Bringing up the rear of a Union Railroad ore train is caboose 101, a welcome sight in this era of Flashing Rear End Devises (FRED). The train is passing the railroad's Hall Shops in Monroeville, Pennsylvania. A quartet of MP15DC locomotives ― 28, 25, 19 and 31 ― are in charge of this southbound train.
