Service to Plano began on April 30, 1972. Service to Quincy proper began on April 24, 1983 in response to the West Quincy station being frequently cut off by flooding. The suburban stop at Aurora, was discontinued on April 28, 1985, in favor of Naperville. Passenger service was cut back to Quincy on May 1, 1994, after a major flood in 1993 destroyed the original station at West Quincy. The "Illinois Zephyr" and the "Carl Sandburg" trainsets continue to cross the Mississippi River to layover at the BNSF West Quincy railyard for servicing between runs.
