Normally they go as far as Leithton, but in the Summer, they sometimes go as far as Lake Zurich. This unit can sometimes be seen on road trains when it's going back to Gary for service. Coal trains are very unpredictable, but but here is the break down of coal trains that can possibly be seen on the Western Sub at any time. These are loaded trains that usually come off the UP at West Chicago and go to the Northern Indiana Public Services Company generator in the Gary, IN area next to Lake Michigan. These trains usually have UP power.
Empties come back the same way.
These are loaded trains that come from the BNSF at Eola. For this train, they usually send light J power from Joliet up to Eola to get the train. The power descends down the West side of the wye into BNSF's Eola yard, and hooks up to the train. The empties go back the same way. This special kind of coal is turned into coke for use in the mills.
