Freight service continued on a 3-mile (4.8 km) stretch of the line between Coleman Yard (at the junction with the Illinois Central Railroad Iowa Division) to supply coal to the powerhouse at Elgin State Hospital.

Rail remaining between the current museum site in South Elgin and the State Hospital was removed in 1978.

The Fox River Trolley Museum in South Elgin operates over a preserved section of its right of way.

[8][9] Since 31 March 1935, when rail passenger service was discontinued, routes in Aurora have changed, by 2013 under successor Pace little of the early city lines remained.

Curving east onto private right of way the line went through the freight interchange at Coleman (mile 4.5)[c], across the river on its own bridge, and continued south to an intersection with Fifth Avenue in St. Charles.

At State Street the line turned east and went to Third Street (Chicago Junction[d], mile 11.6), where it turned south, then east, jogged south on Route 31, then onto private right of way between Route 31 and the river.

By 1900 most Fox River area lines shared management, city car orders were often divided between Aurora and Elgin.

[17][18] The Elgin and Belvidere Electric Company left Elgin from the end of the Edison Street line at Wing Street, going 36 mi (58 km) west through the small towns of Huntley and Marengo to Belvidere, and a 14-mile (23 km) run through connection to Rockford.

[20] The Fox and Illinois Union Railway left Yorkville (where it also connected with the C.B.&Q) and ran 20 miles (32 km) straight south through Newark to Morris.

Eight passenger cars operated 17 trains each way in a day, and 3 streetcars provided local service in Joliet.
