About This Trail

The Aurora Branch runs southwest from the Volunteer Park junction in Wheaton to the Fox River in Aurora. It passes the Danada and Herrick Lake preserves, the old utility poles of the CA&E at St. James Farm, and the woods of Warrenville Grove, where it crosses the West Branch DuPage River and meets the West Branch DuPage River Trail. Past Warrenville it throws off the Batavia Spur, skirts the south edge of Fermilab, crosses Farnsworth Avenue, and drops through Aurora's neighborhoods to the Fox River Trail near Broadway. The surface is hard-packed crushed limestone that turns to asphalt for the last miles into Aurora. Beyond the Wheaton end lie the Main Stem and the Elgin Branch.

RailTrailWx TIPS

Illinois Prairie Path: Aurora Branch

Your comfort. Prognosticated.

  • Most of this branch is open, with real shade only in the Warrenville Grove woods and along the river; on a hot afternoon the shaded miles near Warrenville are the place to rest.
  • The corridor angles from east-northeast to west-southwest, right along the summer southwest breeze, so the ride out to Aurora is often into the wind and the return to Wheaton gets the push.
  • Wheaton sits roughly 120 feet above Aurora. The grade is nearly flat until the final descent into town, which is the steepest sustained pitch on the branch and a short climb on the way back out.
  • The stretch past Fermilab crosses open prairie with nothing to break the wind; a crosswind from the north or south is felt most here.
  • The Fermilab Trail shortcut between this branch and the Batavia Spur is open dawn to dusk, and everyone 18 and older must show government photo ID at the gate.
  • Horseback riding and cross-country skiing are listed uses on the path; the shaded Warrenville Grove miles hold snow longest.

Trivia

  • The Aurora line was the first the railroad opened, on August 25, 1902, and the Batavia shuttle split off from it at a point first called Eola Junction and later Batavia Junction.
  • The CA&E ran milk trains from May 1, 1903, an early example for an interurban.
  • At St. James Farm the railroad's line of utility poles still marks the old right of way running diagonally across the preserve.
  • A dam built in 1847 to power a gristmill stood on the West Branch DuPage River at Warrenville Grove until its removal in 2012; the limestone abutments from the 1930s are still visible.
  • At neighboring Blackwell Forest Preserve, a 13,000-year-old woolly mammoth skeleton was found in McKee Marsh in 1977.
  • Blackwell's Mount Hoy, a birding overlook and winter tubing hill, began as a county landfill that operated from 1965 to 1973.
  • Fermilab's bison herd was started in 1969 by the lab's first director, Robert R. Wilson, as a reminder that science is a frontier.

History

The Chicago, Aurora and Elgin ran its last passenger train at noon on July 3, 1957. The line had opened on August 25, 1902 as the Aurora, Elgin and Chicago, an electric interurban that drew power from a third rail. It carried commuters to the Loop, milk from Fox Valley farms, and some freight. Postwar expressway construction cut its direct route into downtown, and riders drifted away. Freight ended on June 10, 1959, and the Illinois Commerce Commission authorized full abandonment on July 6, 1961. On September 30, 1963 the Chicago Tribune printed a letter from Morton Arboretum naturalist May Theilgaard Watts asking for a footpath on the empty right of way. DuPage County bought the property that same year. Her supporters incorporated the Illinois Prairie Path in 1965, leased 27 miles from the county in 1966, and had the first trail signs up by 1967. In June 1971 the Interior Department named it a National Recreation Trail. A state lease in 1972 pushed the path across Kane County to the Fox River, and in 1979 it grew east through four Cook County towns. DuPage County took over maintenance in 1986. This segment is the Aurora line itself, the first the railroad opened in 1902. Its Kane County miles into Aurora came with the 1972 state lease that carried the path to the Fox River.
