge in about three hours, after several months of preparation. The Malvern brick roundhouse and turntable were modified for standard-gauge operation, and remained the principal locomotive shop for the railroad.[1]
Reynolds was a successful steamboat operator from Chicago, Illinois.[2] He gained the name "Diamond Jo" by marking his steamboats with the name "Jo" surrounded by a diamond. Reynolds was also known as the "Steamboat King."[3][4]
