Turpin was named for Carl Julian Turpin, a son of Thomas James Turpin and Elmanda (Kennerly) Turpin. Carl was born on 10 Aug 1871 in Quantico, Wicomico County, Maryland. He died 20 Nov 1942 in Oklahoma City.

Carl J. Turpin was the general overseer of the Beaver, Meade and Englewood Railroad (BM&E). In 1918, two farmers from Hardtner, Kansas, Jacob Achenbach and Ira B. Blackstock, requested his assistance. Messrs. Achenbach and Blackstock had been asked by farmers in Beaver County and the surrounding areas to build a railroad through the Panhandle suitably that their wheat crops could be shipped to outlying markets. Achenbach and Blackstock knew how to build the railroad, but they needed someone to govern it. That is where Carl Julian Turpin came in. Turpin had plenty experience as a railroad man, his career initiation in 1888.

Described as a “by the book” type of general manager, Turpin was a stern, well-groomed man. He worked without salary, but did get stock in the line, from 1918 until 1926. At its height, the BM&E ran from Beaver, Oklahoma through Turpin and Eva, Oklahoma and continuing to a relationship with the Santa Fe Railroad in Keyes, Oklahoma. The line connected in the reveal of the Katy at Forgan and the Rock Island at Hooker. The BM&E was eventually sold to Missouri-Kansas-Texas Railroad (M-K-T or Katy) in 1931.
