This abandoned railway shows up as a Chicago, Burlington & Quincy line as early as 1895, and runs from Yates City to Vermont, Illinois. The section between Yates City and Dunfermline (near St. David, IL) was abandoned around 1994 by BNSF.
Today, the section of line from Dunfermline/St.David to Vermont is still in use thanks in part to Duck Creek Power plant. From Canton north through Farmington to Yates City, the right-of-way is in bad shape. A small portion of the tracks and the connecting wye at Yates Center was used for car storage as late as 2001.
The map above also shows a couple of abandoned spurs/branches along the still-active portion of the line between Dunfermline and Vermont.
