The Willis Tower looms over Amtrak's Chicago locomotive facility late at night. P42 188 at right awaits repairs after a grade crossing accident, while at left a new Siemens Charger backs a train into the wash bay.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
