In 1870, Rogers was involved in a suit against Jay Gould, James Fisk Jr., William H. Rasson and C. V. Nason alleging that Rogers was charged unreasonable freight rates when delivering their products; the court decided in favor of Rogers, delivering indictments against the four men. In the mid-1870s, Rogers ended production of textile machinery and began concentrating solely on locomotive manufacturing. Rogers customers of the mid-19th century continued purchasing their locomotives. The Louisville and Nashville Railroad (L&N) purchased so many locomotives from Rogers that Rogers gave the L&N a free locomotive as a thank-you bonus in 1879.
